Designed for the serious competitive shooter who desires the optimum of patterns, shooting comfort (recoil reduction) and will fit over/unders, double barrel and single barrel shotguns. Colonial Extended Ported Choke Tubes extend 2" past the muzzle and are blued. For Lead and Numbered Steel Shot. For Steel Shot use, no tighter than a Modified Constriction is recommended. When using Steel Shot, constrictions will be two constrictions tighter than marked on choke tube. Made in the USA...
Note:
Constrictions can be found under the "Other Details" tab.

Purchased a pair of these for my Browning cynergy sporter. Patterns at least as well as the browning chokes - I didn't have problem with the factory chokes I got these for the porting. The porting reduces felt recoil and muzzle flip noticeably - makes a big difference over a days shooting, and for those second shots the reduction in muzzle flip makes target aquisition much easier.
