Extreme Recoil Reduction at an Affordable Price

Taming the recoil of 5.56 tends to be a pretty easy feat – but this muzzle device all but eliminates recoil with an aggressive design to keep you 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.

Exactly what i wanted, big flash with no recoil. Perfect for heavy barrels.

Better than expected

Very happy with it, build well and works great. Almost no recoil but makes the gun very loud and has a lot of flash. Just what I was looking for

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

Great muzzle device

This is a great muzzle device. Not only performs well but also looks nice.

This baby was very nice. It made a noticeable impact on the felt recoil. No excessive muzzle flash or crazy increase in noise. It made it to where I could only feel the buffer spring movement as opposed to the normal recoil.

Great Muzzle Brake

I purchased 2 of these to swap out the flash hiders on my AR's and I can honestly say it was a huge improvement on recoil, style, and loudness of both rifles. For the price you can't go wrong. Installation was simple and took 2 minutes. AT3 is the best hands down for all your firearm needs!
