Description
The Carlson's 52213 is a Modified constriction flush choke tube built for 12 gauge shotguns running the Win Choke thread pattern. Modified is the one to reach for when you don't know exactly what the day holds. It splits the difference between an open and a tight choke, holding a workable pattern out to roughly 40 yards, which makes it a solid pick for pheasant, dove, mid-range sporting clays, and general field work. If you could only keep one choke in the barrel, a lot of folks would tell you this is the one.
What Sets the Carlson's 52213 Apart
Every Carlson's flush tube is CNC machined from solid 17-4 PH heat-treated stainless steel bars, so it stands up to moisture and rough conditions without pitting. This one is compatible with both lead and steel shot, giving you flexibility whether you're breaking clays or chasing birds. It sits flush with the muzzle for a clean look and no snag points, and the .710 diameter delivers that classic Modified restriction. Carlson's backs the tube with a lifetime warranty, so if it ever takes damage you can send it back for a replacement.
Fitting the Carlson's Winchester Flush Choke
The Win Choke thread on this tube is one of the more widely shared standards out there. It's compatible with many Winchester, Mossberg 500, Browning Invector, Weatherby, and Savage 12 gauge shotguns that use the standard Invector barrel threading. It will not fit newer Winchester models like the SX2, SX3, SX4, or SXP, which use the Invector Plus system. If you're replacing a lost, worn, or damaged factory flush tube, this is a straight swap that gets you back in business.
Before you head out, it's worth patterning your gun on paper with the exact load you plan to shoot. Every barrel throws a slightly different pattern, and a few minutes at the range tells you exactly where your pellets are landing.

Frequently Asked Questions
What shotguns does the Carlson's 52213 choke tube fit?
This tube uses the Win Choke thread pattern, which is shared across a lot of shotguns. It fits many 12 gauge Winchester, Mossberg 500, Browning Invector, Weatherby, and Savage models that use the standard Invector threading. Keep in mind it will not fit Invector Plus guns like the Winchester SX2, SX3, SX4, or SXP.
Can I shoot steel shot through this Modified choke?
Yes. This flush Modified tube is rated for both lead and steel shot, so you can move from clays to waterfowl loads without swapping tubes. Carlson's does note steel shot should not be run through any of their turkey choke tubes, but this Modified is good to go.
What is a Modified choke best used for?
Modified is the do-everything choke. It holds a useful pattern out to around 40 yards, which covers pheasant, dove, mid-range sporting clays, and general upland and field hunting. If you want one tube that handles a little of everything, this is the one to leave in the barrel.
How is the Carlson's 52213 built?
It's CNC machined from solid 17-4 PH heat-treated stainless steel, so it resists corrosion and holds up over years of use. The flush design sits even with the muzzle for a clean profile, and Carlson's backs every tube with a lifetime warranty.
