get the Bore Buddy reliability kit, comes with better extractor springs, the plug and an insert for the charging handle. Makes a huge difference in the number of jams, Best 30.00 you will spend.
I have that kit with the Bore Buddy kit. I tried it out a couple of weeks ago. One thing I found out was that you cannot rest the bottom of the mag on the table/bench when shooting, or it will cause FTF's & stove pipes. So basically, my kit worked great as long as I wasn't resting the bottom of the mag on anything.
Good to know! These dedicated 22 ARs take a bit to get sorted. I just converted to the 15-22 magazines with the Redi Mag adapter. I’m getting bolt bounce also so I might get the bolt weight from Bore Buddy.
Bore Buddy has a number of great products for the AR in 22LR, and I do like the original Bore Buddy. I bought a few more upgrade parts from them also primarily as preventative care. I now have some spare parts, too. It’s a really affordable way to shoot, and A TON of fun!
I bought this set and had a ton of problems in my Ruger AR556, specifically failures to fully eject with the brass getting caught up in the ejection port. I did two things to resolve the issue and now it runs great. 1. Put a little fuzzy side velcro tape on the top front of each magazine to take up some of the slop, and 2. Purchased an aftermarket charging handle for this kit that does not have the long groove on the underside.
Here’s what I did to fix bcg frame movement. Made a tab that fits over the end of the cmmg bcg that fills the gap and makes contact with the upper part of the lower. Drill a hole in the tab so that it will hold in place by the spring rod. No more back and forth slop, and no need for a buffer tube plug for the added pressure on bcg. Tab does it all.
I took mine to the range today, I had my buffer in place. Had 3-7 malfunctions on every magazine. I did lube it, failures to feed, failure to extract, stove pipes, quite frustrating, thinnking that for another 200 bucks could have gotten a dedicated, built from the ground up 22LR AR
@@siperstein I'm sure the whole thing is going over in your mind, so please pardon my question, as I definitely do not want to put salt in your wound. Did you try different brands and types of ammo? I imagine you did, but since you did not mention it, I figured I would ask. Myself, I absolutely have tried many 22LR brands and types, and there are some that just SUCK. Others that do great. One other common cause of jams and misfeeds is a loose fitting mag. Someone somewhere sells shims to put on the mags, but I doubt that that is necessary as most people can figure something out on their own. If someone is using the magazine as a place to put their offhand, it can cause those types of issues, in which case the resolution is simply putting the hand elsewhere. That is one reason why I like an aftermarket magwell, like the one you see on mine in the video. There are those who love to hate magwells and will tell me so, but I don't care. I have one on my 9mm, too. Many will simply place their offhand on the handguard. Some put a stop on the bottom of the handguard to remind them to keep their fingers and hand away from the muzzle. If the AR is a carbine (with a 16" or longer barrel) then they can use a vertical grip. Those are the only two things that came to mind right now for your issues there. I hope it helps but more so, I hope you can get it worked out.
@@radomguy9678 thanks for your kind reply. Tried CCI, Federal and Winchester all copper options. Got equal counts of problem. I’m going to try holding the magazine steady as you do. Thanks again
@@siperstein A good way to secure the magazine for a test is to shoot it from a bench with the bottom of the mag resting on the bench. That will keep it stable and still. I do not touch the magazine when shooting it, but I do make sure that it is in there good and tight. Good luck again - I know that this kind of thing can drive a person batty!
Thank you for your video. In summation, you were running it without a spring/buffer (provided rationalization on how why at a first glance that might not be needed), placed in spring/buffer, and it ran better?
That’s correct. Previously someone was commenting basically calling me an idiot for my error. The way I look at it is that I am human and did what we humans do: we make mistakes. I thought it might help other imperfect humans who may make or made the same mistake. Are you building a dedicated 22LR AR, or using a conversion kit with an existing firearm? I was recently watching a UA-cam video of a guntuber in his 50’s discussing how his factory 22LR AR has become his favorite shooter of all time. I have to agree with him with my particular 22LR AR - it’s so much fun to shoot. I could shoot it for hours and hours and not get fatigued by it or tired of it. But mine was a whole heck of a lot cheaper to build than a factory 22LR AR pistol. Whatever you do for yours , enjoy!
More than likely all you will need is the buffer spring and any old buffer. I put a 3 ounce buffer in mine simply because that’s what I had sitting in a drawer, and it works awesome, as I mentioned in the video. I was talking to some other AR 22 builders recently and some used buffers with no weights inside of the buffer and it does the job well. As I mentioned briefly in the video, too, one could also use a “bore buddy” in front of the buffer if reliability is still a problem even after using a buffer and buffer spring. But my experience in three different AR’s is just fine as it is now. Enjoy your build and thanks for commenting!
True, of course, when it is used in an existing AR, where one would only be swapping parts (BCG and magazines at a minimum). The point of my particular video is about an AR pistol or carbine that someone would build from scratch, so no parts would already be in the gun. I worded the title of the video intentionally, specifying the word “build.” This video does not apply to someone who has simply swapped out the BCG and mags, unless that person removed the buffer for one reason or another and experienced problems like the ones that I did in the past. Enjoy your kit!
@radomguy9678 I understand that, however the concept is the exact same. You MUST run a buffer and spring for it to work properly or buy a block off plate. This isn't stated as it's implied when you buy the kit because whether you buy a conversion kit or build a dedicated .22 AR, they are only setup those two ways . It's definitely a learning curve when you first get into building a gun.
@@nebick27 If your point is to state that I made a mistake. Then, yes, that’s pretty much the reason why I made the video. To explain what I did wrong. I am actually human, not a UA-cam bot, and I made a mistake as humans do. I don’t know why folks comment just to say that I made a mistake.
My Taccom bcg/ barrel on my dedicated ar .22 has a delron buffer plug but to eliminate some weight i removed the heavy buffer from when it was a 300 Blkout and put the plug in. It also has a standard Bore Buddy. Put another 60 rds of federal bulkbox through it today with 100% reliability. A fun rifle.
Federal bulk ammo is one of the few ammos that I have not tried with mine yet. I have tried the Federal Auto Match 22LR and it did not cycle well, though. CMMG recommends High Velocity 22, preferably with a 40 grain weight bullet, with this kit. I have found that to be quite true in my pistol length 8” barrel, meaning that slower/standard velocity ammo is not so reliable with this combination. However, using a 16” barrel, it is not as finicky about standard velocity ammo. It can function quite well with standard velocity ammo in the 16” barrel, but I do not have exact numbers on reliability, as it has been a long time since I tried that. Thanks for writing!
@@radomguy9678If I remember correctly, the CMMG website recommends 36 gr copper plated.22LR. Doesn't mean 40 grain wont work. But I'm almost sure they're recommending 36 grain over 40.
I hope this is my problem I built an American Tactical all polymer upper and lower with a pencil barrel chambered in 5.56 and put my cmmg .22 conversion kit in. I also did what you did by removing the buffer spring and buffer for weight reduction. gonna try putting them back in to see if it solves my problem.
Yes, good point, or a stack of quarters. When I made this video I had not yet used a Bore Buddy. I have one now because I ordered some parts for the bolt carrier and a replacement firing pin, so I spent a couple bucks for a Bore Buddy to see if there was any difference between it and the setup in this video. No difference for me, it works well either way, but it's good to try things.
Mine won't shoot three shots without a double or triple jam. Requiring pliers to clear it all out. Very frustrating after all the money I spent on a dedicated upper.
Do you have an option of trying the CMMG kit with a different AR upper than your dedicated upper? Has it worked successfully in another AR with the same ammo that you used? I actually have to do some more troubleshooting work with my 22 here. My dedicated AR 22 that I show in the video was doing great after I made the changes described in the video. Thousands of crazy fun rounds. Then suddenly it was jamming like what you explained: I needed pliers to pull out a jammed spent shell each failure. It was with its “favorite” ammo, bulk Aguila Super Extra High Velocity 40 grain copper plated round nose. I happened to have some different 22LR with me, so I tried that. It was Federal High Velocity stuff (NOT the Federal Auto Match 22LR). Much to my surprise, it suddenly ran great. I only had a hundred rounds of that Federal with me, unfortunately. In my case, I believe the batch of Aguila that was failing was not within the same specifications of all the other exact Aguila 22 that had worked so well for me. One separate indicator that the batch of Aguila ammo was not up to par was that when loading my mags with my McFadden mag loader, this “offending” ammo was not running smoothly through the mag loader. In my experience, when that has happened, the OAL (overall length) of the given 22LR is longer than a typical 22LR round is. I THINK that the longer bullets being fed into the chamber of the CMMG bolt adapter was bumping into spent cases being ejected. It basically seems to have thrown its timing off. But again, I only had that 100 rounds of alternate ammo that day, so I did not get much of a chance to keep running it through the AR. Next time I go to the range, I’ll bring a good supply of CCI MINIMAGS (the round nose version), and some of that Federal ammo if I still have some. Also, I plan to bring another AR with me, and swap out its 5.56 BCG out for the range trip for testing, if I need it. So in my case, my new problem seems to be ammo related but I can’t be sure yet, as I have not had the time to re-test. It’s incredibly frustrating when this happens, which I think is especially frustrating when you build the gun yourself, because then you start second-guessing everything that you did when building it. I actually also might replace the recoil spring of my CMMG kit, too. I’ve certainly successfully and happily fired a ton of 22LR using this kit, so it might be time to replace the spring anyway. I could throw more thoughts about this your way, but the whole thing can be pretty maddening. It’s good to try just one thing at a time, if possible. Good luck with yours. Let me know if there’s anything I can do to help.
Something I forgot to mention: how old or new is your CMMG kit? The ones from four or more or so years ago have a different chamber adapter than the new ones. The older ones were made of a few parts whereas the newer ones are monolithic/one machined piece of metal. Look at your chamber adapter (the part that inserts into your AR’s chamber): is there a crack/split that goes down the length of the adapter? This is a common problem with the old chamber adapters. These older design will probably have a brass base to the chamber adapter whereas the newer style are all stainless steel. Please let me know if this helps.
@@radomguy9678i really appreciate the feedback and pointers! You gave me some insight as to what else i might need to look at. Mine jams with any kind of ammo, it is virtually a singleshot. Next i guess is hand polishing everything in and out, trying a different lube, and repthe recoil spring and see what happens. On the plus side it is very accurate; rabbit-head accuracy to 100yds with some brands. Im a helicopter mechanic & Harley mechanic and so far trying to be a CMMG mechanic😅I'm seeing a close relationship between the three: For each hour of operation, 3 hours of repairs & maintenance are required 😶
@@stephenembrey883 oh man, I am sorry to hear that you are still having to mess with your conversion kit! But it sounds like you are taking it in stride so that is good. I know that you replied telling me that you have a dedicated upper. Does that mean that you have an upper that was made for 22lr, and not for .223/5.56? It is really hard to describe what I am asking about the “chamber adapter.” It is part of the CMMG kit. If you would, please check out the link that I will share below. That is an example of a crack in the chamber adapter. The same thing happened to me when I first bought my conversion kit. It was running great then something broke and it basically became a bolt action gun. I called CMMG and they sent me a new chamber adapter part and it fixed the problem. www.reddit.com/r/ar15/comments/i86hy3/cmmg_22_conversion_bolt_has_large_crack_in_it/#lightbox
@@radomguy9678 AT3 Tactical decided to send me a completely new unit and it works perfectly. ccmg however just wanted to send the part that was sticking in to barrel and it would takes them weeks. So AT3 customer support is great..he even send me an extra magazine for my trouble. I'll be sticking with them from now on. I still may get the kit for the conversion kit to really get it dialed in.
Sorry for this late reply. UA-cam settings held your comment for review (I have no idea why) and I did not know that. That is some good customer service from AT3! I am glad they helped you out. I actually have had good customer service from CMMG, by the way, in case you wanted to know. When I first got the kit several years ago, it used to ship with a different kind of chamber adapter. That old chamber adapter sometimes would crack down the middle. Mine did just that. I called CMMG and they sent the new style one out to me right away. Also, this past summer I dropped one of my CMMG brand mags for the 22LR conversion kit. Usually no big deal but it landed smack on the feed lip (the very top) onto my concrete cellar floor and broke. I called to ask if I could buy a new left side magazine housing from them, as it was my error. They sent me a whole new mag instead, free of charge . From my own experience, I think you could count on them to help you if you were in a bind, but obviously I cannot guarantee that, since I am just a user of their product, like any other average Joe. Enjoy your AR, and thanks for the reply!
If i accidentally touch the mag while holding it or resting on the bench, i get failure to feed, do you think this will help it? Probably not, cause its the mag that moves and can't cycle a new one, too much mag play
I don’t think this would help your exact issue, no. However, your problem is not uncommon. People will add some sort of shim to the magazines so that it will fit more securely in the magwell. There is a product by “Catch22” that I have heard of, but not tried myself. It is a shim that creates the good fit for the mag in the magwell, but also allows for using Smith and Wesson M&P 15-22 magazines. However, I cannot confirm if it works when using the CMMG mags. I find the Black Dog magazines to fit tightly as do others but they do not drop freely for me when pressing the mag release button. If I were having that issue, I would try shimming the mag with electrical tape, running vertically, until I would find the right fit. The electrical tape may not be a permanent solution but it can help troubleshoot a problem. I have used JB Weld brand epoxy for things like this, as a permanent solution. If you find that the gun operates properly when the mags are shimmed with a certain amount of electrical tape, you could add a layer of the epoxy to the side of the mag, let it dry, and slowly sand off epoxy material until it is the perfect fit. And it will dry very close to the original mag black color. Of course, try the black electrical tape first to see if shimming fixes the problem. Good luck! That issue is pretty common, so I think you will be able to fix it without much trouble.
Thanks! The reason I picked it up is because I was not comfortable wrapping my fingers around the handguard with it being so close to the muzzle. I found myself instinctively holding the magwell when shooting it, so I looked for and found the magwell grip that you see in the video. I love the feel of it. It would be really good for close quarters use. Thanks for your comment!
If you are talking about the Chinese knockoffs, I'll agree with you. However, the one that I have in this video is an original made by the Israeli company FAB Defense, and are excellent quality, and very comfortable and useful for me. Chinese companies break copyright laws like mad and make crap imitations to boot. Suckers buy them from Temu and other places.
And it looks like they are a really good price these days. I paid around 45 for mine a number of years ago, directly from their website. Now they are only 22. They are also the original designer and manufacturer of the MOJO magwell / funnel. I am not into the style or the current style of MOJO magwell, but the quality is excellent. Knockoffs use a cheap plastic and use screws that thread directly into the plastic. FAB Defense uses machine screws that mate with nuts that fit into a mold in the opposite side of the magwell. Again, excellent quality.
@@contractor556 And, the reason why I made this video is because I absolutely love the conversion kit and I know others do as well. I knew that it ran great in my carbine. With the issue that I was having with this pistol, I could not find the solution. Sure, a “Bore Buddy” would likely have solved the issue just the same, but I had never read anywhere that a buffer spring was necessary with the kit, so I did not even consider it at the time (if someone chooses to use a Bore Buddy, the Bore Buddy it takes the place of the buffer, and the buffer spring is needed). Hopefully I explained this well enough in the video anyway. If you do have any questions, I’ll be happy to help if I can. I hope you can get one of these awesome conversion kits; you won’t regret it!

I mentioned in the video that the Bore Buddy was an alternative to using the buffer, yes. Bore Buddy makes great products; I have a few of their items.

It was with its “favorite” ammo, bulk Aguila Super Extra High Velocity 40 grain copper plated round nose.
I happened to have some different 22LR with me, so I tried that. It was Federal High Velocity stuff (NOT the Federal Auto Match 22LR). Much to my surprise, it suddenly ran great. I only had a hundred rounds of that Federal with me, unfortunately.
In my case, I believe the batch of Aguila that was failing was not within the same specifications of all the other exact Aguila 22 that had worked so well for me. One separate indicator that the batch of Aguila ammo was not up to par was that when loading my mags with my McFadden mag loader, this “offending” ammo was not running smoothly through the mag loader. In my experience, when that has happened, the OAL (overall length) of the given 22LR is longer than a typical 22LR round is. I THINK that the longer bullets being fed into the chamber of the CMMG bolt adapter was bumping into spent cases being ejected. It basically seems to have thrown its timing off.
But again, I only had that 100 rounds of alternate ammo that day, so I did not get much of a chance to keep running it through the AR.
Next time I go to the range, I’ll bring a good supply of CCI MINIMAGS (the round nose version), and some of that Federal ammo if I still have some. Also, I plan to bring another AR with me, and swap out its 5.56 BCG out for the range trip for testing, if I need it.
So in my case, my new problem seems to be ammo related but I can’t be sure yet, as I have not had the time to re-test. It’s incredibly frustrating when this happens, which I think is especially frustrating when you build the gun yourself, because then you start second-guessing everything that you did when building it.
I actually also might replace the recoil spring of my CMMG kit, too. I’ve certainly successfully and happily fired a ton of 22LR using this kit, so it might be time to replace the spring anyway.
I could throw more thoughts about this your way, but the whole thing can be pretty maddening. It’s good to try just one thing at a time, if possible.
Good luck with yours. Let me know if there’s anything I can do to help.
Something I forgot to mention: how old or new is your CMMG kit? The ones from four or more or so years ago have a different chamber adapter than the new ones. The older ones were made of a few parts whereas the newer ones are monolithic/one machined piece of metal.
Look at your chamber adapter (the part that inserts into your AR’s chamber): is there a crack/split that goes down the length of the adapter? This is a common problem with the old chamber adapters. These older design will probably have a brass base to the chamber adapter whereas the newer style are all stainless steel.
Please let me know if this helps.
@@radomguy9678i really appreciate the feedback and pointers! You gave me some insight as to what else i might need to look at. Mine jams with any kind of ammo, it is virtually a singleshot. Next i guess is hand polishing everything in and out, trying a different lube, and repthe recoil spring and see what happens. On the plus side it is very accurate; rabbit-head accuracy to 100yds with some brands. Im a helicopter mechanic & Harley mechanic and so far trying to be a CMMG mechanic😅I'm seeing a close relationship between the three:
For each hour of operation, 3 hours of repairs & maintenance are required 😶
And mine is a dedicated upper complete unit, no adapter rqd.
@@stephenembrey883 oh man, I am sorry to hear that you are still having to mess with your conversion kit! But it sounds like you are taking it in stride so that is good.
I know that you replied telling me that you have a dedicated upper. Does that mean that you have an upper that was made for 22lr, and not for .223/5.56?
It is really hard to describe what I am asking about the “chamber adapter.” It is part of the CMMG kit. If you would, please check out the link that I will share below. That is an example of a crack in the chamber adapter. The same thing happened to me when I first bought my conversion kit. It was running great then something broke and it basically became a bolt action gun. I called CMMG and they sent me a new chamber adapter part and it fixed the problem.

Mine is in a normal ar-15 and it is currently stuck and wont come out.
Sorry to hear that. I hope you can get it resolved soon.
@@radomguy9678 AT3 Tactical decided to send me a completely new unit and it works perfectly. ccmg however just wanted to send the part that was sticking in to barrel and it would takes them weeks. So AT3 customer support is great..he even send me an extra magazine for my trouble. I'll be sticking with them from now on. I still may get the kit for the conversion kit to really get it dialed in.
Sorry for this late reply. UA-cam settings held your comment for review (I have no idea why) and I did not know that.
That is some good customer service from AT3! I am glad they helped you out.
I actually have had good customer service from CMMG, by the way, in case you wanted to know. When I first got the kit several years ago, it used to ship with a different kind of chamber adapter. That old chamber adapter sometimes would crack down the middle. Mine did just that. I called CMMG and they sent the new style one out to me right away.
Also, this past summer I dropped one of my CMMG brand mags for the 22LR conversion kit. Usually no big deal but it landed smack on the feed lip (the very top) onto my concrete cellar floor and broke. I called to ask if I could buy a new left side magazine housing from them, as it was my error. They sent me a whole new mag instead, free of charge .
From my own experience, I think you could count on them to help you if you were in a bind, but obviously I cannot guarantee that, since I am just a user of their product, like any other average Joe.
Enjoy your AR, and thanks for the reply!
If i accidentally touch the mag while holding it or resting on the bench, i get failure to feed, do you think this will help it? Probably not, cause its the mag that moves and can't cycle a new one, too much mag play
I don’t think this would help your exact issue, no. However, your problem is not uncommon. People will add some sort of shim to the magazines so that it will fit more securely in the magwell. There is a product by “Catch22” that I have heard of, but not tried myself. It is a shim that creates the good fit for the mag in the magwell, but also allows for using Smith and Wesson M&P 15-22 magazines. However, I cannot confirm if it works when using the CMMG mags.
I find the Black Dog magazines to fit tightly as do others but they do not drop freely for me when pressing the mag release button.
If I were having that issue, I would try shimming the mag with electrical tape, running vertically, until I would find the right fit. The electrical tape may not be a permanent solution but it can help troubleshoot a problem.
I have used JB Weld brand epoxy for things like this, as a permanent solution. If you find that the gun operates properly when the mags are shimmed with a certain amount of electrical tape, you could add a layer of the epoxy to the side of the mag, let it dry, and slowly sand off epoxy material until it is the perfect fit. And it will dry very close to the original mag black color. Of course, try the black electrical tape first to see if shimming fixes the problem.
Good luck! That issue is pretty common, so I think you will be able to fix it without much trouble.
Wow. You got a magazine grip and everything….! Helps with all that recoil. Good idea….
Thanks! The reason I picked it up is because I was not comfortable wrapping my fingers around the handguard with it being so close to the muzzle. I found myself instinctively holding the magwell when shooting it, so I looked for and found the magwell grip that you see in the video. I love the feel of it. It would be really good for close quarters use.
Thanks for your comment!
Those mag grips are trash...avoid them at all costs!
If you are talking about the Chinese knockoffs, I'll agree with you. However, the one that I have in this video is an original made by the Israeli company FAB Defense, and are excellent quality, and very comfortable and useful for me. Chinese companies break copyright laws like mad and make crap imitations to boot. Suckers buy them from Temu and other places.
And it looks like they are a really good price these days. I paid around 45 for mine a number of years ago, directly from their website. Now they are only 22. They are also the original designer and manufacturer of the MOJO magwell / funnel. I am not into the style or the current style of MOJO magwell, but the quality is excellent.
Knockoffs use a cheap plastic and use screws that thread directly into the plastic. FAB Defense uses machine screws that mate with nuts that fit into a mold in the opposite side of the magwell. Again, excellent quality.
@@radomguy9678 i had a FAB defense...it was trash. Fab defense is nid at best....some of their shit is decent, most of their shit is gabbage
Clean it and then put Lee case lube on it. The shells will cycle easily with no jams.
Where have you put the Lee case lube - on the bolt, or inside the upper? I have never heard of that trick but it sounds good.
That’s awesome!
Thank you! It’s really hard to put this thing down once I get to the range!
@@radomguy9678 yea I’ve been checking them out the last few weeks . I wanna scoop one up this was the first I’ve seen about an issue with them though.
@@contractor556 I think you will find that most issues, if any occur, are easily resolved. That’s part of why I believe they are so popular.
@@contractor556 And, the reason why I made this video is because I absolutely love the conversion kit and I know others do as well. I knew that it ran great in my carbine. With the issue that I was having with this pistol, I could not find the solution. Sure, a “Bore Buddy” would likely have solved the issue just the same, but I had never read anywhere that a buffer spring was necessary with the kit, so I did not even consider it at the time (if someone chooses to use a Bore Buddy, the Bore Buddy it takes the place of the buffer, and the buffer spring is needed). Hopefully I explained this well enough in the video anyway. If you do have any questions, I’ll be happy to help if I can.
I hope you can get one of these awesome conversion kits; you won’t regret it!
@@radomguy9678 thanks man! Definitely will be checking it out in the near future and keep ya posted if I “pull the trigger” lol
I am not deaf, but I can almost hear you in this video.
Just an iPhone video, nothing anywhere close to professional audio or video. I am not trying to grow my channel, I don't ask anyone to like or subscribe. I am just a guy trying to share a little knowledge with others who might want to watch and or listen. Hopefully it was useful to you.
Old style CMMC mags, or the newer CMMC mags!
Is that a question? I’m not sure. If you are asking what mags I use, I have the older style as well as a Black Dog brand mag, too.
everybody watching

Bore buddy kit.
I mentioned in the video that the Bore Buddy was an alternative to using the buffer, yes. Bore Buddy makes great products; I have a few of their items.
@@radomguy9678 I saw a unboxing video and it came with a black backstop. That slid in and out of the BCG. Did u get that??
@@lanceculver5900 The video creator that had that probably bought one of Bore Buddy’s “kits” which can have a few items. One can also buy their stuff one item at a time. I believe I bought some items separately from them but I can’t remember. Anyway, I did buy and install that black plastic “buffer” as they call it.
@@lanceculver5900 finishing my comment here, I think that black buffer piece is a good idea and serves its purpose well. I have some handguns that I wish had buffers like that to reduce or even eliminate wear and tear on the frames of those guns.
