SOLD: New, Unused Side-folding Sig Brace (MPX/MCX, 1913)

AndyG · May 2, 2020

Sig Brace w/ side-folding 1913 knuckle came with an MCX pistol recently purchased new-in-box. I already have a brace and have no need for a second. Asking $100. Can be reached by PM or by text at 337-344-forty-one-06. In Lafayette.

How does it mount? I’ve got a Sig upper and lower I was going to put together but I can’t figure out how your stock mounts.

the brace has a folding knuckle adapter to accommodate installation on the picatinny backside of MCX, MPX, etc:

not sure if the adapter can be removed and the SIG brace used like a buffer tube. will look into to it and get back to you.

update: Believe the brace is designed to slide on/off a buffer tube with alot of effort and a little lube. Looks like the adapter should unscrew from the provided tube, but Sig has it torqued down so dang tight, I can't tell for certain. Would rather leave intact than risk scuffing it up on an attempt to disassemble.
