Well, let's be real here.
PE is using the 'cork in a bottle' system for the bolt/firing system. Same as an Automag. They even look the same:
The bolt return system is 100% the same. The firing system (including the low speed/high speed stroke) is roughly the same.
The only difference is that PE is doing it electronically versus AGD doing it mechanically.
