Browning 1133663 Invector-DS 12Gauge Improved Modified Extended Stainless Steel
$45.46
The Browning Invector-DS 12-gauge improved modified extended choke tube in stainless steel is a precision-engineered component for shooters who demand tighter patterns and long-range performance. Built on Browning's proven Invector-DS platform, this choke delivers the constriction needed for extended-range hunting and clay shooting, with stainless steel construction that resists corrosion and handles harsh field conditions without degradation. Whether you're reaching out on ducks, geese, or upland game, or running lead downrange at the range, this choke swap takes seconds and transforms your shotgun's effective range.
Improved modified constriction concentrates your shot column tighter than a modified choke alone, giving you denser patterns at 40+ yards—ideal for long-range waterfowl work or when birds are flaring high. The extended profile stays flush or protrudes slightly from the muzzle depending on your barrel, providing easier handling and a positive grip for quick changes in the field. Stainless steel doesn't rust, doesn't patina, and won't corrode even after a season of wet conditions or saltwater shooting.
If you run a Browning shotgun with Invector-DS threads, this choke is a drop-in upgrade. Keep a few in your vest or truck to match your distance, cover, and game—moving from modified to improved modified is a one-handed job that takes less time than reloading.

Frequently Asked Questions
Will this choke fit my Browning shotgun?
This choke is threaded for Browning's Invector-DS system. Confirm your shotgun barrel has Invector-DS threads before ordering. If you're unsure, check your owner's manual or contact Browning customer service with your model number.
What's the difference between improved modified and modified choke constriction?
Improved modified is one constriction tighter than modified, meaning your shot spreads less and patterns stay denser longer downrange. Choose it when you need reach—long-distance waterfowl, passing shots, or when birds are working at extended range.
Why stainless steel for a shotgun choke?
Stainless steel resists rust and corrosion from moisture, powder residue, and field use far better than blued or plain steel. In wet conditions or after saltwater exposure, it maintains its integrity and appearance without maintenance.
Is this choke easy to change in the field?
Yes. Invector-DS chokes unscrew and install by hand with no tools. You can swap constrictions in seconds to match your distance or target, making it practical to carry multiple tubes in your vest or truck.
