SB Tactical set out to improve the handling of AR-type pistols with its SB15 arm brace. The SBM4 is an enhanced and streamlined design that, like its predecessor, facilitates a safe and functional shooting position when installed on an AR-pistol’s buffer tube. Made from polymer, the unit mitigates the fulcrum effect that a single point of contact can cause by embracing the shooter’s forearm. Adjustable nylon straps help retain the pistol in a safe shooting position. Price: $149. Contact: SB Tactical LLC; sb-tactical.com.
