I would highly recommend this gun to anyone. Just used this in a battle and I have no regrets about my buy.
Sturdy as a rock
Not too long, not too short
Good accuracy (with 0.25 gram BB's)
Standard with 450-rnd hi-cap mag, forward vertical grip, low profile scope mount, precision 6.03 barrel, and tri-rails
Hop-up chamber slide makes awesome sound
Fairly affordable price tag compared to other professional-grade AEG's
(Only possible cons, as I haven't found anything about the gun that makes me regret guying it)
Small battery compartment doesn't fit higher capacity batteries (not a terrible con if you have extra batteries)
No collapsible stock version (aftermarket stock available)
Scope mount isn't QD (iron sights see easily over it, so there's no problem if you have a QD scope)
Not as many aftermarket products as M4/M16, AK, and G36 models.
