Although I haven't fired the weapon yet, I believe the Stag Arms quality is known and the name speaks for itself. I was hesitant to order this model at first because it looked very angular and I wasn't sure I would appreciate the appearance. I know that doesn't matter to some, but it does matter to me a bit. As Mr. Kennedy said, the pictures don't flatter this upper. I was looking for the Diamondhead handguard that I'd seen get many compliments in some reviews. I took quite a bit to verify that this DOES have that handguard. When you see the upper in person, it doesn't have nearly the angular sharpness that it appears to have in the pictures. The underside is more rounded, and there are smooth rounded grooves that are very comfortable to the hand. I believe the VRST in the name refers to the Diamondhead VRS T handgaurd. Search that up for a better view... As for me, I'm more than pleased with my purchase.
