Whether you are building from scratch or retrofitting an existing AK to accept any of the 1913 rail compatible stocks or braces on the market, the new 1913 Rear Trunnion is now available.

Our Picatinny 1913 rear trunnion is milled from a solid block of 4140 Chromoly steel on our in house CNC. It has a mil-spec 1913 rail which will take any of the various SIG style stocks and braces. The 1913 rail has a 2 degree down cant for ergonomics. The hole pattern is standard AKM, which usually will allow for easy retrofitting by a kalash-smith on existing guns. They take the standard 4.5mm Long rivets. We’ve made a bunch of weight relieving cuts without sacrificing strength; the weight of the trunnion is 197 grams or 6.94 ounces. Made 100% in the USA. Not guaranteed to work for Yugo or Norinco guns.
