Sig sauer folding stock/brace - SIG SAUER MCX/MPX Telescoping And Folding Stock Black - All NFA Rules Apply STKXFOLDTELEBLK

Great experience, from the ordering and delivery process with Optics Planet to the Sig Sauer stock/brace. It is a high-quality product and fits the picatinny style adapter on the Ruger 22 Charger. It took a few minutes to learn how to open and fold (no instructions). Important to note there a heavy spring that requires a lifting motion to fold. For the first few times you may have to pry up the mechanism. I used a flat head screwdriver wrapped with electrical tape. The spring seems to loosen the more it is used. The arm and bracket are high quality made from aluminum. The fit is pretty good. The top of the brace is a little lower than the adapter, not flush. the underside allows plenty of room for the hand. There may be other brands to choose from, but this works perfectly for me.
