Description
The Carlson's 50102 is an Improved Cylinder choke tube built for 20 gauge shotguns running the Winchester-style thread pattern. Improved Cylinder is one of the most useful constrictions you can carry, giving you a wider, forgiving pattern that shines on close-flushing upland birds, skeet, and other short-range work where a tighter choke would just make things harder. This one measures a .610 exit diameter, offering a moderate squeeze that tightens things up without choking the spread down too far.
What Makes the 50102 Winchester Choke Worth It
Carlson's cuts these from solid 17-4 PH heat-treated stainless steel, which is the same corrosion-resistant grade you want in a tube that lives inside a barrel through rain, mud, and marsh mornings. The flush-mount design sits level with the muzzle for a clean look and nothing sticking out to snag. A knurled end gives your choke wrench a solid grip, and the constriction is stamped right on the tube so you always know what's loaded before you head out. It's steel and lead shot compatible, so you're not locked into one type of load.
Fitment for the 50102 Improved Cylinder
This tube threads into shotguns using the Winchester/Browning Invector/Mossberg 500 choke system in 20 gauge. That covers a wide swath of Winchester, Mossberg, Browning, Weatherby, and Savage guns, which makes it a smart pickup if you've lost, worn out, or dinged the factory tube that came with your shotgun. Installation is straightforward: make sure the gun is unloaded, lightly lubricate the threads, thread it in with a standard choke wrench, and seat it fully before shooting.
Carlson's has been machining chokes in the USA for over three decades, patterning thousands of load and tube combinations to dial in their designs. Every tube is backed by a lifetime warranty, so if it ever gets damaged you send it back for a replacement. For the money, it's tough to beat a stainless replacement tube from a name this trusted.

Frequently Asked Questions
What shotguns does the Carlson's 50102 choke fit?
It's built for 20 gauge shotguns that use the Winchester-style choke thread, which is the same pattern found on Browning Invector and Mossberg 500 guns. That includes a broad range of Winchester, Mossberg, Browning, Weatherby, and Savage models. If your barrel takes standard Win-Choke tubes, this one will thread right in.
What is Improved Cylinder good for?
Improved Cylinder gives you a wider, more open pattern than Modified or Full, which makes it a great pick for close-range shooting. It's a favorite for upland birds that flush close, skeet, and sporting clay stations where targets are near. At .610 constriction, this tube tightens your pattern just enough to add a little reach without pinching the spread down too far.
Can I shoot steel shot through the 50102 choke?
Yes, this Improved Cylinder tube is rated for both steel and lead shot, so you can run non-toxic waterfowl loads or lead upland and target loads through it. The 17-4 stainless construction handles steel fine at this constriction. Always pattern your specific load to see how it performs before heading out.
How do I install the Carlson's flush choke tube?
Start by making sure the shotgun is completely unloaded. Lightly lubricate the tube threads, then thread it into the barrel by hand and snug it down with a standard choke tube wrench until it's fully seated. The knurled end gives your wrench a good grip, and the constriction is marked on the tube so you can confirm what you've installed.
