The Carlsons 51203 Remington flush choke tube in 20-gauge Modified constriction is a drop-in replacement for Remington shotguns equipped with Rem Choke threads. Built from 17-4 heat-treated stainless steel, this choke delivers consistent, reliable performance whether you're shooting steel, lead, or premium loads like Hevi-Shot. The flush-mount design keeps your sight picture clean and your shotgun's profile sleek—a practical choice for hunters and sport shooters who demand durability without fuss.
Modified constriction strikes a useful middle ground between tighter full chokes and more open improved cylinder tubes, making it versatile enough for upland birds, waterfowl, and clay shooting across a range of distances and shot sizes. Since it's manufactured in the USA and backed by Carlson's Lifetime Warranty, you're investing in a choke tube built to outlast the shotgun it's installed in.
Compatibility is straightforward: this choke fits Remington shotguns with the standard Rem Choke system. Steel shot larger than #BB or velocities exceeding 1550 fps should not be used in chokes tighter than full, and if you're running a turkey-specific load, stick to steel shot #4 or larger. Beyond those guidelines, this is a no-fuss upgrade for 20-gauge shooters who want a quality American-made choke at a fair value.
