Floor plate popping off

[boomer25]

Problem solved. It was the follower. I appreciate all of the input. Thanks again

It has the same issue regardless of which position the switch is in. Basically, I can load one round into the magazine, but not anymore and the round will not chamber, the bolt goes forward about an inch and stops with the round angled to the left. Should the bolt hit against the rear of the magazine follower when in the On position? Mine does and it almost looks like the rear portion of the follower is slightly higher than the front.

I had a similar problem with my Mark I.
The spring for the follower was not installed properly and
caused the last round to not feed and jammed as you say
yours does.

If the spring is fully inserted in the follower and floor plate,
is it bent? A misalignment of the follower makes or breaks
the feeding of rounds.

Also look at the extractor. If the bottom part of the hook is
bent, it might cause the round to pop out, rather than slide
into position on the bolt face. If you have access to another
bolt, or follower spring, you might be able to get a good
comparison to figure out the problem.

I hope you can figure it out, if not, a video of the chambering
of the offending round might help.

On my Mark I, someone ground the follower so the bolt would
not lock when the magazine was empty. While it was convenient,
I did not like the modification. But it was not the cause of my
jammed round, like I thought it was.
