SM-5.5 adapters utilize the factory rear trunnions and eliminate the need for additional adapters or folding mechs.
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, not to mention, the trunnion itself is more readily available than the 4.5mm version.
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.
