Available for the first time to the civilian market for 2011, the 300-SD is an ultra-light-weight, fast-attach, high performance sound and flash suppressor for bolt action rifles chambered in 7.62mm NATO and .300 Winchester Magnum. The Grade 5 Titanium monolithic baffle core and Grade 9 Titanium tube give the 300-SD an improbable weight of 13.9 ounces and the durability to withstand the pressures and temperatures found at the muzzle of 300 Winchester Magnum rifles. Despite its small size and light-weight, the 300-SD delivers greater sound reduction than any similarly sized competing models due to the advanced design of the Hyposone® Technology baffle core.
