Description
Griffin Armament Dual-Lok HRT-556
The Dual-Lok HRT-556 is Griffin Armament’s shortest and most durable 5.56 suppressor, originally designed for elite hostage rescue teams and now available to the commercial market. At 6.3″ and 16 ounces, it delivers low backpressure performance that allows AR-15s to run reliably without gas system modifications.
The Dual-Lok mounting system uses a precision taper interface and ACME thread for quick, repeatable attachment with consistent POI shift. The secondary locking collar provides 120 effective locking positions with anti-rotation teeth to prevent loosening. Unlike ratcheting QD systems, the Dual-Lok design has no wear-prone parts.
Note: This suppressor is NOT compatible with the Dual-Lok Stealth Flash Suppressor (2.75″) or the Dual-Lok Bayonet Flash Hider.
Available in Black and Flat Dark Earth
