I’ve probably watched every UA-cam video on PWS rifles and read through many forums, not one mentioned the POF roller cam pin mod. I appreciate it 👍
Running all PWS myself. Did not know about the roller cam pin issue. very useful
I really respect that disclosure at the beginning, I have ordered my rifle and have the rolling cam all ready for it, thanks
I also have been converted to PWS after owning several other piston driven guns. Mainly because I run most of my fire arms suppressed. I have 5 different PWS uppers that are all suppressed and have the POF roller cam pin in all. Two uppers are with PWS lowers but the l do enjoy the RADIAN lowers. Good video and good advise.
I’d definitely like to add another PWS to my inventory eventually.
Hey can i run a dead air sandman s on this? I was looking at sig mcx virtus but i was hearing the barrel has a weird taper or something that could make running your fav supressor more complicated.
This roller cam pin is just basic or something else from POF?
@@pd5156 it is from POF.
Just purchased MK111 Mod2. Haven’t shot it yet cuz of current shortage. Blessing in disguise as I wasn’t aware of cam pin excessive wear. Will buy POF ASAP. Thank you for the pro tip (pun intended)! 👍👏🤜🤛
PwS is awesome. I have a mk1 mod 1 and it came with an out of spec cam pin that would not go back into the bcg. Contacted customer support and they shipped me a new cam pin and brand new bcg
I was having the same marking/ gouging on the upper receiver as well. I thought it was from being over gases from being on the wrong setting. Glad to know that I'm not the only one, but i swapped to a Lantac cam pin and fixed the issue as well.
My MK116 from PWS has been flawless. Good video
Perfect video timing just started thinking about wanting to pick one up but havent seen that many videos on the mk111 from people i watch
Just snagged one of the last mk111 pro uppers from pws at stellar price, I’ll be ordering that cam pin aswell from POF. Appreciate the quality video and insight. I’m forced to shoot shouldered weapons lefty (due to vision)so long stroke piston seemed to be my best option. Excited to start training with this setup.
It will definitely be nicer than a DI gun for you
Love my PWS MK111 Pro Upper. Once I get around to getting a can, it’ll be my dedicated suppressed/home defense rifle…👍👍
Love my MK111 Mod 2 and BRN-180S
Thanks. I just caught this upper on sale and I’m buying that roller cam pin
Thank you so much for doing this video. It was very well done and very informative. It is probably the best one that I have seen so far on the PWS. I was already leaning this direction as a dedicated, suppressor host but I really liked the way that you present.
Happy to see another PWS review! I thought I new everything, but just found Primary Weapons a few years ago. I have a MK114 MOD 2 and recently bought a MK111 PRO. The mk114 ran perfectly, even with cheap Russian TULA steel case, and my MK111 pro needed some break in, and gas settings set to maximum gas, and heavy lubrication. Now it has 300 rounds and runs reliably. I just bought a used Liberty Constitution and haven't made a video yet, but glad to see someone else into these too. I love them! Much lighter than LWRC and HK416. Great gun, but has a Tavor or Mini 14 recoil feel. I'm running an ArmaSpec recoil spring. Milspec trigger. I might try a WOT trigger, but not sure this PWS ships with a FA BCG. Great review. Join us at Black Rifle League if you come up to Seattle. Keep up the good work, quality reviews!
I’m glad I found this video for that pof rolling cam pin because I took a look and noticed it now will it be fine even though I do have a scar no material was taking out but some of the paint is missing
I messed up big time. These were 1k a few months ago, now they're 1400. I was going to get my first AR, these were out if stock so I went with the Zion 12.5 instead. Still a decent pistol, but I'm kicking myself now wishing I waited for these to come back in stock.
I was in a similar situation lol, I really wanted the Zion pistol 12.5” but couldn’t find one in stock anywhere. Ended up finding a mk111 mod2 locally and snagged it for under 1500. Couldn’t be happier, it’s a phenomenal weapon. Stay on top of your search and get one when you can, they’re worth it.
As always, great content 😎💯
I appreciate it!
I did a double take on that Spanish, “Am I on the same video”. Gracias por el video.
De nada. Estoy aprendiendo español un otra vez. Yo practico con mi compañero a mi trabajo.
I lucked out and got an upper with the yhm flash hider and a qd point off Reddit. All shipped for $650. Can’t wait to shoot it. Still waiting for turbo k sadly.
They make a pro m model that has a forward assist I think that’s what id go with
Love my Mod2.
I turned my front sight backwards and it's more streamline. But similarities with the gas settings
New vid dropped just in time for my lunch break. Perfect timing brotha!
It was meant to be!
POF roller cam pin.
Did I suggest that during your 762x39 Diablo video?
I have been using the POF pins in my PWS uppers as well.
Regardless; glad to hear the PWS fans in your circle are using them.
Secondly: I suggested to Tim at MAC;( after he complained about PWS reassembly) that he simply turn the upper upside down. ( He is such a Sig fan, I think he poo poos everything else)
I think he had just never done it before rolling the camera on it
How are you liking the Pws in 7.62?
@@jesusm4656 It is my opinion that the Mk111 mod2 in 762x39, along with the 20/28 round Cproducts/Duramags; is the best 762x39 platform on the market.
I believe Sage Dynamics and Klayco 47 will agree.
New subscriber here. Love the videos. Have a question. I just got the mk111 pro upper and I’m confused on the pof cam pin, will it just drop in the bcg because PWS states that it will not. Thanks for the help.
a Mid-length as gas system is always recommended over carbine. Is this also true for piston systems?
I had a POF and it broke. Got rid of it and went straight to BCM. Never looked back. I want a gun that’s reliable and all the parts are easily replaced. Proprietary products aren’t my thing. Until piston gains more market share, not for me.
Totally get the going back to common parts. What exactly broke on your pof?
I forgot what it is called. The piece at the gas block/piston that regulates the gas. It broke, which required me to manually cycle it. Pretty lame. POF sent a replacement free of charge, but I got rid of it immediately. Can’t trust my life on it.
If you go piston I’d stick with PWS or Lwrc. I’ve had 0 issues out of both and they’re amazing performers.
i would love to have a piston ar but i'm a poor. awesome review. really don't see many reviews on the pws uppers.
Thanks, I’m getting me an upper, your review was exhilarating
I would have been nice if you compared the gassiness experience to other uppers you've tried. Still not sure about this as a suppressor host.
I have two PWS pros now. A mk111 and a Mk116. Is there any reason to get the mod 2? the mk116 pro is a little on the heavy side.
Hey man great video as always. I have a Mk111 mod 1 and it’s been phenomenal. I also switched out the cam pin for the POF roller. I read online recently that sometime in mid to late 2020 PWS switched their barrel material from 416R to 4150cmv. The guy had images from his emails with PWS so I guess it’s true, I was just curious if you could confirm? My upper was made in 2021 so I’m pretty sure it has 4150 but I thought since I’ve had it it was 416R lol
I couldn’t tell you what steel they’re using
Did you do any modifications to allow proper installation of the POF roller?
@@evano597 no modification is needed
Did the kurz mount really make it that much louder or did I just misinterpret what I heard when you changed from the traditional mount to the kurz mount?
Did the Geissele charging handle make a big difference in mitigating blowback?
In my experience, yes
This or bren 2 for a suppressor host. You gotta pick
Bren 2
Is the gas still pretty bad with the PWS upper when running it fast? It looks like you are still getting some significant gas. I am considering the same suppressor for my MK111 build, and I'm curious if you would recommend it. I am also looking at the OSS, but the YHM definitely has the value for price, and I was hoping the suppressed setting would provide relief.
Oh man please do a review on the POF 415 Edge 10.5 if you ever get the opportunity!
Is there a point to running a piston upper if you aren’t going to suppress it?
Yes. Runs a lot cleaner.
Reliable and runs cleaner. At most wipe with a paper towel or oil rag and oil it. Suppress for the future if possible?
Good video. Question. Have you tried a H buffer? Its 3.8 oz.
Great intelligence. Did you have to install the modified gas key? Respect...
The bolt carrier is as it came from the factory other than the rolling cam pin
Did you cover up the venting holes on the bottom of the gas tube before spray painting the upper?
I did not
I've been wanting to get this upper for quite some time now but it's either out of stock when I have the money or it's in stock when I don't have the money (thanks covid). Just out of curiosity, how come you can't use a bolt from another company? Seems like all you would have to do is just take off the gas rings.
The tail of the bolt itself is a different shape and without a spring to help reset the bolt, the system wouldn’t work properly.
@@OreGear I wondered if that might be the issue. Hope those bolts are good. I just looked at their website and I couldn't find any spare bolts for sale.
Was that a shot at MAC? lol
I have no idea what you’re talking about 😉
I love my PWS setups, they make great suppressor host. Recently picked up a Mod 1 MK107 and just added the Law Tactical folder adapter, have not tested it. I have heard that some PWS pistols and rifles may require the MODIFIED BOLT CARRIER EXTENSION GEN 3-M FOR PWS… Do you have any insight on that?
I believe they changed their carrier awhile back to avoid that. I think it was a smaller hole at the rear of the carrier. My law folder worked perfectly without the modified extention
How did you put the pof roller cam pin? Did u removed the gas key?
Nope. The POF Roller Cam Pin just drops in. Might be a tight fit, but it’ll go
Okay thanks, one more question. I have 2 kinds of pof roller cam pin here, the first one have a bigger roller and the other one is smaller roller like size of the body of the cam pin.
I’m not sure. I didn’t realize there were different sizes. I’ll try to find out which style we carry when I get into work tomorrow
@@michaelignacio752 The smaller one. One is for .308 and one is for .223/5.56. 🤙
I just installed mine, mine just slid right in. I did no modifications on it, is that fine? And what buffer weight and spring did u use?
Weird they made it a 11.85 wonder if there’s any velocity boost from that. They have it listed on there website but nobody else has tested it that I’ve seen and who knows if that’s accurate on there website.
For some European law or something.
how would u compare the recoil to a mid length? really debating getting one of these uppers or a noveske for a shtf rifle
It’s going to depend on your specific setup, the ammo you’re shooting and the gas setting you’re using.
Does this need a buffer tube? If i wanted to put a MCX style folding stock on this could i add that on?
Yes it requires a buffer tube
@@OreGear damnnn... bummer for my use case. Still an awesome weapon though. Thanks for replying.
Do you know if PWS uppers work on any AR15 lower receiver? I've been looking at getting a PWS upper but don't wanna have to a whole new lower.
They’ll work with any mil spec dimensioned lower
Just wondering if you used your oss 556k on this upper yet. If so, how was it
I don't own an OSS so I'm unable to test one on this upper. The OSS I tested was from SilencerShop.
optic and iron sights?
Yes
@@OreGear what iron sights and primary arms optic are you running on this setup
Do you think a pws upper would be to front heavy for a kp 15 lower? I might go for a 14.5 pws upper and a kp 15 lower
I don’t think so. Not much more so than a “standard” upper
@@OreGear thanks
It’s front heavy when you put a can on it.
Would you recommend pof cam pin for mod2 model?
Yes
@@OreGear thanks
Can you put the upper on any lower right
Any mil-spec lower in accordance with the NFA
Lol shuould have gotten mod 1 so you get the forward as
What front sight is that?
It’s the PEQ15 front sight from Midwest Industries. You can use the code “OREGONTRAIL” for 10% off
@@OreGear thanks bud.
Holy white legs Batman!
Welcome to Oregon
Radian charging handles are nice but geissele's is definitely better, with the DD grip n rip in a close 2nd
I’ve never used one of the DD handles beyond dry handling them off the wall at the store
hmmm
No longer an ar guy. But it's not right to not watch your videos. So go ham my man
I'm sure there's somekind of surgery u can get done these days to have that reversed, but no judgment here my friend 😬😉
😊🇺🇸🍺🔥
Boring
