This is a great gun all in all. With only minor deficiencies. But pros:This thing is accurate. With a fully charged battery that it comes with, mine sgit at 432fps. And with just half the battery life gone, it still shot 390.The hopup is very effective and barely needs adjustment once it is set. Maybe every 3000 rounds you should adjust it. The fire rate is also great. Although, if you get a 9.6v battery (tenergy works best) it will up the fire rate just a little enough to be very significant. The rails fit almost any attachment. I put a laser on this and a grip just to get the accuracy even better. It has a 14mm threaded tip if you take the orange tip off. Its good for tracer units and silencers. The kick is also pretty good. And upgrading it was east. The grip feels amazing and also the grip spot by the magazine well is super handy when you are just at the low ready position waiting for games to start.Cons:The sights kinda suck. Bad. Lol. But eh, you get what you pay for. The select fire will mess up sometimes. I can be on semi and it will start shooting full auto, or while shooting semi, it will stop firing and I have to switch from full auto back to semi. With the regurlar battery, if you extend the buttstock and try to collapse it again, it won't collapse past the 3rd extension setting.BUT!Other than that, all around its a great gun. Has great range even with .25's. So if you need a cheap, quality alternative to start with or just to actually use long term, this is it.BUY IT!
