I just got out of a four-hour game using this gun with a 9.6v 2400 mAh battery as the only functional modification (i had an AFG, but that's mostly irrelevant) and I must say for an SRC it performed better than expected.
The rate of fire on this gun was nothing special, but the stock barrel still shot with decent accuracy once i adjusted the hop-up, which works perfectly. I wasn't at any disadvantage using this gun in both CQB and Field environments, althought i played mostly in the field (it clocks in at just under 350 fps)
The external build is all ABS polymer, but it feels really good and isn't tremendously light. However, the gun is oddly backheavy, especially with my huge nunchuck battery in the stock. When shouldering the gun this isn't a problem, though, and otherwise it looks great and feels very solid, no creaking or wobbly bits. It was a cold day, so my friends thought it was a metal body at first!
I had no problems with the internals of this gun, everything ran smoothly and consistently. Not the nicest noise from the gearbox, or any exceptional performance, but for medium ranges, expecially firing semi-auto, this gun won't hold you back.
I would recommend this to anybody looking to get into competitive airsoft and looking for a gun that's a bit better than "entry level," however a better choice would be a G&G combat machine for $20 more, they have a higher rate of fire, last longer, and have some metal parts like the outer barrel that come in handy as far as durability goes. If you're dead-set on the full-stock with RIS model, though, this is your best bet for a well-priced starter gun. there's nothing wrong with it.
-Really solid build for an all-poly, nothing wiggles and it looks and feels great.
-Fires with pretty good accuracy once you mess with the hop-up. rear sight is adjustable right/left
-No apparent issues, put up with 4 hours of play using a 9.6v in 50 degrees and some rain
-This style of gun is good for transitioning between CQB and Field
-Fires under 350FPS so it's CQB ready
-Polymer body can break, pot metal gearbox won't last forever
-Stock magazine is pretty cheap (it does work just fine, however)
-Weirdly back-heavy, especially with a large battery (lots of polymer in the stock, very little in the front)
-Easily outperformed by the only $20 more expensive G&G Combat Machine series
