Description

Tuna Cans BackFin – XL (12-Baffle) — Hybrid 17-4 / 7075 | 1.625″ OD | .375 Bore – Affordable Silencer

The Tuna Cans BackFin – XL is the longest BackFin option for shooters who want maximum internal volume and the most baffle stack while still keeping weight down. It’s a dedicated suppressor for .300 Blackout and 8.6 Blackout, built to run hard without turning your rifle into a boat anchor.

Up front, it features a large 3″ blast chamber made from heat-treated 17-4 stainless steel, plus a heat-treated 17-4 stainless first blast baffle—built to take the highest heat and pressure where it matters most. The remaining baffles and the end cap are made from aero-grade 7075 aluminum, saving weight while maintaining durability.

With a .375 bore and 1.625″ OD, the BackFin – XL delivers strong performance in a lightweight, tough package.

Important: This suppressor has a .375 bore and cannot be used with 9mm (bore is too small).
