The Griffin Armament Optimus Silencer is a modular design that is highly versatile and can be used on firearms from 17HMR all the way up to 300 Winchester Magnum. The Optimus Suppressor features a full 17-4 PH stainless steel construction with removable stacked baffles for ease of cleaning and re-configuring. The standard configuration is 9.4”, 18.5 oz., and uses a taper mount for attaching to your 300 Win Mag. A simple re-configuration and it is lighter, shorter, and ready for your 308 rifle. Yet it doesn’t stop there, throw it on the 9mm booster piston and it will work on your favorite semi-automatic 9mm pistol. An included 3-Lug assembly is perfect for mounting on your 5.56 carbine and the .22 caliber endcaps keeps your 10/22 as quiet as can be.
