AEG may have simulated recoil and electronic sound, but it is not realism. The charging handle don't work, bolt does not open after last shot. I see so many players pull the charging handle on an AEG before they fire. Why??
The recoil from a GBBR is real because it is the bolt actually cycling, not the gears whining in a gear box and piston slamming back and forth in a gear box like a AEG.
