Invector-Plus — Shotgun Choke Tubes
What is the Invector-Plus Choke Tube System
The Invector-Plus choke tube system maximizes pattern consistency, eliminates flyers, and bests competing choke systems on the market. Engineered specifically for Browning Back-Bored shotgun barrels, this interchangeable system provides competitive shooters and hunters with the exact constriction needed for any target.
How Invector-Plus Systems Outperform the Competition
1. Uniform Densities and Fewer Flyers
The extended taper inside Browning's Invector-Plus choke tube gradually guides the shot column. This reduces pellet deformation, resulting in denser, more reliable shot patterns downrange.
2. Steel Shot Durability
Browning builds Invector-Plus chokes from 17-4 stainless steel. This superior material withstands the extreme pressures of heavy steel shot waterfowl loads.
3. Complete Barrel and Thread Protection
The Invector-Plus design prevents combustion gases from slipping between the choke tube and the barrel threads, making removing and installing the choke tube in the barrel easier.
Difference in Configurations
Browning offers a wide selection of factory configurations tailored to your specific shotgun model and hunting or shooting application.
- Flush Choke Tubes: These sit entirely inside the barrel for a clean look. They come standard with most Browning shotguns.
- Extended Choke Tubes: Extend past the muzzle for quick, tool-free changes. They come standard on select sporting and hunting models and are available as aftermarket upgrades directly from Browning.
- Available Constrictions: Options range from open Cylinder constrictions for close-range skeet up to Extra-Full constrictions for tight turkey and trap patterns.
