I recently purchased a 1903 Mark I from the CMP. It's in great working shape after degreasing except for the fact that the last round out of the magazine won't chamber. If there's just one round in the magazine it hangs up and gets stuck. Enough force will send it home or I can press down on the follower with lots of force to get the round loose.
I've replaced the extractor, that solved another problem where the bolt wouldn't close on a manually inserted round.
The baseplate is stamped B and the follower with an R, here are pictures of the trigger guard/follower/spring setup

Any help is much appreciated, I will happily provide any other pictures that might help.
