I have been plugging away on the hack job I received from the Boy Wonder AK smith, bridal wear tycoon and chicken farmer Gucci-goo. The Gooch pressed my Bulgarian 74 barrel into a saiga 7.62 reciever that retained its 7.62 trunnion. I have head spaced the '74 bulgarian bolt and just switched off the old dremel after making the following modifications so '74 mags would work.
1. Ground out the back of the mag well.
2. Ground the forward part of the re-enforcing rivet.
3. Ground out the underside of the trunnion where it contacts the magazine lips.

Now the representive sample of '74 mags I have on hand snick right in the mag well. But they wobble a lot. Anybody have any suggestions on how to slightly reduce the forward part of the mag well to cut down on the wobble ?

Guccanio I still have a gas block I need you to press on a 47 with your asshole while I hold the weapon !  

Yes Campy side to side wobble. I have played around with putting some brass sheet stock between the lower edge of the rails and the bottom of the mag well cut out. That helps a little, but my biggest area of wobble is at the front of the magazine well right between the lower trunnion rivets. It seems to me that the 7.62 trunnion is wider in this area than a '74 trunnion.  

BTT - any suggestions ? I know I ain't the first to have this trouble.
