Things I liked:everything... ; accuracy, power, weight, realism, mag capacity, cost, easy to cock, intimidation factor... unstoppable. Things I would have changed:absolutely nothing. I dare you to find a fault of this gun. What others should know:my friends are terrified of the gun. I'll have owned it for one year tomorrow, and this thing is still unstoppable against any weapon including aegs with cover. I use .2 and .25 gm ammo. not much accuracy difference if you use the hop up system right. Chrono: .20 = 434-452 fps, .25 = 373-390 fps. To get the most out of the gun, get a bipod, sling, extra mags, a speedloader, and of course a scope (you don't have to get the one included, there are better cheaper ones for sale on this site. All can be found in the accessories link by the description. Get this gun. Rivals the best spring guns in airsoft; better than the m234, super 9, m14, or L96.
