Carlsons CORE Rem Choke Features The Carlsons CORE Series choke tube uses a mid-range modified constriction that bridges close and long-range shooting making it well suited to hunters who move between dove fields duck blinds and sporting clays courses without changing chokes. Its rating for shot sizes BB through 10 across steel lead bismuth TSS and Hevi-Shot loads gives one tube broad versatility across seasons and species. The constriction level is lasered onto the choke head itself letting shooters confirm the tube in hand without consulting a chart. This flexibility reduces the number of chokes a hunter needs to carry afield. Machined from steel construction the choke threads directly into Remington Rem Choke pattern barrels for a precise factory fit with no modification required. It is built to withstand repeated firing of high-volume waterfowl and dove loads without premature wear. A printed yardage chart included on the packaging helps take the guesswork out of choke selection for hunters new to pattern testing. For Remington shotgun owners looking for a reliable well-marked mid-range choke this CORE tube is a practical upgrade.
