The Tuna Cans 5.56 - L is the longer, higher-capacity version of our hard-use 5.56 can-built in the same in-house Texas style with the same heat-treated 17-4 stainless steel toughness. It's designed for shooters who want more baffles, more volume, and more performance, without paying a premium price. Inside, the L model runs a 9-baffle stack with ribbed baffles to increase turbulence through the chambers. The threaded baffle system means each baffle screws together, creating a strong, serviceable stack that's built to run.
