Browning Invector-Plus 20 Gauge Modified Flush Choke Tube - 17-4 Stainless Steel

If you're running a Browning shotgun with a back-bored barrel and want to fine-tune your shot patterns on 20-gauge game, the Browning Invector-Plus 20 Gauge Modified Flush Choke Tube is your answer. This stainless steel choke delivers the constriction you need for medium-range hunting and clay shooting without the bulk of a traditional extended tube. The flush design sits clean with your barrel's profile, keeping your shotgun balanced and snag-free in brush or from a blind.

Browning engineered Invector-Plus tubes with a longer internal taper to work specifically with back-bored barrels—the result is denser, more uniform shot patterns that let you trust your distances and your aim. The Modified constriction gives you the versatility to handle upland birds, waterfowl, and shooting sports scenarios where you need confidence in your spread. Whether you're rotating tubes to match your hunt or dialing in your setup at the range, having a quality Modified in your kit makes sense.

Durability is built in. The 17-4 stainless steel construction resists corrosion and wear, and the highly polished finish means this tube will perform and look solid for years. Installation is straightforward—it's a direct fit for Invector-Plus shotguns—and the flush-fit design keeps your gun handling as intended, without snags or obstructions. Browning builds to industry standards, so you know constriction is exact and patterns are predictable.

Frequently Asked Questions

Will this Invector-Plus choke fit my Browning shotgun?

Yes, if your shotgun is equipped with Browning Invector-Plus choke threads. This Modified tube is designed as a direct fit for back-bored Invector-Plus barrels. If you're unsure whether your gun has Invector-Plus or a different system, check your manual or contact Browning.

What's the difference between Modified and other constrictions?

Modified constriction is a middle-ground choke—tighter than Improved Cylinder, looser than Full. It provides good pattern density at medium ranges, making it a versatile choice for upland hunting, waterfowl, and clay sports. The exact range depends on your load and pellet size, but Modified typically patterns well from 30–50 yards.

Why does a flush-fit choke matter?

A flush-fit choke tube sits completely inside the barrel, so it doesn't snag on brush, gear, or when mounting and dismounting from a vehicle or stand. It also maintains the gun's original profile and balance, and many hunters prefer the cleaner appearance compared to extended tubes.

Can I use this tube in a non-back-bored barrel?

Invector-Plus tubes are engineered for back-bored barrels. While physical installation may be possible on other barrels, the longer taper inside these tubes is designed specifically to work with back-bored profiles to deliver the pattern quality Browning intended. For non-back-bored barrels, consult Browning's compatibility information.
