I thought I responded to this last night, but I have this to contribute.
1. check the cause of magwell fitment by cautious fitting into the latch, receiver rear area and center support with the mags. File to fit.
2. The feeding problem should be resolved after that(and a cleaning of your mags). And you can not say there are issues until youve loaded a round and fired it at typical pressures at the range. It takes this sometimes to break the rifle in. Every rifle ive received from a builder has been on the TIGHT side, but never failed to feed after a live round was shot...... This is a good thing.
3. The cleaning rod issue seems to simply be an issue of too much patch. Cut your patches in half and try again. And you get twice the patches!
Hope this solves the issue. FYI. Ive never had a malfunction with an AK. No joke.....
