Product Info for American Precision Arms APA Fat Tuna Muzzle Brake

The APA Fat Tuna is a product of a partnership between APA and Adaptive Tuning Systems (ATS). This tuning device attaches directly to the APA Fat Bastard. Simply replace your existing jam nut with the Tuna nut and youre ready to start finding the node your ammo wants. Whether your barrel is speeding up post break-in or temperature swings have influenced your load at a match. Or maybe you really just want to shoot a specific factory ammo that your gun doesnt love; the Fat Tuna is your guy.image

The geometry used on the front end of the Fat Tuna is specifically designed to counteract the blast flow of the Fat Bastard port. The initial gas flow that has already generated the directional force to reduce recoil is redirected, creating a gaseous shield reducing sound waves and percussive energy. This dramatically reduces the concussion to the shooter without sacrificing recoil reduction. No more brake flinch.
