I purchased an AMD-65 kit-build and immediately noticed some problems. It was built on an ITM MK-99 (OOW). The receiver had to have been 'pinched' at the fcg area, because the receiver is bulged downward at the trigger (causing the rear of any mag to sit too low). I thought I could 'bubba-fix' the problem...until I fired a test mag...and the rivets on the left side started to shift - and one egged! So, getting the opinion af a local home-builder, the receiver is both out of spec AND garbage. I ordered a NDS-65 and need to find someone to replace the receiver. I do not have the equipment, and the builder who inspected it said it was well worth replacing. Any takers? The receiver should be splashing down at my door within the next week along with 2 sets of rivets from AK-Builder. Any ideas?
