Browning 1133263 Invector-DS 12 Gauge Improved Modified Steel Chrome Choke Tube

The Browning Invector-DS 12 Gauge Improved Modified choke tube is a flush-fitting replacement choke built to tighten your shot pattern for mid-range hunting and clay shooting. If you run a Browning shotgun with the Invector-DS threading, this stainless steel tube with chrome finish gives you a durable, corrosion-resistant option that handles steel shot and harsh field conditions without compromising performance or longevity.

Invector-DS chokes have become the standard on modern Browning autoloaders and over-unders, and the Improved Modified constriction sits right in the sweet spot for waterfowl, upland birds, and sport shooting scenarios where you need tighter pellet grouping than a Modified alone would deliver. The flush design keeps your gun clean-lined and snag-free in the blind or brush.

Stainless steel with a hard chrome finish means this tube won't rust out after a season in the marsh or rain-soaked upland cover. It's a straightforward upgrade or backup choke that integrates seamlessly into any compatible Browning shotgun system.

Frequently Asked Questions

Will this choke fit my Browning shotgun?

This choke uses the Invector-DS threading, which is found on most modern Browning autoloaders and over-under shotguns. Check your owner's manual or the existing choke tube to confirm your gun has Invector-DS chokes before ordering.

What's the difference between Improved Modified and other constrictions?

Improved Modified tightens your pattern more than a Modified choke but less than a Full choke. It's ideal for waterfowl, upland game at 30–45 yards, and clay shooting sports where you want denser pellet grouping without over-constricting.

Can I use steel shot with this choke?

Yes, this stainless steel tube is built to handle steel shot ammunition.
