Ok, I can't quick strip a spring. AKs don't break like ARs either. This a purpose built CQB gun. I wont exceed 350FPS. This is $500 total w/ mags not $1500 w/o mags. Systema is an innovator. I love and buy their stuff, but your would not want this in your AEG?
Cycle completion - AEG piston will perform a full cycle even when you release the trigger early. It'll stop only when it detects a piston strike AND the trigger is not pressed. Very realistic since real guns will always fire one shot no matter how quickly you tap the trigger.
forgot about low voltage shut off
the AEG shuts off if ROF drops bellow 10rps.
Yes and no. It cuts off when it doesn't sense ammo. If you had a hicap you would have to wind it and charge the bolt. If you have mid or low caps you would need to change a mag and charge the bolt. Charging the bolt resets the anti-dry fire circuit and enables the user the continue to fire.
