You will be surprised how many people don’t know how to do this. Good video
I never realized that an untimed muzzle device doesn’t need a crush washer or a lock nut. New learning!
Lamar is a natural in front of the camera, I hope y'all pay him well enough.
For those about to comment on ft/lbs and why a suggested amount of tension isn't stated, here's something to think about. Firstly, for those who just want a magic number.. its usually around 15 ft/lbs... However, the torque of a standard muzzle device which either requires timing and/or a crush washer would be dictated largely by the crush washer's material, and/or the material of the muzzle device or barrel and so giving a standard isn't particularly viable. What might work well for one device, will ruin another; and thus giving any form of specificity would have to be case by case. If that doesn't make sense, I'll elaborate by example. If your muzzle device/flash hider is made of aluminum, but the barrel is steel, then you could easily strips the aluminum threads. The same is true with stainless vs steel
*What do we want?*
Folding Stock Adapters/Take Down Barrels/and Suppressors!
*When do we want them?*
Your earliest convenience. =D
Thank you so much. I was pretty nervous about breaking off the index pin on my new BCA barrel while changing out the flash hider. I feel more confident about moving forward now. Many thanks.
Man, the muzzle device on the 458 I got from you guys defietly didnt want to come off!!! Well made! A torch helped it loosen up. Thanks for everything bear creek, you guys rule
You guys perfectly torqued your flash hider (with crush washer btw) on a 6.5 Grendel upper I got from you. It was on snug, but I was able to hold the barrel with one hand and remove the flash hider with a wrench with a bit of effort. I put a thread protector on the front and now I'm ready to hunt with it. Your products and attention to quality always impress.
For some reason I can’t remove the A2 flash hider on my upper it’s so damm tight
Did you get it off?
@@alepepperoni2563 I can't get mine off either
@@tdq6449 If you don't have access to a longer handled wrench or a long breaker bar, go to the hardware store and buy a two-foot long piece of PVC pipe with an internal diameter large enough for the handle of whatever SOCKET wrench you own to slide into it (use a standard socket wrench instead of an armorer's wrench). The PVC pipe diameter should be the smallest you can find that will still allow the wrench handle to fit inside it. Also purchase a (open end) crows-foot spanner that will fit your socket wrench (either 1/2 or 3/8 drive); typical A2 flash hiders use a 3/4" size spanner, but measure your flash hider to be sure. Attach the crows-foot spanner to the socket wrench, put the spanner on the flash hider flats, slide the wrench handle into the PVC section enough so it won't slide off under load, and give it a counterclockwise turn. Be sure to push on the PVC pipe "handle" at a point farthest from the barrel. You're basically creating a longer moment arm, which greatly increases your mechanical advantage. With a long enough handle, you'll be surprised at how easy it is to remove the device, assuming no heat-resistant thread locker was applied during installation.

Great video, didn't know it needed timed!!! Thank you and keep up the great videos. 👍👍👍
Great video. Thanks
Great info!
Thank you I am planning to change mine. To bear creek a2s
MM77 👍🏼👍🏼 Approved
Where did you get that Apple Watch case. Looks really cool
Some muzzle devices do have to be timed using timing washers or shims.
Easy Peasy Lemon Squeezy
Can you post a video of how to install a chainsaw bayonet? I saw one on the TV and it looks badass.
Do I need a new crush washer for a blast diverter on saint victor rifle?
No ft/lbs recommended on the torque ?
Also, if using for a suppressor, do not use crush washer.
Would you be interested in manufacturing a four prong flash hider?? Are used to be able to get a four prong flash hider on eBay from YHM. And they work great. I would also be interested in testing of your spiral Flash hider against a four prong flash hider to see which one is better. If your spiral flash hider turns out to be better I will have no problem purchasing multiples of those. Thank you for your time.
I just had my muzzle replaced on AR-15 SBR how long do I have to wait to shoot it?
Great vid Lamar but you do know somebody will call you out on torque.😁
What device are you using to vice the upper?
I have a right charging 308 upper with one of the "spiral" flash hiders. My armorer's wrench doesn't fit, and the flash hider is too big for the wrench. What size wrench do I need to remove it? Also is there any thread compound on it?
Man, I love my upper but damn it these flash hiders are on WAY too tight! I put heat on it w a torch and a wrench w my 170lbs on it and nothing. Any ideas how to get it off.
Same here. Spiral on brand new .22 upper, have never ever had one stick so bad. heated twice, soaked overnight. Stupid to tourqe down so hard. It’s a .22 not a .50!
I actually had mine sent back to the company for free and they got it lose for me. Took about a week all in all. Not bad. Shouldn't have been on so tight in the first place but all is good now. Thanks Bear Creek. I would like to see new side charging knobs. Extended and or different shaped... Just saying. 😁🙄

Crush washer….cone facing forward or facing shooter?
Which direction should crusher face?
So is it ok to do this with the receiver vise block as you do here? I was told its better to clamp the barrel to keep from putting pressure on the barrel nut as you tighten or loosen. Thanks for your help.
Yes, it's better to clamp the barrel, assuming you can safely and effectively do so. Securing the receiver when torquing a muzzle device means you put rotational forces on the takedown/pivot pin holes and risk exerting a shear force on the barrel index pin. That said, because thing A is better than thing B doesn't mean thing B is bad. In this case, if the torque applied to the muzzle device is relatively low, so is the danger of damage to the receiver. The vise blocks that have both an upper piece and a lower piece (one on the top of the receiver and one on the bottom; the sandwiched receiver is placed in the vise 90 degrees sideways and the vise jaws clamp on the two vise block pieces, squeezing the receiver in place) distribute the forces better than using only one on the bottom of the receiver like you see in this video.
I have a complete 450 bushmaster upper from you guys. Do you use rockset on the muzzle device?
No we do not flash hiders are threaded onto the barrel
Any suggestions on removing a stubborn spiral hider on a brand new bca .22? I’ve removed muzzle devices for years and have never had one on this tight. It seems like a lot of guys are having a tough time with the bca .22 upper hiders being put on in god mode at the factory. Any suggestions appreacated
I can't get mine off either
Dead air break for my 6.5 Grendel better than flash hider stock.
Question does the spiral flash hider have any advantage over your a2 hider?.
No significant advantages other than aesthetics and that it doesn't need to be timed
Ordered a 16" white cerakote 5.56 barrel and cannot get the flash hider off at all. It is TIGHT! Is there rockset or anything on them?
Were you able to get it off?
Do you guys use any glue or adhesives to put on your flash hiders from your factory? I wanna change mine out that I bought from you and it’s on there good. Just wondering if I will have to lightly heat it due to glue or loctite.
Fr I can’t even remove mine lol
@@Jstk209 i got mine off. It was a pain. I used a vise with soft jaws,
Extended handle open ended wrench,
and a heat gun on low. It took some cranking but an AR upper receiver vise block would be awesome and super helpful if you have one. My 12.7x42 upper is awesome from them.
didn’t sure which way to put the crush washer on the only question I have is yet again not answered.
Good job, now can you show us how to change the barrel on your uppers?
Coming soon
What is the performance difference in the standard and spiral flash hider, is one better ?
i have both and i notice less muzzle rise on my A2 style. the spiral is a lil more violent(in 5.56 feel) so while its not a ton it is a noticeable difference. the spiral just looks kinda cool lol. havnt really done night work with it to verify muzzle flash though.
Umm, not complaining but the last upper I purchased from B C the m d was finger tight, I always dissemble, clean and lube new pews and parts and I was able to remove the m d with a simple twist of the m d with my hand. Other than this little inside the shop oversight the upper has worked perfectly and no complaints. And as I said I'm not complaining or even venting, just wanted to let you know. thanks
Sorry to hear that. We always value and consider customers' feedback
Heat the device that you want to remove with a small torch. Not to red hot but just a few minutes.
It will come off.
I have a 556 complete upper from you guys and they muzzle device is not budging, is this normal?
Me too. Also...can't remove the hand guard to get to the squared sides of the break
@@dereksexton4199 not sure which upper you have, but I have the 625N and it has 8 torx head bolts that connect the hand guard to the barrel nut, after I remove those it slides right off
@@ledwire3784 I have a Gen 1, 7.5" pistol upper. Has 6 hex head screws. Can't budge the guard, afraid I'll really screw something up...like the gas block or barrel threads. Already tweaked the A2 break today
I've got two BCA complete uppers, both came with spiral flash hiders that are IMPOSSIBLE to remove. Are they red Loctite glued in or was Rocksett used??
Sorry to hear that, we do not use Loctite on any of our builds. Please contact bcatech@bearcreekarsenal.com for assistance with removing your flash fider.
@@Bear_Creek_Arsenal I finally managed to get both flash hiders off by clamping the bbls in a vise with leather padding and using an AR wrench tool.
@@rfdsrd you wasn’t using a vice at first ?
@@Pray_Grind Put in a receiver vise. What worked was putting the bbl itself in leather padded vise.
Yea my .300 blackout muzzle device won’t budge you guys put it on so tight it’s cracked
Spiral flash hider is definitely not 19. Unlesss bear creek installed the wrong one on my upper
I’ve got your 12.7x42 and I’m having an helluva time replacing the muzzle device, does it have Rocksett on it
Sorry to hear that; please reach out to bcatech@bearcreekarsenal.com for a detailed response on how to handle that
I am having a similar issue on a .458 upper.
Thanks, I got the 24mm wrench and with a strong 💪🏾 pull in my vice it came right off
@@andy1147 get a 24mm open end wrench 🔧 put in a vice it should come right off, that’s what I did
@@MrRoro256 That worked!
The second flash hider on my bca 10.5 I tried taking it off today and I couldn’t it’s really on there any suggestions?

@@blueeyeddevil1 I got it off thanks
Does an adjustable gas block void the warranty?
It does not void the warranty, find out more about our warranty under About Us on our website
@@Bear_Creek_Arsenal Thank you!
@@Bear_Creek_Arsenal Is that not modifying the product?
What voids my Bear Den Guarantee?
Cutting, modifying, or misuse of a BCA product
Having another manufacturer or gunsmith work on a BCA product
Damage caused by using high velocity or high-pressure ammunition, tracer ammunition, or hand-loaded ammunition
Normal wear and tear
Do NOT exceed 15 to 20 ft lbs on a muzzle device, you will begin to deform your actual barrel diameter. The more you know....
It would be awesome if you’d stop talking and just do it
why remove the handguard?
Access for the wrench.
