Sig MPX Brace
More questions?
This is a newly designed folding Brace assembly for the MPX Pistol. We used one of the famous Fab Defense Polymer stock hinges as the starting point and custom adapted it to the cool MPX with our own CNC cut 6061 aluminum adapter. These are very solid platforms and lock up extremely tight when opened. This SIG Arm Brace model does have some spring tension against the frame when closed so it won't easily flop open. These mount by simply sliding the stock onto the rail and securing with the Nylon tipped set screws. Takes less than 3 minutes to take on and off. This auction includes the COMPLETE Folder mount, tube and SIG SBX15 Gen 2 Arm Brace and mounting hardware as pictured.

We are currently shipping MPX stocks within two days of ordering.
