Yep, that's my main rifle now.
I'm building a second lightweight AR from a BCM upper ... but it's kind of on the back burner for now.
I had a M93B before this UBR, the UBR is a much nicer stock.
The "BAD" is a fake, as the real BADs don't exist yet I don't think, but this one is bad ass, it's one piece welded, a complete replacement bolt release. It makes bolt carrier manipulation a dream.
I'd get the MBUS sights ... I had Troys on my last rifle, and they certainly are nice, but for something you almost never use I see no reason to spend $250+ on a pair of sights when you could spend $100 and get a lighter, cooler looking product that functions just as well.
Scout lights are great, buy your from Unobtanium if you're getting one lol, he has been trying to sell his LNIB one for ages IIRC.
