Guns, Dogs and Blades QnA

So question to all y’all. I just got a Aero Precision X15 in a trade. It has a 223 Wylde barrel. Anyone have any experience at all with the brand? I have never even had a student in class rock one much less have I ever shot one. Anybody know anything about them? Seems pretty darn well built?
Yay! You can shoot 5.56!
