[QUOTE="Fister, post: 800204, member: 7804"] All bushmaster barrels will be marked as such. Also all bushmaster barrels will be chrome lined unless they are stainless. * Only exception will be the Varmiter or Preadator barrels as they are built to be match gun foundations. (as per Bushmaster) To test for chrome lined barrel simply dab a q tip in some gun blue and rub it on the shinny chrome looking part of the chamber. If it blues it its not chrome lined as chrome will not blue. Honestly thats the easiest way. Twist will have to be measure and counted using a cleaning rod and counting the rotations it makes for a given distance. 1-7 = 1 full twist for every 7 inches 1-9 = 1 full twist for every 9 inches [/QUOTE]
