This is an excellent gun; the bullpup design is extremely comfortable to hold and makes it practically unstoppable for CQB. Maneuverability is great. It has a standard M4 sized barrel and shoots really well. The guns accuracy will benefit greatly from an upgraded hop up; the hop up may make the BBs curve a bit. However for the size of this rifle it is awesome. Also don't believe the product info section on the FPS; this thing was shooting 371-390 with .20g BBs. I was not expecting that at the chrono. Airsoft GI should really change that. One thing that might put off some people is the plasticy feel to it. It feels really good; no creaks or rattles but it has a lot of plastic. I recommend getting a red dot as well.
All in all I'd say this gun is a killer purchase; I love it and have a hard time choosing between my M14 and my Tavor.

Bad iron sights (Actual gun design; not necessarily S&T's fault)
