Huh? No, you've got that all wrong I'm afraid...
The Hollowpoint won't work because it lacks a method of shutting off the dump chamber section of the firing can during the firing cycle. It relies on the solenoid of the gun's board to perform that action, which is fine for an electro, since the board will close the solenoid automatically after a certain time regardless of what the trigger does. On the eNMEy, the mechanical firing valve will remain open as long as you hold down the trigger, so the bolt itself needs to be able to close the chamber. This is what the 2nd o-ring on the stock bolt's tail does.
Since the L6 still has a tail, with 2 o-rings, it will work in the eNMEy. It is the lack of such a tail and o-rings that is what keeps the L7 and HP from working in the eNMEy. They will install just fine, and even cycle, but you will get inconsistent velocity and efficiency because no human is capable of pulling a trigger for exactly the same amount of time, every time, like an electronic processor can do with a solenoid.
As far as I can tell, the L6 does not seem to lose the anti-chop function. I haven't had any breaks while running it alone (without the QEV installed, granted I'm running a Virtue Spire so outrunning the hopper is not an issue for me), and just yesterday in practice I did have an odd-shaped ball stick in the feedneck a bit and the gun just chuffed. Slapped the hopper to activate the g-sensor and it forced the ball down into the breech and I was able to fire it without breaking it.
I can't say as much for the QEV. After running it for a full 8 hour scenario with the L6/QEV combo, I was getting some chops here and there. Granted, this was with a Kingman Fasta and not the Spire that I run now, so with a forcefeed you might be ok. But I do believe the QEV reduces or entirely eliminates the anti-chop function by allowing the speed of the bolt on the forward stroke to increase. After removing the QEV and going back to a stock front banjo, I have not had a single chop or barrel break in well over 36 hours worth of combined scenario/woods/speedball play.
The question that remains is how well would the QEV fair in combination with the stock bolt. Since the stock bolt is heavier it may not accelerate as fast with the QEV installed as the L6 did and may offer a performance improvement for those who cannot track down an L6. I never had a chance to test my gun in that configuration so I can't give an honest, proven answer.
