Product Description The Yankee Hill sRx Q.D. Muzzle Brake (Short) is a low-profile, steel muzzle device finished in black phosphate and built for the YHM sRx (Suppressor Rx) system. Designed with aesthetics and ease of use in mind, it interfaces with the industry-standard HUB 1-3/8 x 24 mounting thread pattern and uses an internal taper seal in front of the threads to help lock the suppressor setup securely while reducing gas and debris buildup on the threads during use. This muzzle brake must be paired with the YHM sRx Adapter (YHM-4400) to complete the sRx quick-detach mounting system.
