Thanks. I mentioned that in post #68 (that it doesn't reciprocate after all). It's just from the recoil if you put your face too far forward.Charging handle doesn't reciprocate. Make sure it's latched when you close the bolt. There is a little spring loaded latch at the front of the buffer tube.
The less square you are to your target (weak side foot forward more) the more your cheek weld will be forward on the stock and then the charging handle will be close enough to get you because of recoil.
I've got 600 rounds through mine and don't even notice the charging handle when shooting.
