Good not best - SIG SAUER Pivoting Contour Folding Brace for MCX, MPX

Bought this brace for a 9mm PDW and has been mostly trouble free so far. Something to be aware of is that the brace end spins pretty freely and the clam shell likes to open up a little. The spring is also pretty strong when trying to fold, I can do it one handed, the gf has to use 2 hands, unfolding is pretty easy. When installing, make sure its aligned correctly with the rail section, learned that the fun way! Overall I would say this brace is the best for the application, could use some improvements though.
