If it’s similar design to the black aces, you’ll also want to keep the gas piston and barrel ports clean at the front end of the gun. Mine were notably dirty after just 100 rounds. Hadn’t malfunctioned yet, but were dirty enough that I cleaned them up.
For newbs like I was on a semi auto shotgun: after the bang, the gas piston action unlocks the breech so the recoil can then cycle the bolt and swap the old shell for the new one. I had no idea how any of it worked until I got one.
