Perfect Fit by Brian, February 13, 2024
This fit perfectly on my PSA AK. I only had to slightly file the hinge to fit. It locks into the extended position with ease and is very sturdy. It also folds easily and stays in the folded position. I couldn't be happier with it.

This M4 tube adapter replaces the standard buffer tube to ensure the stock folds as flat as possible!image

This version of the SM stock/brace adapter is specifically made for 4.5mm pin folding stocks. 4.5mm trunnions can be found in the SLR 104/106/107 UR/CR/FR. This stock adapter, like the rest of the SM line, will allow you to install all of their Arm Bar and Stocks as well as SIG style stocks. Cheek wield is adjustable by moving the stock/brace up or down on the adapter.
