Thinking about buying this mount that clamps on the tube, but they make 2 styles, anybody got this and how do you like it?

I just put one on my M&P15OR tonight. Picked it up at Cabela's yesterday. It seems like a quality piece, made of aluminum. As I tightened the allen head down that pinches it together I had to remind myself not to overtighten it and strip the threads. With a little blue Loctite I can't imagine it ever loosening enough to slide which would be the only failure it could have. I also bought the CAA one point sling. I like the looks and feel of both.
