Description
The Carlson's CORE #1 Close Range choke tube is built around one simple idea: make it easy to grab the right constriction and get out shooting. This is the Improved Cylinder end of the CORE lineup, cut to a .720 diameter and threaded for Winchester-style barrels. Instead of decoding a wall of choke symbols, you just read the label. Close Range means open patterns that spread quickly, which is exactly what you want when birds are decoying tight, flushing at your feet, or when you're breaking clays on close, fast presentations.
What the CORE #1 Close Range Choke Does Best
Think of this as your short-yardage tool. Carlson's lists the Close Range constriction for roughly 5 to 20 yards with lead and about 15 to 30 yards with steel, so it shines on decoying ducks, early-season doves, upland flushes, and skeet-style targets where a wider spread gives you more room for error. It's rated for shot sizes BB through 10 and plays nicely with steel, lead, bismuth, TSS, and Hevi-Shot, so you're not locked into one type of load.
Fit and Build of the Winchester CORE Close Range Tube
This tube uses the common Winchester choke thread pattern, which also covers a lot of Browning Invector, Mossberg 500, and Savage shotguns that share those threads. Carlson's machines the CORE Series from 17-4 heat-treated stainless steel, so it holds up to repeated shooting and the abrasion that comes with steel shot. It also carries the Carlson's lifetime warranty, which is a nice bit of peace of mind for a part that lives inside your barrel.
One thing worth knowing: this is a flush-fit close range choke, and slugs should only be run through the Improved Cylinder or Close Range constriction, never anything tighter. Pair it with your favorite short-range load, pattern it on paper at your typical distance, and you'll have a dependable setup for the days when the action happens up close.

Frequently Asked Questions
What is the Close Range #1 choke best used for?
The Close Range #1 is an Improved Cylinder constriction, meaning it throws a wide, quick-opening pattern. It's a great fit for decoying waterfowl, early-season dove, upland birds flushing close, and close-in clay targets. Carlson's lists it for roughly 5 to 20 yards with lead and 15 to 30 yards with steel.
Will this Carlson's choke fit my shotgun?
It uses the Winchester choke thread pattern, which is one of the most common in 12 gauge. That covers many Winchester, Browning Invector, Mossberg 500, and Savage shotguns that share those threads. If you're unsure, check your barrel or owner's manual for the Win Choke or Winchester/Browning Invector marking before ordering.
Can I shoot steel and TSS through this choke?
Yes. This tube is rated for steel, lead, bismuth, TSS, and Hevi-Shot in shot sizes BB through 10, and the 17-4 stainless build stands up to the harder non-toxic loads. If you plan to shoot slugs, note that they should only be run through an Improved Cylinder or Close Range constriction like this one, not anything tighter.
How is the CORE Series different from other Carlson's chokes?
The CORE Series is designed to simplify choke selection with plain labeling: Close Range, Mid-Range, and Long Range instead of confusing symbols. It's aimed at making the right choice obvious for newer shooters while still delivering the quality patterning experienced hunters expect. This #1 is the Close Range option in that lineup.
