Carlson's flush-mounted choke tubes are designed to fit most shotgun models, offering an ideal replacement for damaged, worn-out or misplaced factory flush-mounted choke tubes. Made from corrosion-resistant 17-4 PH stainless steel, these choke tubes are built for exceptional durability and long-term performance. They are compatible with both steel and lead shot, providing versatility for a range of shooting activities. However, steel shot should not be used in turkey choke tubes. With Carlson's flush-mounted choke tubes, you can rely on consistent, high-quality performance every time you shoot.
