A rifled choke tube for 20 gauge smoothbore shotguns, the Carlson's 40021 is purpose-built to stabilize slugs and tighten groups from barrels that weren't designed for precision shooting. If you run a 20 gauge Remington Rem-Choke shotgun for deer or other slug hunting, swapping in a rifled tube is one of the simplest upgrades you can make—no gunsmithing, no special tools. The gentle right-hand rifling imparts just enough spin to steady the projectile without over-stressing the firearm or requiring choke-compatible ammo.
Built from 304 stainless steel, this tube handles the pressure and corrosion that come with hard use in the field. The matte black finish resists glare and blends with most shotgun furniture. At roughly one inch of protrusion, the 40021 fits cleanly and won't snag on brush or gear during the hunt.
Carlson's has built a reputation on tight tolerances and consistent performance. This rifled choke delivers measurable improvement in slug accuracy from smoothbore tubes—particularly valuable if your shotgun wasn't originally designed for dedicated slug work. Drop it in, pattern it, and hunt with confidence.

The Carlson's 40021 is designed for 20 gauge Remington Rem-Choke shotguns. Check your shotgun's choke system before ordering—if you have a different choke pattern or gauge, this tube won't fit.
A rifled choke applies a gentle spin to the slug as it exits the barrel, improving stability and accuracy without placing excessive stress on the gun. Smooth chokes work fine for bird shot or general use, but a rifled tube is the better choice for slug hunting if your shotgun has a smoothbore barrel.
The 40021 extends approximately 1 inch from the muzzle, keeping the profile compact and minimizing the risk of catching on gear or brush in the field.
The Carlson's 40021 is manufactured from 304 stainless steel, which provides excellent corrosion resistance and durability under repeated use and exposure to the elements.
