Brownells 75th Anniversary - A Shooting Heritage
Menu

SB Tactical's FS1913™ is a folding stock / stabilizing brace that clamps securely to any firearm platform that has a MIL-STD 1913 Picatinny stock attachment point at the rear of the receiver. The FS1913™ is ideal for use on the SIG MCX / MPX platforms, as well as the SIG Rattler and Rock River LAR-PDS - or any similar firearm with an M1913 stock interface. With it installed, you'll enjoy better control of the firearm and a more comfortable shooting experience during sustained fire.

The FS1913™ is a straightforward "strut" type brace that provides a shooting interface similar to that of the factory MCX / MPX stock. It folds to the left, so it will not interfere with the MCX / MPX ejection port when stowed.

  • Ultra-strong, smooth-operating STEEL hinge mechanism
  • Light-weight polymer strut
  • Stock folds to the LEFT
  • Fits SIG MCX / MPX / Rattler & Rock River Arms LAR-PDS
  • Also fits other firearms with a MIL-STD 1913 Picatinny stock attachment point
  • Nylon strap enables use as a pistol brace
  • Comes fully assembled, ready for installation
  • ATF compliant

The SB Tactical FS1913™ deploys in the blink of an eye and locks open with reassuring solidity. Locks closed, too, to prevent accidental deployment. It looks spindly, but when extended, the FS1913™ provides a pleasantly secure shooting platform for more accurate aimed fire under stress. An adjustable nylon strap threaded through the buttplate enables use as a stabilizing brace when installed on pistol versions of the above firearms.

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.
