I've noticed a small issue with my rifle recently as I was plinking in my backyard preparing for the upcoming season. Upon cocking the rifle back I noticed a small sliding of the upper receiver. This occurs when I cock the rifle and when I push the bolt back as well. Its a sliding distance of about 1/4 of an inch. Now I don't know if this is a normal thing and if others have experienced this issue, however, I've never had it happen before nor have I experienced it while using other CA M24's in the past.
Could this possible be the retaining screws showing signs of stripping? Or is it something else?
