Anyone tried this? I've managed to acquire these parts: Chinese neutered long collar underfolder FSB unit, SKS front sight unit with bayonet "lugs" to be chopped and weld onto the AK unit, I have enough scrap steel to fab the front lugs from, original Poly bayo and underfolder lower HG. I "could" possibly weld on the rear lugs, but at what I paid for the parts, I'm not really eager to go putting my welding skills to the test. I do know the SKS lugs use a screw instead of the AK pin, and those holes will have to be drilled out a bit larger to the right size. I'm mainly interested in pics, posts, or other information from anyone that has taken on a project like this. Thanks.
