pengyou 0 Posted November 3, 2019 Report Share Posted November 3, 2019 I know this topic was brought up a year and a half ago...does anyone make an 80% "lower receiver" for the Saiga 12? I know it is not called a receiver...but something similar. Quote Link to post Share on other sites

ewoketeer 35 Posted November 5, 2019 Report Share Posted November 5, 2019 Best case for that sort of thing would be a flat plate cut to shape with various holes cut/drilled, which you would then fold for your base receiver, then add trunnions, rails, and other items to finish your receiver. I remember seeing those plates at various gun shows back in the day... Quote Link to post Share on other sites
patriot 7,197 Posted November 5, 2019 Report Share Posted November 5, 2019 Easy enough to bend one up yourself with basic hand tools. You can get the sheet metal @ McMacter-Carr Quote Link to post Share on other sites
G O B 3,516 Posted November 6, 2019 Report Share Posted November 6, 2019 The front trunnion is the serial numbered part. This negates any value in replacing the sheet metal housing normally called the 'receiver' on AK's. 1 Quote Link to post Share on other sites

ewoketeer 35 Posted November 21, 2019 Report Share Posted November 21, 2019 If you have the machinist's drawings for the trunnions, you could, theoretically, make your own,,, Quote Link to post Share on other sites

gunfun 3,931 Posted December 2, 2019 Report Share Posted December 2, 2019 And the right grade of steel, and the ability to precisely heat treat. ARs are easy to make because all the pressure bearing components are non serialized in USA. Those are the hard bits to make safely at home. Europe doesn't care about receivers for that reason, they care about barrels, bolts, trunions, etc. Hence serials on those parts in EU guns. Import AKs tend to have serials on both parts as a compromise to the US system. The S12 and derrivatives got approved using the system from Europe, without any thought towards making them easy to clone or remake. There's no money in that for the manufacturer, and no surplus market, since it was never a mass issued gun to turn into parts kits. Further, all the pockets in an 80% Ar receiver are vertical plunge operations. Everything tricky has already been done. An AK trunion has a lot of complex geometry that isn't just going to happen with a drill press. It would be pretty hard to measure without custom jigs, let alone make. Part of why ARs are clever, is that he borrowed johnson's clever thinking about how to make easier to machine precise lugs, then made it in two pieces, so that it is a single broaching operation which can be cleaned up on a lathe, then joined to the barrel, then heat treated as a unit. 2 Quote Link to post Share on other sites
