down2hunt Report post Posted July 30, 2022 Hello, I'm in need of some help before I take my rifle to the shop. Well what is happening is I can load/cycle a round and it fires just fine and the empty casing ejects just fine. What isn't happening is the it wont cycle another round after the first initial round! I tried using a new and different magazines but same results. Any and all help would be greatly appreciated.

AZHOUND Report post Posted July 31, 2022 Has this gun previously cycled well? If so I would start with a good cleaning including the buffer tube/spring. A quick check for the bolt is to fully extend it and stand it on the bolt face. It should stay extended and not collapse. If it collapses it likely has worn gas rings.
