SB Tactical SBM4 Stabilizing Brace
NOTE: Works best with the STDT Buffer Tube (sold seperately) with this Brace. Industry Standard 6 position tubes are not compatible. The cavity on the brace is ideally suited for buffer tubes from 1.10" to 1.25".
The SBM4 Pistol Stabilizing Brace® is the evolution of the original SB15™. Thinner, lighter and with enhanced cheek weld ergonomics. The SBM4 provides increased stability, improved accuracy and usability.
