Hey all, I'm having issues with my M4. I started off shooting light fed. tactical buckshot and M4 functioned no problem. It also fed the light load fed slugs.
As of late I've had issues with the shotgun not cycling properly. It will eject the empty shell, but the bolt will not close completely on the next round. All it takes is a light tap and the bolt will close. I even tried 3 in magnums and after 3-4 rounds I had the same problem.
Thanks in advance for the help.
