I stopped visiting Akfiles because the know-it-alls there drive me to drink, you've got 21 year old kids with 12,000 worthless posts telling me ( a veteran AK builder for almost as long as they've been alive ) that receivers have the be fully heat treated, blah, blah, blah....I have a full auto AK with easily 10 K rounds thru it, no heat treat on anything but the ejector , its even on an old Tapco flat where you had to pound the top rail over on the 555th jig when bending it ( circa 1999-2000, pre AKbilder stuff was even a thought ) ......they get butt hurt when I show them pics and tell them eat a bag of dicks. Most of them don't know anything more than they read on the internet, but hey if its on the net, it must be true....bonjour
I fondly remember an AGI AK47 Gunsmithing video (on VHS) showing the proper way to build a kit was to just hammer the rivets back into the holes you drilled them out from without pulling the barrel.
My first build was with screws, 10/32's on a bent tapco flat as well. Redneck heat treat. Gun ran fine, I didn't put 10K through it but at least a few thousand and never had any issues with it. The whole "heat treat" thing I think was from those B-WEST's but I personally think that was more of a piss-poor choice for steel in the receiver and not so much with the heat treat, but I dont know. From a manufacturing stand point one would think a whole-receiver heat treat is the cheapest/most effective way to go, IE in batches.
Alot has changed for home builders over the last decade or two. All I can say is I wish I had bought pallets of kits back then. I still have some of the $79 romanians, rebuilt most of them for aesthetics purposes though.
I have an IO trunnion here I'd gladly donate to your cause
