Nice quality and finish on the 15" - TacFire A.C.E Series M-Lok Free Float Handguard

I'm very happy with the quality of the machining and finish. The black is deep black, no purple hue. I do wish barrel nut diameters were standardized though. I was hoping I would be able to simply remove the handguard and replace it with this. There was just enough difference in the barrel nut diameter that it would have been loose, so I had to swap barrel nuts with the one that came with this handguard. Not a big deal.
