Bottom line, they are absolute crap. It is a 702 action inside a cheap, flimsy plastic shell that is in 2 pieces, split down the middle. If you use a sling-supported position, it will pull the 2 pieces apart, and you'll see a big crack of daylight down your front sight post. this pulls your front sight over quite a bit, and really messes with your accuracy. The fact that the sights are not attached to the barreled action is a big minus. The sights also do not use AR parts... the front isn't even adjustable, and the rear just adjusts with big coarse-thread plastic screws with no clicks or anything. The stock is pinned in place. The controls are not anything like an AR anyway, so I don't know what advantage this design is supposed to have other than looking cool to little kids or something.
I've seen one in action at an Appleseed, and the poor shooter couldn't get 20 MOA out of it. He was all over the page because of the magic moving front sight.
