Browning 1133883 Invector-DS 20Gauge Improved Cylinder Extended Stainless Steel
$45.46
The Browning Invector-DS 20-gauge improved cylinder extended choke tube in stainless steel is a premium aftermarket choke option for Browning shotguns equipped with the Invector-DS system. Built from stainless steel for corrosion resistance and durability in wet field conditions, this extended choke tube gives you a quick-swap way to fine-tune your shot pattern for different hunting scenarios—from upland birds to clay shooting—without the expense of replacing barrel sections.
The improved cylinder constriction sits between the open cylinder and modified patterns, making it a versatile middle-ground choice for close to mid-range shooting. The extended design makes removal and installation faster and easier in the field, and the stainless construction means you won't worry about rust or surface degradation whether you're hunting in coastal salt spray or the humid Southeast. This is genuine Browning engineering, not an off-brand knockoff, so you know the fit and function are dead-on in any compatible Invector-DS shotgun.
If you run multiple Browning shotguns with Invector-DS threads or just want to have a backup choke on hand, this is a solid add-piece to your shotgun locker. Whether you're working through a pheasant patch, shooting clay targets, or adapting your gun to different shot shells and ranges, swapping out chokes beats hauling multiple barrels to the range or field.

Frequently Asked Questions
Will this choke tube fit my Browning shotgun?
This choke is threaded for the Invector-DS system. Check your shotgun's barrel to confirm it has Invector-DS threading. If it uses the original Invector or a different brand's system, this tube won't be compatible.
What's the difference between improved cylinder and other choke constrictions?
Improved cylinder is a looser, more open pattern than modified or full chokes, making it good for closer targets and wider shot spread. It sits between cylinder (widest) and modified (tighter), so it's a flexible mid-range option for hunting and clay work.
Why choose stainless steel over standard steel chokes?
Stainless steel resists rust and corrosion, especially useful if you hunt in wet, humid, or coastal conditions. It also holds up better over time with frequent removal and reinstallation.
Is this choke tube brand new, or a replacement?
This is a genuine Browning factory choke tube sold as a standalone part. You can use it as a replacement if you've lost or damaged your original, or as an extra choke to keep on hand for field swaps.
