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 our T/C grip with 1913 interface, 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
• 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.
