Picked one of these up last week after reading some glowing reviews. While I haven’t had the opportunity to shoot it yet, I have to say I’m pretty impressed with the feel, fit, and finish. It weighs under 8 lbs, which is impressive. Includes SA BUIS. I did replace the standard charging handle with a larger-latched Odin Works AR10 one, and I test-fit a Magpul BAD Lever tonight and was happy to find that it fit. So now I can pretty much run it one handed like my SBR. The gas block is adjustable though not as easily as most adjustable gas blocks...it requires swapping out a screw with a long hex wrench. Looking forward to trying it out.
