Yes it is a good rifle. They are kind of new to rifle building but have made parts for a lot of big time AR-15 company's for a lot of years. I know some of the parts they make for other company's but i am not sure if i can tell
I have three of their lower recivers and one of their new flat top uppers. And they are just as good if not better than most of the other guys out there making parts. I have also been to their factory 3 times now to pick up stuff and they are all nice people and they can make anything you want.
The barrel is most likly a Wilson Arms barrel and the rest of the majior parts are their's and what isn't theirs is most likly Rock River Arms.
Here is a link to thier web site
