Carlsons CORE Choke Tube Features The Carlsons CORE Series choke tube is engineered around a mid-range modified constriction that bridges close and long-range shooting making it a practical everyday choice for hunters who move between dove fields and duck blinds in the same season. Its compatibility with shot sizes BB through 10 across steel lead bismuth TSS and Hevi-Shot loads means a single tube can handle a wide range of hunting and target scenarios without swapping chokes. The constriction rating is lasered onto the choke head itself so shooters can confirm the tube they are running without pulling out a reference chart. This versatility reduces the need to carry multiple chokes afield. Built from durable steel construction the choke threads directly into Browning Invector Plus pattern barrels for a precise factory fit with no modification needed. The finish is designed to hold up to repeated firing of high-volume loads common in waterfowl and upland hunting. A printed yardage chart on the packaging helps new shooters match choke selection to their intended range and shot type. For Browning shotgun owners looking for one reliable well-marked choke for varied hunting conditions this CORE tube is a straightforward upgrade.
