I recently purchased this gun specifically for CQB, and was not at all disappointed. The feel and ergonomics of the gun are great, and the feeding of magazines and overall rate of fire of the gun make it reliable and easy to use for those familiar with an M-16/M4 weapon system. The easy access to the hop up adjustment is nice, and I really like the finish. What is interesting is the the 350FPS limit is achieved by porting the cylinder rather than using a lighter spring. Where this makes the gun fire well and feel very solid it does make the gun kind of loud. I don't think this is as much a problem for CQB play as it might be in the field, and it is a minor annoyance. While I'm talking about field play, this gun COULD be used for field play, but is not as accurate as most field AEGs. At under 50 feel this thing in a tack driver, and really can put BBs on target, but once you get past 70 feet you can really start to see the BBs spread out. I like the gun enough to buy the non-CQB longer version for field play.
Full Metal construction feels very much like the real thing.
Reliable, feeds and cycles very well.
Good rate of fire.
None, just two very minor gripes
A little loud compared to other AEGs
Not really accurate enough for field play (Unfair gripe as thats not what it was designed for)
