"I've had this rifle for about three months and its still performing as it did out of the box, which was incredible. I leave welts on my friends with this thing at forty yards, and they swear I'm firing hot when I'm only chrono'd at 365fps.
This rifle is a great base for upgrades too with the lengthy quad rail, although it practically needs none. It accepts paint well, as mine is sitting pretty with a nice desert camo pattern that's been on there for a month and a half now. Single-point slings work great, as it has a sling plate pre-installed. Also comes with an aluminum inner barrel, which is one step up from the standard brass on most AEGs
The battery sits in the 6-point stock, and its pretty simple to hook up once you thread the plug and nunchucks through the removeable template piece in the back. A 450rd hi-cap coming standard is also a plus. Iron sights are standard M16, so I NcStar'd mine with a red/green dot reflex and that alone with the paint tac it out a great deal.
Overall I have more range and power than all my friends, including a $400 full-metal licensed Herstal F2000. No mechanical problems at all and none foreseeable.
Sorry if I seem like a fanboy for this rifle, but it has just been that good to me. 5 stars."
