The Griffin Sportsman Ultra Light HD .36 multi-cal suppressor is a .36 caliber can that runs on everything from a 9mm carbine to a .338 Lapua Magnum rifle (brand part no. GASUL36HD-W). Griffin Armament builds it from 17-4 H900 heat-treated stainless steel using a tubeless laser-welded design. The HD build replaced the aluminum of earlier Sportsman cans, which had to cool after a handful of rounds. ECO-FLOW baffles reduce the gas that reaches the shooter. A 1.375×24 HUB rear thread accepts Griffin and third-party adapters, and Nielson boosters put it on 9mm tilt-barrel pistols.
