I have mags for the 60s to 09. They all seem hit or miss. I think Im down to modifying the mags. Seems like machine work would be a pain in the ass and same paper may be a bit harsh.

well you can try a slight squash in a press. It's stamped steel.

try older 20 rounders in it I bet they all drop free (if memory serves) there was a variation change during the viet nam era guns that changed the magwell dimensions slightly (also a variation changing the outside dimensions which we all know)

General motors.

Yeah I figured that would be the one you would bring up.

General motors.

Chances of it being the magwell are slim. I think that the problem likely lies with shitty USGI mags.

Olympic and many other manufacturers have had problems with magwell sizing on their casting dies, many of them have put out recalls on them. It isn't that uncommon.

Right, that's one of the problem he's describing. Tight magwell isn't an easy fix. Check for burrs or casting flaws, but more than likely you're gonna live with it, or find a better fitting mag.

Wont solve the problem of the mag hanging up on the way out. That just makes it easier to seat the mag.

Just differences in the stamping. I have a few I have to bang in, and I have a few I don't have to. I just bang everything in and problem solved! If you mill about .010" off the top of your mag catch, it should solve the problems.
