Thanks for all the suggestions. I'll try to get my hands on some new magazines and see how everything works out. I have owned the rifle for 10 months now and have shot about 2500 rounds thru it. I only have 3 magazines and have equally used them from when I first bought the gun.

I noticed the FTEs began after moving to Arizona and the only change I made was converting the blue follower magazines to hold 25 rounds.

My extractor looks clean. Is the extractor supposed to connect with the round while it is being pushed out of the magazine? Or is it supposed to connect after the round has been shoved in the chamber?
