I got that price $1500 from both Robarm and a local dealer who actually had one on hand. The price is a little steep for a design not tested by any military. On the other hand, without a military organization paying for the development, they've got to recoup it somehow.
I got to handle one at the Pomona gunshow a few months ago. It's pretty nice in both look and feel. The bolt appeared to be a modified AR bolt that lacked the plunger-type ejector. The ejector is an integral part of the receiver's left rail, so you can expect the empties to get out of the way in a hurry. The controls are basically the same as an AR. All in all, it felt like a well made rifle.
