Griffin Armament Checkmate‑HD — Compact Rimfire Suppressor (BBL 1/2×28)
Meet the all‑new Checkmate‑HD, Griffin Armament’s most refined rimfire suppressor yet. Lightweight and QD-ready, it delivers near-zero first-round pop, easy maintenance, and industry-leading sound suppression in a sleek 5.04" package.
Key Features
-
Extremely Low‑Profile & Lightweight — Weighs just 5.8 oz, and measures only 5.04" long by 1.07" diameter, making it ideal for bolt actions, pistols, and PCCs where space is tight.
-
ECO‑FLOW™ Baffle System — Machined from heat-treated 17‑4 stainless steel, it delivers optimized sound performance with minimal blowback.
-
CARBON‑GARD® Sealed Core — A patent-pending silicone O-ring system keeps the core clean; after 2,000 rounds, the suppressor is still easy to disassemble with just a coin.
-
Zero First‑Round Pop — Extensive testing ensures one-and-done suppression, no awkward first shot boom.
-
Quick‑Detach EZ‑LOK™ QD Mount — Ships with a 1/2×28 adapter; also compatible with direct-thread or CAM‑LOK rear mounts for user preference.
