20gauge Special Purpose Tru-Choke Choke Tubes Colonial Arms.
Unique Design For Competition Use
External “Special Purpose” Choke Tubes made from high tensile strength e.d.t. 150 carbon steel to withstand the higher pressures created by large shot and the constant pounding of competitive shooting without bulging at the threads or splitting the barrel. If a tube does fail, simply remove and replace with another. Turkey Tubes deliver extra tight patterns when used with heavier charges of large size lead shot. Not for use with steel shot!

Extended Length, Competition Grade Tubes Improve Pattern & Accuracy
Choke constrictions, from Cylinder to X-Full, in .005" (.127mm) increments let you precisely match your load to the shooting conditions. Long tube extends beyond the length of the muzzle, features highly polished interior for less pellet deformation; reduced fliers and tighter patterns. Knurled grasping band speeds installation and removal. Choke constriction is marked on band, no need to remove tube to verify size.
