DESCRIPTION

APA Fat Tuna Barrel Tuner 3/4x24 Nitride
by American Precision Arms

Product Overview:

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 you’re 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 doesn’t love; the Fat Tuna is your guy.

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.

We recommend cleaning the Fat Tuna system every 200 rounds or between matches. The Fat Tuna only functions on APA muzzle brakes. The Fat Tuna is 1.7” long and 1.73” in diameter. Can accept barrel contours up to 1.25"

The adjustable weight is 5.3oz and uses a 3/32 Allen key wrench.
