That is right around the upper range of the nitriding process. Skinny barrels heat up faster, so you expect their accuracy to drop off faster. Based on this article, I would think that the gas system has more to do with parts wear than the barrel length; e.g., a mid-length 16″ would wear the same rate as a 12.5″ mid length system based on the timing between primer strike to direct impingement. Adjustable gas blocks are a way companies have attempted to solve this issue. This is actually my favorite configuration.
