Looking for M 79 40mm Grenade launcher receiver drawings that may be publicly available to fix defective "carbon fiber" M 79s made for us a while back before the manufacturer bailed

We have been able to finds production drawings for the 1911 (JM Browning Pattern) but not the M-79 to date

We would also be interested in the 1911 slide drawings, Colt Pattern if available?

The best way to contact is still our contact page
