It seems alot of you have AR15's. Have any of you ever had your Bolt Carrier Key become loose while shooting? While sighting in a new red dot this weekend, I started having ejection problems. Field stripped & found the carrier key was loose. tightened it up when I got home and used loctite blue. Suspect this to be the source of my ejection problems as it was cycling fine previously.
