Works " great " - DoubleStar Push Button Folding Stock Mechanism w/o Boss

This adapter works as intended when used with a brace or stock. It locks in both positions open and folded. Although, there is slight movement in the folded position. Lock up in the open position is firm. I'm hoping it stays the same after repeated use. Will purchase another one to keep as a spare. Would have even 5 stars if it wasn't for for slight movement in folded lock up position.
