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.

GRIFFIN HRT - G2
The Griffin Dual-Lok HRT-556 G2 is a light, quiet, durable 5.56 silencer. It has low backpressure, allowing it to excel on AR-15s without additional tuning. Ideal for situations where rack weapons can not be altered, the Dual-Lok HRT was designed with the expanding needs of today's professionals in mind. The secondary locking system provides over-the-top security, eliminating the chance of the silencer becoming loose. Unlike competitors, the Dual-Lok system is wear-free and can withstand the test of time, even under the most adverse conditions. The patent pending front cap further reduces external flash and enhances sound performance.
The tubeless design allows for less weight and more volume, translating into a quieter silencer than many others in the class. The baffles are laser-welded, preventing human error during the manufacturing process.
The Dual-Lok system is integrated into the silencer body to provide maximum accuracy and enhance durability. A precision taper interface between the muzzle device and mount keeps POI shift consistent and repeatable. An ACME thread allows for quick installation and attachment without errors. Positive spring tension uses a redundant locking collar for secondary retention. The anti-rotation teeth ensure the silencer doesn't back off under extreme circumstances.
