Description
This is Carlson's Improved Cylinder replacement choke built on the standard Tru-Choke thread pattern, the .795-44 tpi setup found on plenty of Remington Spartan, Baikal, and older Ithaca 12-gauge shotguns. It sits flush with the muzzle, so there's nothing sticking out to snag on brush or your gun case, and it drops your bore constriction just slightly to keep your pattern open. Carlson's runs a lifetime warranty on their tubes, which tells you something about how they're built.
Where the Tru-Choke Improved Cylinder Earns Its Keep
Improved Cylinder is the sweet spot for close, fast shooting. It shines in that 20 to 35 yard window, which makes it a go-to for upland birds like quail, grouse, and dove, plus early-season pheasant that flush right off your boots. Duck hunters working birds over decoys lean on it too, since most of those shots happen inside 30 yards. With just a touch of constriction, you get a wider, more forgiving pattern that helps you connect on birds that are close and moving quick.
Steel, Lead, and What Fits the Tru-Choke 12GA IC
Carlson's machines these from 17-4 heat-treated stainless steel, the same corrosion-resistant material that holds up to heavy steel loads better than a lot of the softer factory tubes out there. This Improved Cylinder is rated for lead, steel, and Hevi-Shot, so you can run it hard through waterfowl season and not baby it. One thing worth remembering: steel patterns tighter than lead, so an IC choke stuffed with steel often throws a pattern closer to what a Modified would give you with lead. That's actually handy to know when you're picking loads.
Before you commit to it in the field, pattern your gun with the exact load you plan to shoot. Every barrel and shell combo behaves a little differently, and a few minutes on paper tells you exactly what you're working with.

Frequently Asked Questions
Which shotguns does the Tru-Choke 12GA Improved Cylinder fit?
This choke uses the standard Tru-Choke thread pattern, which is .795 diameter with 44 threads per inch. It interchanges with 12-gauge shotguns cut for Tru-Choke, including many Remington Spartan, Baikal, and older Ithaca models. If you're not sure what your barrel is threaded for, check Carlson's interchange chart or measure your existing tube before ordering.
Can I shoot steel shot through this Improved Cylinder choke?
Yes. It's machined from 17-4 heat-treated stainless steel and rated for lead, steel, and Hevi-Shot. Keep in mind steel patterns tighter than lead, so an Improved Cylinder with steel loads often throws a pattern closer to a Modified, which is worth factoring in when you pick your shells.
What's the best use for an Improved Cylinder choke?
Improved Cylinder is built for close, fast shooting, generally inside 20 to 35 yards. It's a solid pick for upland birds like quail, grouse, and dove, and it works great for ducks decoying in close. The slightly open pattern gives you more forgiveness on birds that flush quick and move erratically.
Does this Tru-Choke tube sit flush with the barrel?
It does. This is a flush mount design, so it seats level with the muzzle with nothing extending past the end of the barrel. That keeps it snag-free in heavy cover and makes it easy to store your shotgun in a case without a protruding tube.
