Just finished removing the front rivets on my Bulgie 74 (two beer job). Starting on my AMD63 front trunnion. Very easy with my Chicom drill press. I am on this forum more than any other, and damn near all my info has been from you guys.....much appreciated. OK now the stumper. A while back I read a thread either here or at one of the other two forums I'm on. This fella made his own screws or adapted them so that they were not flat on the receiver side of the screw. Instead they were shaped to draw into the receiver like a rivet.....very nice. He said he sold them too. Every search has turned up zilch. ANYONE remember anything like this? I would really like to get some of those screws. Thanks. KPD
