Rugged Rx modular blast diverter and brake. Just like our modular rifle and pistol suppressor’s, this revolutionary design allows the end-user to choose between a blast diverter or muzzle brake by simply unthreading the brake module and changing muzzle caps (included). The Rugged Rx features 100% billet 17-4 stainless steel construction along with our Dual Taper Locking System. Making it fully compatible with our rifle line of muzzle devices. The Rx is finished in an ultra-hard black nitride finish to provide years of service.
