    1. Good one

      I would definitely recommend this gun, especially for newbies. You get well-working stock gun without a need for additional tuning or adjustments. Easily adjustable hop-up. Easy to clean (barrel etc). It performs really well, very good rate of fire. Better look and feel than SR series. On the bad side, crane-stock is a little bit shaky. It might be also a bit too long for CQB (though it's fine for me personally). I use Li-Po 7.4V 2000mAh 15C battery and it seems to be more than enough. Note that for CQB you might need to downgrade (string replacement) it for CQB, but I'm not sure (depending on a source it's 330-410fps).
