Description
Griffin Armament Dual Lok 5.56 Suppressor Features The Griffin Armament Dual Lok 5.56 Suppressor is built from high-strength high-temperature corrosion-resistant 17-4PH stainless steel with 718 Inconel reinforcement delivering durability and long-term performance for hard-use tactical applications. A laser welded tubeless design supports a strong strength to weight ratio while the High Temp Cerakote finish adds protection against heat and wear. The flash reducing flow optimized end cap further enhances overall performance by helping control signature and gas behavior. The DUAL-LOK system uses a taper lock interface for secure accurate mounting combined with an ACME thread for fast attachment and a locking ring with three anti-rotation teeth to prevent loosening. With 120 effective positions it provides a rock-solid mount with extremely low point of impact shift and the wear-free design eliminates the need for consumable parts. The suppressor is compatible with DUAL-LOK mounts and includes a DUAL-LOK Minimalist Brake in 1/2x28 along with A 3/4 wrench flats on muzzle devices and a nitrided black collar for increased hardness and resistance.
