Brownells 75th Anniversary - A Shooting Heritage

Stability & Improved AR Pistol Control

The SBX-K Pistol Stabilizing Brace is SB Tactical’s second generation brace designed for Sig Sauer’s MPX and MCX line of AR-15 style pistols. Made from a high-quality, elasto-polymer, the SB Tactical’s SBX-K Pistol Stabilizing Brace can be strapped around the shooters forearm for better accuracy when shooting one handed.

With a more streamlined design than its predecessor, the SBX-K Pistol Stabilizing Brace employs a wider strap to give extra stability when strapped to the forearm. Brace can also be pressed against the cheek for a third point of contact to stabilize the pistol when firing.

  • Fits 1" to 1.2" dia. buffer tubes
  • Adjustable nylon stabilizing strap
  • Can also be used on conventional AR-15’s

SB Tactical products are designed and intended only for use as forearm braces to provide a more stable firearm platform. They are neither designed nor intended to be fired from the shoulder. As configuration changes may alter the classification of a particular firearm, the user bears sole responsibility for determining the correct application of state and federal law.
