Tuna Cans FAT9 – L 9mm Silencer (9-Baffle) — 7075 Aluminum | 1.625″ OD | .399 Bore – Affordable Silencer

The Tuna Cans FAT9 – L is the longer, higher-capacity version of the FAT9 platform—built for shooters who want more baffles and more internal volume, while keeping the suppressor lightweight and easy to run. Machined from aero-grade 7075 aluminum, it balances strength with low weight for pistol and PCC setups.

With a 3” blaster chamber that can hold big mounts like TRI lugs and piston boosters and a .399 bore, 1.625″ OD, and a 9-baffle stack, the FAT9 – L is tuned for consistent 9mm performance in a compact package. At 8.5 inches and 10 oz, it adds suppression potential without turning your setup into a front-heavy brick.
