Browning 1130303 Standard Invector 12 Gauge Cylinder Flush Choke Tube - 17-4 Stainless Steel

The Browning Standard Invector 12 gauge cylinder flush choke tube gives you a no-compromise option for wide-open shot patterns on clay courses, in the field, or at the range. If you run a Browning shotgun with Invector choke compatibility, this cylinder constriction delivers minimal pellet deformation and the widest possible spread, making it ideal for fast-moving targets or short-range work where you need maximum coverage rather than tight grouping.

Built from 17-4 stainless steel and polished to a mirror finish, this tube resists corrosion and holds up to repeated use and exposure. The flush-fit design sits flush with the barrel muzzle—no protrusion, no snag, clean aesthetics, and easier gun handling. Browning manufactures all their Invector tubes to industry-standard constriction specs, so you get reliable, repeatable patterns every time you shoot.

Swapping choke tubes lets you tune your shotgun's shot pattern to the task at hand without committing to a single load-out. Keep a cylinder in your bag or truck, mix it with tighter tubes, and adapt on the fly. Whether you're breaking clays, hunting upland birds, or running buckshot for home defense, having the right choke for the job makes a tangible difference in your hit rate and confidence.

Frequently Asked Questions

Will this choke tube fit my Browning shotgun?

This cylinder choke is designed for Browning shotguns equipped with the Standard Invector choke system. Check your owner's manual or the barrel marking to confirm Invector compatibility before ordering.

What's the difference between cylinder and other constrictions?

Cylinder choke produces the widest, most open shot pattern. As constrictions increase (Improved Cylinder, Modified, Full, Extra-Full), patterns tighten and pellets stay grouped longer downrange. Cylinder excels at close range and fast targets.

Does this tube stick out past the barrel?

No. The flush-fit design sits level with the barrel muzzle, giving you a clean profile and easier handling without a protruding tube to snag on brush or gear.

Why stainless steel?

17-4 stainless resists rust, corrosion, and pitting from moisture and repeated cycling, keeping your choke tube functioning smoothly and looking good for years of use.
