SB Tactical SBM4 AR-15 Pistol Brace - Black


The SBM4 Pistol Stabilizing Brace is the evolution of the original SB15. Thinner, lighter and with enhanced cheek ergonomics. The SBM4 provides increased stability, improved accuracy and usability.  Stabilizing braces are designed to assist in one-handed shooting or for shooter's with disabilities. 

An SB brace can be mounted to an AR-pistol and still be classified as a pistol (compatible with Concealed Weapon Permits that mandate pistols for concealed carry.)   Whereas the attachment of a stock to an AR-pistol would change the classification to a Short Barreled Rifle (SBR) which would require a $200 tax stamp and is not legal in all states.
