The military-chosen Mk13-SD is an ultra-lightweight fast-attach high performance sound and flash suppressor engineered for bolt action rifles chambered in 300 Winchester Magnum and 7.62 x 51 mm.

• Grade 5 Titanium monolithic baffle core and Grade 9 Titanium tube give the Mk13-SD an improbable weight of 15 ounces and the durability to withstand the 300 Win Mag muzzle pressures and temperatures
• Small size and light weight it delivers greater sound reduction and accuracy than any similarly-sized competing model
