1913 rear trunnion
The best way to get a picatinny rail on your rear trunnion, this is exactly what I’ve been looking for for months, and machining and finish are top notch. Absolutely would buy again, 5+ stars.
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. There is a minor variation with MORRISSEY Receivers. They're about 1mm deeper, which leaves a line of exposed sheet metal across the bottom of the receiver. We've extended the "MORRISSEY" version of the part by a corresponding millimeter to cover up this cosmetic (non-functional) issue. If you're building off a Childers receiver or modifying an existing AKM you'll want to use the standard version (AKM / CHILDERS).

1913 REAR TRUNNION
Love the design and the build quality looks excellent. The rivet holes line up perfectly for my 80% receiver build.
