Carlson's Choke Tubes 40020 Replacement 40020 12 Gauge Rifled 304 Stainless Steel

Carlson's rifled choke tubes for 12 gauge shotguns are engineered to transform how your smoothbore slug gun performs. If you're running a Remington rem-Choke shotgun and want tighter groups and more consistent slug accuracy, a quality rifled choke is one of the simplest upgrades you can make. This 40020 model combines 304 stainless steel construction with a precision 1:35 right-hand rifle twist that imparts just enough spin to stabilize slugs without imposing stress on your barrel.

The rifled design works by adding controlled twist to your slug's flight, improving accuracy and group size compared to shooting through a smoothbore alone. Because these tubes are manufactured to tight tolerances from high-stress stainless steel, they deliver consistent performance season after season. The matte black finish won't snag on gear, and the tube extends approximately 1 inch from the barrel when installed, keeping your sight picture and handling characteristics predictable.

Whether you're hunting whitetail with slugs, running accuracy drills at the range, or dialing in your shotgun's ballistics, a dedicated rifled choke gives you measurable control over your shot placement. Carlson's reputation in the choke tube market comes from this kind of no-nonsense engineering—precision steel, proven design, and the durability to last through years of serious use.
