Got mine the other day...
Nice. REEEEEAL NICE. I installed this on my AWO vz in about 20 minutes.
Finish - Not sure what the finish is, but it held up to repeated blows from a plastic hammer used to install the lower half.
Fit - as I said, the lower half had to be coaxed in to position with a plastic hammer. This is a good thing, in my opinion. The more rock solid, the better. The upper half was snug, but needed far less convincing to be fully seated. This is also a good thing, as the operator needs access to the gas piston via the upper half of the handguard.
I don't think that I could be more impressed with the fit & finish of this handguard set. The bad-ass factor is off the chart.
Can't wait to load this mean beast up with a light, red dot, vertical grip, etc.
