Yankee Hill sRx Short QD Flash Hider | 5/8-32 | 444532

The Yankee Hill Machine sRx Short Q.D. Flash Hider (MPN 444532) is a compact quick-detach muzzle device intended for use with the YHM sRx suppressor system. It uses a tapered seal ahead of the threads to reduce gas and debris on the threaded interface and is built to add minimal length and weight to a suppressor-equipped setup. The device is best suited for low-profile suppressor builds and range or precision shooting configurations where a slim Q.D. mounting solution is desired. This flash hider is designed specifically to be paired with the YHM sRx Adapter (YHM-4400) and the industry-standard HUB interface.
