YHMs line of sRx products were designed with aesthetics and ease-of-use as the top priorities, and that is no different for YHM sRx Muzzle Devices. 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. Adds minimal length and weight to the suppressor set up, while also allowing you to reap all the benefits of the new 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-that’s 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.
