Griffin Armament HRT-556 5.56 1/2x28 DUAL-LOK

Overview

Griffin Armament HRT-556 Features The Griffin Armament HRT-556 is constructed from stainless steel and Inconel with a black Cerakote finish delivering a full-auto rated 16.50 oz suppressor at 6.30 inches and 1.50-inch diameter purpose-built for 5.56mm host platforms. The G2 ECO-FLOW baffle stack reduces gas backpressure and improves cyclic performance of the host firearm compared to the G1 configuration with a thicker blast baffle providing vastly increased durability over the already robust first-generation design. The low-profile flash hider endcap works in conjunction with the ECO-FLOW baffle stack to minimize flash signature at the muzzle across tactical applications. The DUAL-LOK mounting system provides an accurate robust and wear-free suppressor interface with broad muzzle device support across 1/2x28 threaded 5.56mm host platforms. Designed from the outset for minimal POI shift and gas blowback the HRT-556 G2 delivers high sound signature reduction while maintaining the host firearm s cyclic reliability under sustained fire. The Inconel component selection provides the high-temperature material properties required to withstand the thermal demands of full-auto rated suppressor use. Griffin Armament originally developed the HRT-556 for elite HRT unit use designing the suppressor around the specific operational requirements of close-quarters tactical teams that demand maximum durability minimal flash and reliable cycling in compact suppressor packages. The G2 iteration incorporates improvements across the baffle stack blast baffle and endcap geometry to advance those original performance objectives. The HRT-556 stands as the shortest suppressor in the Griffin Armament DUAL-LOK lineup prioritizing compactness without sacrificing full-auto rated durability.
