The Sportsman Ultra Light HD .300 is a lightweight durable suppressor designed by hunters for hunters. Full 17-4 Stainless Steel construction brings a new paradigm of durability to the Sportsman Ultra Light family of suppressors hence the HD (High Durability) designation. Tubeless laser-welding a silencer technology pioneered by Griffin affords near-titanium weights using much more durable 17-4 H900 heat-treated stainless steel. The original Sportsman Ultra Light Suppressors were aluminum in construction and had to be relegated to sporting use only allowing a handful of rounds to be fired in quick succession then allowed to cool. The Sportsman Ultra Light HD™ series does away with these restrictions providing of peace of mind to hunters knowing their suppressor can handle whatever they throw at it. This added durability allows end users to dial in their hunting rifles without needing to break for suppressor cooling as was the case with the previous aluminum Sportsman suppressors.
