The Griffin Armament Sportsman Ultra Light HD .46 in black is a big-bore hunting suppressor with full 17-4 stainless steel construction (brand part no. GASUL46HD-W). Tubeless laser-welding gives it near-titanium weight, while the HD for high durability means it does not need to cool between quick shots like the older aluminum Sportsman cans. Patented ECO-FLOW baffles reduce gas exposure for the shooter. Lever-gun hunters and .45 caliber pistol owners are the natural fit.
