SM-4.5 adapters utilize the factory rear trunnions and eliminate the need for additional adapters or folding mechs. 

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 our 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.

*May require fitting on Palmetto State Armory 4.5mm trunnions.

*Does not lock in the folded position. (See RSA-4.5 + FM-SM-1913 Folding Mech if you require your stock/brace to lock when folded)

Attaching a stock to a pistol makes it an SBR and requires NFA approval. You are responsible for knowing and following your local/state/federal laws!
