    For someone who doesn't want to cut and weld a .064 receiver blank, here's a 4-piece weld-up Galil receiver for $35:

    Sideplates

    Looks like you'll have to weld in a front trunnion from something, though.

    [edit] I emailed them about the trunnion. I didn't think to ask about the top rails - I can't tell from the picture if the rails are bent over or if the tops are just notched.

    I have one of early Stenparts Galil weld kits and it used the front and rear section of demilled Galil receivers for trunnions. The rails, both upper and lower need to be welded in. You can get an idea of how he did his receiver if you check out the Galil pics on his project page.

    Did you ever finish it? How did it turn out?

    Not yet, still working on other projects and my welding skills are not up to it yet as I only have one set of de-milled receiver pieces and I don't want to screw 'em up.

    I was planning on a 6.5, but Green Mountain's 20" .310 blank for $30 was too good a deal to pass up.

    Looks like I'll have to scope out some nice Boxer-primed x39 brass.

    A friend is getting into bullet swaging, and he's been bending my ear about how easy it is to "bump up" small bullets to larger ones. The swaging guys claim it's much easier than trying to swage larger bullets down. Once I see what the bore diameter of the GM barrel is, I'll check on the price of a bump die for mashing .308 bullets up to .310-.311.

    There used to be a guy in Canada that sold Galil receiver sections. He had ones that were "US legal" and some that were more complete sections of receiver that he said weren't legal to send to the US. With the welded sections the lower rails could be made with stamped rails as long as they weren't too fat to clear the hammer. Welding the upper rails is reported to be a super pain even though they are easier to reach, they have to be welded the length of the receiver. I think a wide section welded across and cut after welding might be easiest.

    My receivers from Coldsteel showed up today. They're dimpled for the various holes, but I'll need to order some metric reamers to finish them.

    I'd wondered about using flush rivets. The Hadars all used milled Galil receivers. Just a moment ago I found some pictures of a Super Vepr receiver which definitely uses flush rivets.

    Anyone know of a good source for flush rivets?

    EDIT: Click "solid", then "coundersunk". It didn't seem to change the url going through the options...

    They only have stainless steel ones in that size, but you can always paint them if you end up parking or bluing the rifle.

    Hmm. Stainless steels aren't very malleable; I wouldn't have thought about using stainless to make a rivet from. I wonder what alloy they're using... hey! Click on "steel" under the "stainless" part, and it brings you to ordinary steel countersunk rivets.

    I wonder what *those* are made from... come to think of it, I've never seen any specs on what alloys rivets are made from. I need to haul my Machinery's Handbook back to the Throne Room for a while.

    They only have 3/16" and 1/4". 3/16" ought to work. The page shows the head diameter is .351", which is larger than the Vepr, and .079" high, or deep. I'd have to trim the head a bit, but it'd be easier than making rivets on the lathe. At $7.17 per pound, I'm willing to do a little extra work.

    Oh, I was thinking 3/16" would be too big [I've never built a stamped build before so I dunno]. Well, if you use the rivets as they are, then sand them flush it could look like the type 1 AKs with their flush rivets.
