Well, it's the VFC MK18 Mod 1, modeled after the guns Spec-Ops use. Functional bolt catch and release which is awesome for adjusting hop-up, and the gun comes two-toned and with a foregrip. All you need is a battery (crane stock type or lipo stick) and you're all set! Despite the fps listed, I chrono'ed at around 360 fps with .25 gram BBs, so with .20s you should get 380-390 fps. Probably a little too hot for cqb so you'll have to change springs. Overall, I'll give this gun a 4.3-5. Why weird number? It's a great quality gun, but it's not halfway to perfect, so I got to bump it down a notch.
Good ROF with a 7.4v LiPo or 9.6v NiMH
Price (relative to everyone, but to me 400 even would've been great)
High cap is not of the greatest quality
Semi auto locks up after 10 or so shots (shoot in full auto for a second to reset it, must be a cut off lever issue)
Crane stock (so overplayed, but gets the job done)
