Griffin Checkmate HD

Details

Due to popularity of Griffin's CHECKMATE-QD suppressor, Griffin now presents to you the CHECKMATE-HD™ suppressor. This new CHECKMATE-HD™ is a 5.8 ounce, 5.7x28 pistol rated rimfire suppressor and utilizes ECO-FLOW™ baffle technology as well as the newly developed CARBON-GARD™ technology. The 5.8 ounce, 5.04" overall length suppressor features a 17- 4 heat treated ECO-FLOW™ baffle system, front cap, and integrated EZ-LOK™ QD mounting system. The tube is 7075-T6 billet machined aluminum and hardcoat anodized for maximum strength.

The CARBON-GARD™ technology seals the entire baffle core with high temperature Silicone O-rings which allows the suppressor to be more user maintenance friendly. After 2000 rounds are fired, the inside diameter of the tube and outside diameter of the core are still spotlessly clean for ease of disassembly without specialized tools other than a US quarter.

Extensive workup was done to the baffle system resulting in a baffle system with zero first round pop and a market leading sound pressure level (SPL) on rifles and pistols.

The CHECKMATE-HD™ comes with an EZ-LOK™ 1/2x28 barrel adapter and is field ready out of the box. The only supporting accessory outside of various threaded barrel end couplers, is a CAM-LOK® rear mount, making this suppressor very simple and straightforward for end users to understand and utilize. Unbeatable sound performance, unparalleled ease of maintenance and servicing, light weight, high strength, historically accurate CHECKMATE-QD mounting, and incredibly competitive pricing are the user benefits of the CHECKMATE-HD™ suppressor.
