A3 Tactical is proud to release our Modular Folding Arm Stock system for the popular SIG line of MPX/MCX firearms. This system is designed from the ground up to provide modularity in style, form, and function.  The proven Sig hinge (provided) utilizes a positive spring-lock for both the open and closed position, allowing the user to quickly release the brace from either position.

NOTE: This Modular folder uses the OE Sig hinge. Due to the small offset of the Sig hinge the buttstock rests against the side of the firearm when folded.
