18" ultramatch mod2 .223 wylde barrel missing tin coating - Rainier Arms AR Ultramatch MOD2 .223 Wylde Barrel

The 18" polished stainless barrel I received was missing the "trademark" TiN coating on the barrel extension. Of all of the quality-control things to miss, this would be among the MOST OBVIOUS. I have this same polished stainless barrel in the 16" length from a few years ago and it came about as perfect as it gets. This one seriously makes me question the current levels of quality control on these barrels, as there was literally ZERO way to miss this, if anyone AT ALL was performing a final quality inspection. Now I have to sent it back and wait MONTHS for a replacement.
