Griffin Armament DUAL-LOK PSR Series
The Griffin Armament PSR (Precision Shooting Rifle) series represents the accuracy-focused tier of the DUAL-LOK® suppressor family. The PSR 5 covers 5.56mm and the PSR 7 covers 7.62mm. Where the HRT emphasizes extreme durability for hard use, the PSR prioritizes maximum internal volume, accuracy, and signature reduction — making it the ideal choice for precision rifle shooters and competitive shooters. Both use the patent-pending DUAL-LOK® active retention QD mounting system. Compatible with all DUAL-LOK® muzzle devices. Manufactured in Watertown, WI.
