Colonial Thin Wall Choke Tubes (Super Steel)

Colonial's tough blued steel extended choke tube is designed to take steel shot abuse, so your barrel doesn't. Steel shot may bulge even the toughest, thickest shotgun barrel at the choke, gradually destroying not only pattern density but the barrel itself. Plus, the battering also jams the choke tube threads into the barrel threads, making removal extremely difficult. Our solution to the problem is Super Steel tubes with the choke beyond the barrel. Made in the USA...

Lead Shot may be shot through the Steel Shot choke tubes. Please note that the constriction will differ. When shooting lead shot through our steel shot chokes, you will get two constrictions more open. For example, the Improved Cylinder Steel Shot will be the same as a Cylinder lead shot; Modified Steel Shot will be the same as an Improved Cylinder lead; Full Steel Shot will be the same as a Modified lead and the Extra Full Steel Shot will be in the neighborhood of an Improved Modified lead.

NOTE:

Constrictions can be found under the "Other Details" tab
