Theres also issues with the selector switch but that may be due to the cut-off lever not engaging with the micro switch. The novritsch body has dynamat soundproofing and accoustic foam inside because i wanted to build a niche silent aeg. No mag release since i keep breaking the oem plastic ones and I'm too poor to buy the laylax one. The gearbox plate is also a bit tricky to install, just push down until the "fin" of the plate is barely visible so the screws can actually align with the inserts. This AEG is barely functioning at best. Buy at your own risk.
