The TBAC SR NTB Non-Timed Muzzle Brake in 3/4×24 is the Thunder Beast Arms Corporation SR Non-Timed Brake, a version of the SR brake that does not require timing. It is made for shooters who will almost always shoot suppressed, since the brake performance with no suppressor is reduced against the normal SR brake because of its smaller ports. It has ports on three of its six sides. Thunder Beast finishes it in Ionbond DLC in a monocolor dark gray. This 3/4×24 version fits barrels threaded 3/4-24.
