I'm thinking about this claim that bump firing can lead to out of battery firing and I'm having trouble seeing the mechanism that leads to that outcome.

In order complete a successful bump fire cycle, you need to allow the trigger to reset, then trip it again utilizing the momentum generated by recoil to move the firearm away from your finger (rather than vice versa), resetting the trigger, then using the constant counterpressure on the forearm to move the firearm towards your finger, tripping the trigger.

Assuming your firearm is functioning correctly, this should produce 1 of two results. The rifle goes into battery and tripping the trigger produces another cycle OR you rush the cyclic rate of the firearm and end up pulling the trigger too soon which gives you the same result as standard semi-auto fire--no second shot.

If you can pull the trigger and have the firearm fire out of battery, you run the risk of this happening anytime a round doesn't chamber fully. This is a defect, not a feature.
