Griffin Armament Dual-Lok PSR Features The Griffin Armament Dual-Lok PSR draws on more than ten years of over the barrel suppressor development that began with the RSTA and SPR models. Those earlier designs were built to diminish blow back provide superlative accuracy and excellent point of impact shift characteristics while adding minimal length to the host rifle and the Dual-Lok PSR carries that philosophy into a next generation reflex suppressor. Its Stainless Steel and Inconel construction is chosen specifically to withstand the heat and pressure of over the barrel operation where the suppressor bore surrounds a portion of the barrel itself. Rated for full auto use it is built to hold up under sustained high round count strings of fire in demanding environments. Finished in Flat Dark Earth Cerakote the Dual-Lok PSR measures 8.9 inches long with a 1.5 inch diameter and threads onto a 5/8x24 pattern keeping installation straightforward on a wide range of .30 Caliber rifles. At 15.8 ounces it adds relatively little weight to the muzzle end which helps preserve the rifle s natural balance and point of aim shift compared to bulkier over the barrel designs. The Cerakote finish also adds a layer of corrosion resistance on top of the Stainless Steel and Inconel build suiting it to harsh field and duty conditions. For shooters chasing the specific sound and handling signature of a reflex suppressor the Dual-Lok PSR is available for sale at GrabAGun as a durable field-ready solution.
