ok so i bought a few milled yuckoslavian milled parts kits off of centerfire last week and they should be here on monday. I also ordered a few receivers w rails off of ar15plus.com for 40 bucks and they dont even have em manufactured yet so im not sure if ill have em be next weekend when i planned on taking some time to do the build. My questions are:

1.) are there any other companys that sell quality laser cut ak-47 receivers and have them in stock?
2.) are there any forseeable build issues associated with welding a milled trunion to a stamped parts kit. I plan on grinding material off of the trunion so it will fit and ive seen a friend who did this same thing and it turned out great. im just wondering if welding the receiver to the front trunion will create any issues with the heat treating on the trunion.
3.) has anyone ever done a weld job instead of rivits, u drive screws, screws, toothpicks, jb weld, ect.?

also how long do yall figure cheap parts kits will stay available since this ew assault weapons import barrel ban crap went into effect, if this first build goes well i might want to but a few more parts kits to throw in the closet as an investment, they might actually be worth something one day

I have done it , by fabricating the missing receiver pieces out of 4130 aircraft plate & welding in the trunnion & rear receiver sections and grafting in trigger guard piece - alot of work - i can post pics if U would like

Does a milled kit even have a Trunion? I have a milled arsenal and there is no Trunion the barrel is pressed into the receiver or so it appears.

You're correct, a milled AK doesn't use a trunnion. The general idea is to use the front receiver stub from a torch cut milled Ak kit as the trunnion for a stamped build. Square it off, mill it down to fit inside a stamped receiver shell & drill/tap for button head screws/weld in place.

Buzgun, I had the same idea but havent quite started yet. Did you MIG weld your receiver or did you TIG it? I would love to see those pictures by the way.

Ok , i started with a Russian type 2 1954 kit , it came with a russian type 3 back receiver section , so i had to do some modifications - witch made it more challengeing , i chose to TIG weld this - so i could controll the weld penetration , and eliminate ugly cosmetic weld porosity , - first i fabricated right & left sideplates out of 4130 aircraft plate - 5/32' thick - i welded in upper & lower rails out of same material , i then welded left sideplate to cut receiver trunnion stub , i welded from inside the mag. well first , then hit the outside of receiver, then-, checked for straightness , then welded on the right side plate - then i grafted in the "modifiedtype 2 " back receiver section , then i grafted in the trigger guard cut receiver section , i welded the sideplates to trunnion with er70s6 welding rod - ( so not to overharden) and for rails i used 4130 welding rod -TUFF SHT! , i had to grind out the insides of sideplates down to approx. 80 thous thick in F.C.G. aea- so i could get the E clips to go on over H.&T. pins--- the only reason i did this , is cus the Russian type 2's have some collectability factor - this was a lot of ballbusting work! , i wouldnot recomend it , cept if the piece has some collectors value ! , I work for my uncle , who has a Sht load of welding equipment-( MIG, TIG) and a full machine shop , so i had that in my favor , but it took 11 solid hours of work to do this , if U have specific tec. questions , i will provide answ. , good luck !!
