Carlsons Carl 41033 Core Brn Invector Plus 12ga Close Range

The Carlson's Core Brown Invector Plus 12ga close range choke tube is a workhorse for hunters and shooters who want a single, versatile constriction that handles everything from upland birds to waterfowl to clay shooting. Part of Carlson's CORE Series—built without compromise on quality—this close range/improved cylinder choke is the first in a three-choke lineup designed to cover the full spectrum of hunting and sport-shooting scenarios. Whether you're new to choke selection or a seasoned hand, the Core Series simplifies the choice by rating each tube's effective range right on the packaging and laser-marked on the choke head itself.

This particular tube excels in close- to mid-range work where an improved cylinder pattern gives you the spread you need without losing pellet density. It handles all shot types—lead, steel, bismuth, Tungsten/TSS, and specialty loads like Hevi-Shot—so you're not locked into one ammunition choice. The brown finish is both functional and classic, and the Invector Plus threading fits 12-gauge shotguns with that choke system. Use it for doves, upland game, ducks, and pheasants when birds are working closer, or rotate it into your clay target rotation for trap and sporting clays courses where tighter constrictions aren't always the answer.

Slugs can be safely used through this close-range tube, though Carlson's recommends reserving slug shooting for the close range/improved cylinder choke only. The yardage chart packed with the choke tells you exactly what to expect: with lead shot, you're looking at 5–20 yards for optimal patterns; with steel, 15–30 yards. That transparency takes the guesswork out of choke selection and lets you match your setup to actual hunting conditions rather than guessing at a counter.

Frequently Asked Questions

What shotguns will this choke tube fit?

The Carlson's Core Brown uses Invector Plus threading, which is Browning's standard choke system. It will fit any 12-gauge shotgun with Invector Plus chokes. Check your shotgun's manual or existing chokes to confirm compatibility before ordering.

Can I use steel shot and other ammo types in this tube?

Yes. The CORE Series is rated for lead, steel, bismuth, Tungsten/TSS, Hevi-Shot, Matrix loads, duplex loads, and blends. You're free to switch ammunition types without changing chokes—one of the real advantages of the CORE design.

What's the difference between this close range tube and the other CORE chokes?

Carlson's CORE Series includes three constrictions: Close Range (improved cylinder) for 5–20 yards with lead/15–30 with steel, Mid-Range (modified) for 20–35 yards with lead/25–45 with steel, and Long Range (full) for 30–45 yards with lead/40+ with steel. Each is laser-marked and packaged with a yardage guide so you can pick the right tool for your distance and game.

Can I use slugs in this choke?

Slugs can be fired through the close range/improved cylinder tube only. They are not recommended in the mid-range or long-range tubes.
