Hello everyone,

I recently started experiencing failure to eject problems once every 25 rounds or so. My empty casings would get crimped by the bolt at the neck of the case (reverse stovepipe). My research on this forum pointed to faulty extractors. I also noticed that when pulling the charging handle, the chambered round ALWAYS stayed chambered.

I bent my extractor towards the center of the bolt, but the problem continued.

I have a 10 round magazine that I converted into a 25 round magazine when I moved into AZ from CA. I noticed that when the magazine is full with 25 rounds, the first couple rounds don't properly load/connect with the bolt!

Before the bolt connects with the round:

What a good connection should look like:

What happens when the 10 round magazine is loaded with 25 rounds overshoots the bolt catch:

I wonder if this is a problem with the bolt, the magazine, or both?

If someone can confirm the 25 round magazines and the 10 round magazines share the same spring, then the magazine is essentially the same as a 25 rounder.

It explains why my FTEs are not connected to the bolt when I pull the charging handle.
