I shoot one shot the gun cycles but doesn't pick up a round so I pull the charging handle back let it go and it then picks up the round. It does this every shot. I've tried 4) types of ammo and 4) mags that all work fine in my A2 so I'm sure it's not the ammo or mags.
Any ideas what I should check 1st?
