This Muzzle break makes a statement on the end of your rifle and it is easy to remove and switch for a Suppressor.

Nice brake


finish and machining are excellent. Definitely reduces recoil and muzzle rise, without having a stupendous "bark" worth every cent!

Cool factor of "off the chain"


I am building a .300 Blackout upper for my AR and I already have the YHM 5.56 slant muzzle brake. It works so well and looks so good that I wanted the same for my .300. The cool factor is off the chain. Primary Arms always has just what I want at great prices and always provides me with outstanding customer service. Why would I shop anywhere else?I am a customer for life!

Slant brake


i have not had a chance to use the muzzle brake yet but build quality looks very good

muzzle brake shipping


Muzzle brake is great finish is good. Shipping by USPS sucked. Why can't UPS ship cheaper. My part needed to go 60 miles northeast of Primary Arms. It went to Dallas, then north Houston, Then to Baytown 25 miles away, Then back to north Houston, Then to Oklahoma City, before going to North Houston and finally to Dayton. 2 weeks. One week in to this ordeal I ordered a part from CA that got here before this order. USPS should not be the primary provider.

Follow up to "Cool factor off the cain"


Finished the .300 Blackout build with this muzzle brake and the YHM .300 fluted barrel and test fired the rifle. Once again everything was as expected. Fit and finish are good but I did have to use a shim for proper alignment (not a negative just something to be aware of). Felt recoil is almost not felt and follow up shots are easily on target. Price quality and Primary Arms super fast shipping are the perfect combination to keep me as a customer.

Tamed the Savage Beast

I installed this on a PA10 in 308 that was kicking my rump with recoil making follow up shots a pain. After install the beast has a gentle bump and is still on target and ready for round 2. Fit and finish are excellent and while the rifle is a bit louder it doesn't have the uncomfortable BARK that so many brakes do. Highly recommend this muzzle brake.

Exactly what I was looking for.

I put this on my bushmaster BR-308. Looks really nice and did allot for the recoil and muzzle rise. I did have to buy a shim kit to get the timing right but no big deal. The way it looks when you get it on there is worth the little extra for the shim kit.
