SM adapters utilize the factory rear trunnions and eliminate the need for additional adapters or folding mechs for use with JMac's 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.
The SM-5.5 is specifically made for the Russian 5.5mm pin folding stocks. 5.5mm trunnions can be found in the SGL (Saiga) rifles and on the new KUSA vityaz clone.
