Developed to fit many models from the top brands in the industry, these tubes come in a variety of capacities from +2 to +6 rounds making them great for waterfowlers chasing snow geese, 3 gunners and home defense applications.

The lightweight low-drag follower is anodized red for high visibility and effortlessly guides the next round toward the receiver. Extension kits are available in either a black Cerakote finish or Realtree Max-5 camo to perfectly match and compliment your shotgun. Select models are available in carbon fiber for ultimate lightweight performance.
