I purchased the Lancer Tactical M4 RIS Carbine back in late August, and it has held up considerably well since then. In the about 3 month's I have owned the rifle, only minor problems have arose, all easily fixable. The rifle comes in a box with the standard M4 carrying handle sights, a (really bad) grip, 2 rail covers, and a Ni-MH battery. The box itself has a plastic carrying handle for easy transportation.
Extremely durable polymer - survived many drops
Battery has considerably long life
Very worthwhile rifle overall
Grip pretty substandard, gave to friend
Gearbox can move away from gears, not too hard to fix though
Knob that keeps the stock release in place easily falls off, had to replace that
