This version of the RSA stock adapter will be 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 RSA line, will allow you to install 1913 stocks/braces

Cheek wield is adjustable by moving the stock/brace up or down on the rail.

This is a great adapter and works great on the KP-9. I will be getting another one for my AK105 pistol build. Excellent fit and finish.

Love it!

Just bought this for my KP-9. Was easy to install, and now I have a sweet side-folding SB tactical brace on my 9mm AK pistol. Totally worth every penny! Keep making awesome products y'all!
