PROS: This gun has it all here. The price (most important to me, whose parents won't let me spend tons of money on this stuff) is fantastic. The extras (red-dot sight, light, etc.) are cool, too. FPS is nice (although it's terrible for .20s or .25s. Oh, well.).
CONS: Magazine is small (forty rounds), although huge for a spring (I'm too used to my Cybergun AEG, I suppose). No extra one. No bipod (but that's ten bucks, anyway). No sling.
All in all, this is a fabulous gun if you are tired of your AEG's battery running down, and want a back-up (like me). I give it a 5 stars.
