Bull barrel & nut assemblies are 1-1/8" diameter, and available in 6", (6" is the most requested length) 7",
and 8" lengths. Other lengths can be made to order. The extra mass heats slower and offers additional muzzle
dampening. These barrels install and remove as a one-piece unit and are retained by the barrel nut latch as
are the standard barrel & shroud assemblies.
