The Tuna Cans 40 Cal / 10mm - XL is the biggest version of our hard-use .450-bore lineup-built for shooters who want maximum baffles, maximum volume, and maximum strength without paying a premium price. Made in-house in our Texas warehouse from heat-treated 17-4 stainless steel, this is a serious can designed for high round counts and hard use. The XL model features a 12-baffle stack with ribbed baffles to increase internal turbulence for strong performance and consistency. The threaded baffle system means each baffle screws together, creating a solid, serviceable stack that's built to last. Up front, the suppressor includes a large 3 blast chamber, allowing it to accept HUB mounts and large mounting systems that use standard TPI threading (we recommend the Tuna Can "1-Piece" Mount).
