The Yankee Hill Machine sRx Mini QD Muzzle Brake in 5/8×24 (Yankee Hill Machine part no. YHM-4401-MB-24) is the 5/8×24 version of YHM’s shortest sRx quick-detach muzzle device. It is meant for hosts with a 5/8×24 muzzle thread and it mounts a suppressor through the sRx taper interface. The body is only 1.1 inches long, so it adds little length or weight. Yankee Hill built the sRx line around a low profile and easy use, and each piece is made in the USA.
