Questions & Answers
Will this work on an AR 15 pistol? I currently have the Sig Brace and I would like an upgrade option. Any other options one would suggest? Thanks JB Expert Answer

No, this is designed to work for Sig MCX/MPX only as they do not require a buffer. This braces fits to the specific 1913 rail at the end of the receiver, there is not a way to attach it to a pistol buffer tube.

Helpful Positive Review SB Tactical Collapsable Brace by Buffalo Soldier, March 5, 2018
The brace fits snuggly and functions as expected. Note with the redesign, the button you depress to enable moving the brace is on top now. This button will somewhat impede the charging handle. Which may require more diligence when pulling the char...
