    Please do, if someone makes an 80% or partial receiver that's not too crazy on the price, I think I'd get one.

    Some people will assemble it to set the distances with the top cover and other parts, there's some that use a jig.
    Yes it's best to use a copper backer, less clean up on the inside.
    If your kit has large gaps, it would be best to use a filler/repair plate to fill them in.

    repair plates? no... im using a aluminum block with holes drilled and tapped with the rivet holes to create the proper distance for the different slices... Thompson machines.net 2010 are printed on the pictures i have for the exact distances, tho.... there's differences between the PKM and PKT receivers... rivet holes and such... also, no clue what a "battle pack" holds on to for a PKT... because im sure that was part of the mount? doesn't it go under the gas tube thinger? also, FOR INFORMATIONAL PURPOSES.. i bought a PKM gas tube + bipod on gunbroker awhile ago... and a RPK bipod could easily fit onto the original gas tube with some lathe work... yeah, work, but cheaper in the long run, literally the same bipod system... bought one from apex for a mg-74-47 build... figured i spent the money to tell you guys whats up... also, very interested in a 80%... this reweld shit is way too much work... tho once i get this jig down, i should be able to smooth out the process for possible further builds if i choose to do so

    OF COURSE you can retrofit one with using parts for the distances! The issue is going to be configuring the scrap pieces with the appropriate "semi-only" conversions BEFORE welding up the pieces. That is the huge issue. Weld in your restrictor plate; grind off the sear catch on the bolt carrier, and weld away!

    Problem is, that for me, it seems like it would be more hassle to reweld scraps than it would to build from scratch. I am working with a $50 shell from Pirate - projectguns.com - and am facing the issue of making the dimple on the bottom for the feed arm clearance. I kind of got it, but it could be cleaned up and done better. I might buy another $50 shell just to have it on-hand.

    Make that bottom dimple and the rest is fit-and-measure for the parts. Start with the trunion and work backward. Spot weld the rails like a normal AK. Grind some steel to make the charging handle plate and spot weld it on. To me, that process is easier than rewelding on scrap pieces. The issue with rewelding scrap is that the heat damage the pieces have suffered have PROBABLY warped them enough that it will never flatten out again.

    Either way will get you there. Just may not look as pretty.

    Now about blueprints.... Blueprints suffer the issue of possibly not being accurate, and really if you already have the parts in your hands, then why would you need to measure from a blueprint when you can just as easily get measurements from the acutal part?

    Oh and don't count on a company releasing blueprints that would allow you to avoid buying their product!

    Putting in a Semi shelf in the bottom (The 0.25" one) Makes a great foundation for easier spacing of the cut pieces and holding the dimensions correctly to Re-weld.

    Well Im one step closer to finishing my receiver. (75%-er) I need to verify some dimensions before I cut it up more. Slow going right now.

    Originally Vitor claimed they wouldn't sell 80% receivers because the ATF didn't like licensed firearm makers to sell 80% receivers. ( The ATF considers any forming material of a receiver for the purpose of making a firearm qualifies the piece as a firearm. In theory a firearm maker can't have both unfinished firearms and 80% non-firearms. Then Prexis offered 80% PKM receivers and I think at one somebody claimed they were made at the same place as or at Vitor. The last I time I contacted Prexis they had a long wait time. Something like 3 to 4 months. 8 to 12 weeks I think. It might have even been 6 months. Maybe I should have ordered a couple of them.
