The SB Tactical FS1913 is a pistol stabilizing brace built to mount on any platform with an M1913 interface at the rear of the receiver, and is specifically sized to fit the Sig Sauer MPX and MCX (brand part no. SBTC FS1913A-01-SB). SB Tactical builds it around an advanced steel hinge and a pull-through design for quick deployment, with an aluminum strut and adjustable nylon strap for a secure, repeatable fit. At a genuine 9.6 inches and 10.0 ounces, it stays compact without adding excess bulk to a braced pistol build. Made in the USA from polymer and aluminum, it’s a proven, purpose-built brace rather than a generic universal-fit accessory.
