Browning 1133983 Invector-Plus 12Gauge Improved Cylinder Extended Stainless Steel

The Browning Invector-Plus 12-gauge improved cylinder extended choke tube in stainless steel is a versatile constriction choice for shooters who want effective shot spread without sacrificing pattern density. Built around Browning's proven Invector-Plus system, this extended stainless steel choke delivers the slightly open pattern of improved cylinder constriction — ideal for upland birds, close-range waterfowl, or general-purpose shotgun work where you need faster pellet dispersal than a tighter choke would allow.

The stainless steel construction resists corrosion and holds up to harsh field conditions, whether you're working brushy habitat or wet environments. The extended design provides additional reach and easier manipulation compared to flush-mount tubes, making it simpler to swap in the field or at the bench. If your shotgun uses the Invector-Plus platform, this tube is a straightforward drop-in replacement or supplement to your existing choke collection.

Improved cylinder sits in that middle ground of the choke spectrum — more open than modified or full, tighter than skeet. That makes it a reliable go-to for situations where you're not sure of your exact distance to target, or where you prioritize hitting a moving bird with a broader pattern over tight long-range pellet concentration. Pair it with the right loads, and you'll get dependable patterns across a range of realistic hunting distances.

Frequently Asked Questions

What shotguns is this choke tube compatible with?

This tube is designed for 12-gauge shotguns that use the Browning Invector-Plus choke system. Check your shotgun's documentation or contact the manufacturer to confirm compatibility before purchase.

What is improved cylinder choke best used for?

Improved cylinder provides a wider, more open shot pattern than modified or full chokes, making it well-suited for upland hunting, close-range bird work, and general shooting where you want faster pellet spread and a larger effective hitting area.

Why choose stainless steel over other materials?

Stainless steel resists rust and corrosion, which is especially valuable if you hunt in wet conditions, use your shotgun near water, or store it in humid environments. It's a durable long-term investment for field use.

Is this an extended or flush choke?

This is an extended choke tube, meaning it protrudes slightly from the barrel. Extended tubes are easier to grip and remove in the field, and they make sight picture changes more visible than flush designs.
