1. Why the MUR upper receiver? Not that I mind, because I've had a VIS upper before and I love VLTOR's stuff. It's pretty rigid and would be more suited for a precision build. You could save an ounce or two and some money.
2. The Noveske 10.5" barrel is nice. However, I've seen on four separate instances (with three difference Noveske 10.5" barrel rifles) where when shooting suppressed, the tight tolerances and chamber of the barrel caused popped primers.
Still, nice rifle you're putting together, sir.
