Brownells 3-Gun Extended Choke Tube Set-Winchester & Browning Invector

The Brownells 3-Gun Extended Choke Tube Set for Winchester and Browning Invector shotguns puts three precision-engineered options in your hands for clay and steel competition. Built from 1704 stainless steel, this three-piece set includes Improved Cylinder, Light Modified, and Improved Modified constrictions—the exact spread you need to dial in patterns for every stage of a 3-Gun match. Whether you're burning clays at close range or reaching out to distant steel, swapping tubes takes seconds, and the knurled ends make field changes smooth even under pressure.

These aren't generic chokes. They're engineered to throw tighter, denser patterns than conventional tubes, giving you the performance edge competition demands. Laser markings on both the end and body let you verify constriction at a glance, no guessing in the loading area. The design works equally well with standard shot loads and steel shot, so you're covered across different match formats and practice scenarios.

Like any precision component, pattern your specific shotgun and ammunition combination before match day—different shells behave differently through the same choke. That confidence comes from testing, and these tubes reward the prep work with consistent, reliable performance.

Frequently Asked Questions

Will these choke tubes work with my Browning Invector or Winchester shotgun?

Yes—this set is specifically designed for both Browning Invector and Winchester 12-gauge shotguns with those choke systems.

What ammunition can I use through these tubes?

Standard shot loads and steel shot both work through these chokes. However, do not shoot steel loads faster than 1550 FPS through the Full or Extra Full constrictions, and do not use steel shot larger than BB. Slugs, sabots, and rifled slugs should not be used in any constriction tighter than Improved Cylinder.

Why should I pattern my shotgun with these chokes before competition?

Different ammunition brands throw different patterns through the same choke tube. Testing your specific shotgun and shell combination beforehand ensures you understand exactly how your rig will perform on match day.

How do I know which choke tube to use?

Each tube is laser-marked with its constriction on both the end and body for easy identification. The knurled design makes field changes quick, so you can swap tubes between stages as needed.
