Yes the bolt in completly inside. The powerfeed helps the balls to feed faster, on account of the blow back the e-mag will generate. Instead of the balls being blow up the stack above. It just hits the side of the powerfeed and bounces back into the breech. Means less chops and faster feeding. Though people will argue that vertical feeds faster.Originally posted by Arrival
On an E-Mag is the bolt completely inside the marker? What exactly does powerfeed do to it's feed performance?
