I am thinking about milling the bulge off the yugo trunion. Is this a bad idea? It would leave about the same amount of material that is on a Romanian trunion. I am thinking about doing this or trimming the receiver to fit right below the bulge and then weld where the two meet. Thanks for all the great ideas.

If you machine off the bulge flush with the rest of the trunion, I think it will be skinnier than a regular AKM front trunion. The yugo receivers are made with 1.6mm thick sheet metal, so the trunions are about .6mm smaller in width.  Most other stamped AK's are made with 1mm thick sheet metal. Its possible to use .3mm shims on both sides of the trunions to get a tapco flat to work. Or just don't grind all of the bulge off. I hope this helps.

I know of a person that used a Tapco flat with his. He cut around the original receiver where the buldge is. Then cut the Tapco receiver to fit around it and welded it to the original receiver part on the buldge. TIG welded it at that.

If you don't want to go with that, try one of the Yugo blanks out there...

Just don't go milling a perfectly good trunnion.
