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.
J-MAC just released their own modular rear trunnion a few months that looks to be a quite a bit lighter than this Occam Part. At 7 ounces this is still heavier than a standard AKM trunnion with a Defintive arms stock adapter.
I like the direction Occam Defense is going but they need some more lightening cuts on their billet steel products.
I wish they included a pic of what it looks like on an actual rifle….
Agreed. The closest I have seen to that are some mockups with prototypes on their Instagram.
I hope they offer a version with zero cant. If you have a higher optic, you don’t need it, and it helps keep recoil inline with the bore.
That might be good feedback to pass directly to them via email. Their original prototypes had zero cant.
