YHMs line of sRx products were designed with aesthetics and ease-of-use as the top priorities, and that is no different for the YHM sRx Mini Muzzle Brake (YHM-4401-MB). This Q.D Muzzle Brake’s compatible Q.D. Adapter/Mounting Interface attaches to the industry standard (HUB) 1-3/8 x 24 threads. It features an internal taper seal-in front of the threads-that locks your suppressor on and forms a tight seal to contain gasses while in-use. This means no gasses or debris can build up on the threads. The sRx Mini Muzzle Brake must be paired with The YHM sRx Adapter (YHM-4400). The sRx Mini Muzzle Brake adds minimal length and weight to the suppressor set up, while also allowing you to reap all the benefits of the YHM sRx System-when used in conjunction with The sRx Adapter. The full YHM sRx (Suppressor Rx) System will be the obvious choice for someone looking for a sleek, low-profile, suppressor set up-thats also built to withstand rigorous use. This is our prescription for the shooter who cares about the aesthetics of their build as well as its ease-of-use.
