Description
Griffin Armament DUAL-LOK PSR 5 5.56 Suppressor Features The Griffin Armament DUAL-LOK PSR 5 5.56 Suppressor is constructed from high-strength high-temperature corrosion-resistant 17-4 stainless steel with 718 Inconel reinforcement for demanding firing schedules. A tubeless laser welded design supports durability and consistent handling while the Cerakote finish provides added resistance to heat and wear. The patent-pending ECO-FLOW baffle system is designed to reduce blowback and a patent-pending Pressure Reduction Cap with an integrated flash hider further optimizes gas behavior and signature control. The patent-pending PSR DUAL-LOK wear-free mounting system requires no consumable parts and combines a taper lock interface with an ACME thread for quick attachment. A locking ring with three anti-rotation teeth prevents loosening and 120 effective positions provide a rock-solid mount with extremely low point of impact shift. The suppressor mounts on PSR DUAL-LOK systems and includes a PSR DUAL-LOK 2 Port Muzzle Brake in 1/2x28 for 5.56mm along with A 3/4 wrench flats on muzzle devices for easy installation and handling.
