I shot a .308 with one last week and it seems really sturdy. Anything made by Troy is going to be a quality product I would imagine. I really prefer round hand guards and have 3 AR's with VTAC's. The ability to put rails only where yo want them is the thing I really like.
Should mount the same as the line of alpha rails utilizing the stock barrel nut. I used to run a 15" alpha rail and it was VERY solid. Every rail I've ever used from Troy has always been top notch and well manufactured.
I'm running a 13" Alpha and it's solid. I've heard reports of the Alpha's coming loose or not being sturdy, but I'm thinking it's operator error. Completely happy with mine.
