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).

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