Stan SX4 Thumb Release

The SX4 is built to fire the second your brain says "go." No drag, no delay—just a lightning-fast trigger that breaks before anything can mess up your shot.

Hunt long enough and you know tiny mistakes can cost big. The SX4 uses a spring-assisted hook that snaps back to the exact same spot every single time. It takes micro-flinches out of the equation and gives you a clean, repeatable release when the pressure is on. You can adjust the thumb post, tension, trigger travel, and finger feel to fit your hand like a glove. Best of all, it's packed with heavy-duty T10 Torx screws so you can lock in your settings without stripping out the heads in the woods.
