The Griffin Armament Sportsman Ultra Light HD(TM) .300 is a lightweight, durable suppressor designed specifically for hunters using rifles up to .300 RUM. Its full 17-4 H900 heat-treated stainless steel construction brings high durability to a suppressor weighing just 10 ounces. Griffin's tubeless laser-welded design provides near-titanium weight while using a high-strength, high-temperature, corrosion-resistant stainless steel construction. The Sportsman Ultra Light HD(TM) series is designed to handle sustained use beyond the limitations of the earlier aluminum Sportsman Ultra Light suppressors. This added durability allows hunters to dial in their rifles without stopping for suppressor cooling. Griffin's patented ECO-FLOW(TM) baffle system is designed to reduce gas blowback and user exposure to toxic gases while decreasing system gas on gas-operated hosts.
