Little Tuna Barrel Tuners
by American Precision Arms

Product Overview:
The APA Little Tuna is a product of a partnership between APA and Adaptive Tuning Systems (ATS). This tuning device attaches directly to the APA Little 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 Little Tuna is your guy.
