This could mark the beginning of another black hole of a AR-15 vs. Mini-14 "argument"...
The AR is likely more accurate, but in my experience the bolt carrier area will eventually, beyond a handful of magazines, junk up with fouling and eventually become hot enough to dry up much of its lube. The mini and gas piston ARs don't. Each is likely to eventually stop, but neither does very quickly.
