I picked up a home-built Romanian G yesterday at the gunshow that had been assembled with screws on a flat.  Normally, I wouldn't have given it a second look, but it looked clean and the guy only wanted $200 for it.  I offered $175 and he took it.  I figured it's worth at least that much as a parts kit.  

This morning, I unscrewed the rifle and tossed the receiver since I tend to distrust that sort of work when I don't know anything about the person who built it.  Plus, I have several old AUSA receivers in my vault anyway.  Wasn't even close to 922r compliant, either..but that's a different story.  Luckily, I've got plenty of US parts on hand to fix that particular issue.   Everything appears to be in great shape.  The trunnions are threaded, of course, but it's cleanly done.  

When I get some time this fall, I plan to properly rebuild it with rivets.  Are there any issues I should watch out for when rebuilding a "screw-built" kit?  Should I use oversize rivets to accommodate the threaded trunnions?


Edited 10/20:  Finished it...

Not my best rivet job, but after 300 rounds last night and another 150 rounds this morning with no issues, I think it will be fine.  Now I just need to find a muzzle nut to replace the slant brake and I'll be happy.

It depends on what size screws they used when it was assembled last time.
If they used 10-32 you should be able to use regular rivets, as long as the holes were not made larger before taping.

I have rebuilt more than one screw build.

Like was already said; as long as the holes weren't drilled over-sized for the screws a normal rivet set will work fine.

Great.  Thanks for the info. The holes don't appear to be drilled oversize, but I'll mic them before I start, just to make sure.

all you have to do is take out a screw and insert i rivet and see how loose it is you really dont need a mic, If its too loose you can always get bigger rivets and trun then down on a mill or on a drill press and a stone to make them to the right width... then all you have to do is cut them to the right leanght,, Ive made many cross member rivets in a pinch////

Well, I decided to tackle the build while my twins were at guitar practice this afternoon.  Took about 30 minutes with a standard rivet set and it turned out great.  Only had time to run 300 rounds through it, but I didn't have any issues other than a slightly sticky mag release.  A few passes with a file should smooth that up a bit.  The finish looks like crap, but it's just going to be a beater/loaner, so I don't care what it looks like.  I'll get some pics of the ugly duckling up tomorrow if the sun comes out.
