The Tuna Cans BackFin (6-Baffle) is built for shooters who want a suppressor that's lightweight, crazy strong, and purpose-built for .300 Blackout and 8.6 Blackout. This is a dedicated BackFin can designed to handle hard use while keeping weight down-perfect for setups where balance matters. Up front, it features a large 3 blast chamber made from heat-treated 17-4 stainless steel, along with a heat-treated 17-4 stainless first blast baffle-built to take the hottest, harshest pressure and erosion where it matters most. The remaining baffles and the end cap are made from aero-grade 7075 aluminum, saving weight while maintaining strength and durability. With a .375 bore, 1.625 OD, and a compact 6.75 length, the 300BackFin delivers big performance in a lightweight package-coming in at just 10 oz.
