The YHM sRx Short Flash Hider (brand part no. YHM-4445-M14X1LH) is a quick-detach flash hider threaded M14x1 left-hand, built as part of Yankee Hill Machine’s sRx suppressor-mounting system. It mates with the separately sold YHM sRx Adapter (YHM-4400), which threads onto the industry-standard 1-3/8×24 HUB interface, giving a shooter a sleek, low-profile way to run a QD suppressor setup. An internal taper seal in front of the threads locks the suppressor in place and forms a tight seal, keeping gas and debris from building up on the threads while adding minimal length and weight to the overall setup.
