Carter Releases Just B-Cuz with Interchangeable Tension System. We may not need a reason, but couldn't resist the temptation to keep making something great even better. The slight curvature to this three-finger release with a larger index finger hole provides for amazing comfort and high accuracy with every shot. Also, enjoy Carter's Interchangeable Tension System to quickly switch trigger springs with the removal of one case screw. Great for any size hands. You won't be able to keep your paws off this one.
