NOT KNOWN FACTUAL STATEMENTS ABOUT KAC CARBINE RAIL

Accuracy/precision testing of this barrel was performed after a 200 round break-in time period.  All taking pictures was finished from my bench-relaxation established-up pursuing my typical protocol.only one facts position, I picked up a few salty used P&S M4 RAS's from Thoroughbred for $one hundred fifty ea. yeah, not KAC, but good enough for me.
