The CHECKMATE-AM22 Silencer is a heavy duty .22cal suppressor constructed from Griffin s proprietary Nickel 625X powder alloy, utilizing state-of-the-art DMLS additive manufacturing technology. The EZ-LOK mounting system is integrated into the rear of the suppressor ensuring solid lockup and positive retention to the host firearm, minimizing the risk of a baffle strike vs. direct thread suppressors. Included with the suppressor is a 1/2 28 TPI EZ-LOK barrel adapter, which is installed to the host firearm barrel using 22ft/lbs of torque creating a quick mounting, universal thread pitch across all of your host platforms. The proprietary Nickel 625X alloy showed in testing a ~68% increase in yield and tensile strength at 1200F over INCONEL 625, a commonly used suppressor alloy. This advanced material makes these silencers rated for 5.7 28, 22-250, and even .223 Remington on 16 or longer barrels.
