I think they improved it by putting a slightly better rear sight on it and raising the price.
I think more think they're supposed to rival the AR models and that style firearm.
Hmm, doesn't have any of the desireable traits of an AR (durability, accuracy, hi-cap magazines available anywhere) Cost as much as an M1 which again is more accurate, infinately more durable, and shoots a non-mousegun caliber to boot.
