I have 10 steel double stack single feed MAC magazines from Recon Ordnance. I welded a stop to the front to prevent over insertion and welded over the slot for the mag catch and re-cut it, then parkerized the magazines. They fit my gun wonderfully and look great but they will not feed.
They work when only a few rounds are loaded but if you put more than 10-15 rounds in a magazine it becomes so hard to load I have dented cases with my mag loader. When the rounds are removed they get stuck and there is a gap under the feed lips. All of the rounds above where they stick can be rattled out. The other odd thing is that as the rounds move through the magazine body they spin. It does not matter if the rounds are being pushed up or are going into the magazine as I manually lower the follower.
The inside width of the mag bodies is .730 (Same as Uzi mags which work) from the bottom to where it tapers for the single feed. I have polished the inside as best I can and tried them dry and with lube.
Here is a video of the bullets spinning as I push them up through the magazine:

And also a picture of bullets that are stuck in place. This was a loaded magazine that stopped feeding. All the loose bullets on top of the jam were shaken out.
Any help would be appreciated.
