Well, let's see what we know (correct me if I'm wrong). You have a number of stocks which fit properly on a number of M1A actions, one of which you traded away. Its replacement won't lock up at all in any of the stocks, which suggests something different, or maybe wrong, with your new old action. I assume it fit OK in the stock your trading partner kept (I bet he's having as much trouble as you are but in the opposite direction of way too sloppy a fit - you might ask him about that). Since you using a NM stock, I assume it's been bedded for the action you traded away but if it'll work as least sort of with your other actions, it's more likely the problem is with the action.
Normally, before trigger group lockup, there's some space under the receiver's heel. When you close the trigger guard and pull the heel down, you're also pulling the barrel and front band up, and that's where the tension at the front band lip comes from. Does this action have an oversized barrel and/or op rod guide that's getting jammed in the fore end of the stock?
