I've own this gun for about a year now and it rocks in a CQB environment. Very easy to manuver in a tight environment. When I first bought this I was concerned that it wouldn't be accurate with such a short barrel. It shoots pretty straight for a short barrel. Not as accurate as my longer barreled M14 but good enough. I've put about 24,000 BBs through it and hasn't failed me yet. I
Solid metal build
Small PEQ box
Reliable performance (so far)
Split gearbox makes it much easier to upgrade to a stronger spring like a 120 spring.
The vibration from autofire can cause the knobs on the handle and body pins to vibrate out. I also had one of the PEQ screw pins vibrate out. Just add lock washers to solve this issue.
Doesn't come with battery
One mag failed after about 10,000 rounds.
