First time out with my Grendel I loaded one round, shot, and kept opening gas block until bolt carrier locks back on empty magazine. Then I opened it another 180 degrees.
Today was the second time shooting it. Loaded mags with 4 or 5 rounds, ejected rounds had dented case mouths and the carrier wouldn't lock open on empty magazine every time. About every other time the carrier would eject the round but would slide forward and close on an empty chamber. When I pulled the charging handle to the rear it would lock back.
I assume I need to open the gas block more?
How do you know when you have it right? Can you open it too much and how can you tell?
