.30 Cal AR15?  Not a problem with this aggressive Muzzle Brake/Compensator

With greater caliber comes greater recoil – whether you’re shooting a .300 BLK AR15 or a .308 WIN AR10, .30 caliber is a lot different than standard 5.56.  So, you might consider something more aggressive to help reduce recoil and stay on target.  Similar to more expensive designs on the market, this 3-port muzzle brake/compensator does the same job as many 3-port brakes – dispersing recoil and muzzle blast to either side of the shooter, reducing recoil going into the shooter’s shoulder.  It also compensates through three angled ports in the top of the device, which counteracts recoil by subtly pulling the rifle forward, and pushing it downward.  The result is a device that diminishes muzzle flip and overall force for the shooter, leaving only the momentum of the bolt carrier to deal with.

It’s a great US-made product, includes a crush washer, and is backed by the AT3 Lifetime Warranty.

Outstanding product

Test fired the new build today. .300 Blackout pistol, 8.5” barrel. I’m amazed how little muzzle rise there is. It damn near non-existent. Not to mention it looks as good as it performs.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.

So good!

Folks told me a 7.62 x 39 round generates double the recoil of a 5.56 x 45. With this fixture the recoil is actually less. The noise is also less. So - after reading what independent sources said, I made a very good $30.00 decision. Most other brakes fall short.

Hi there, thank you for your review! We're so glad to hear that our AT3 AR-15 3-Port Muzzle Brake has exceeded your expectations and helped reduce recoil and noise. We strive to provide high-quality products at an affordable price, and we're thrilled to hear that it was a good decision for you. Thank you for choosing AT3 Tactical!

Fixed my accuracy problem.

Might sound strange but I was prepared to make two changes to my 6.8 SPC to see if I could improve the accuracy. Change the muzzle brake and change the bolt. It wasn’t necessary to change the bolt, this muzzle brake has apparently fixed the problem. Very pleased and highly recommend. Warning: It is loud!
