STAN Onnex releases are designed with legacy features that archers should have integrated into the complete shooting system. Each Onnex handle will allow the shooter to switch between one of three handle types, thumb button, back tension, and resistance seamlessly while maintaining anchor point and sight height. Open hook design for consistent and accurate side travel. Crisp break trigger with independent trigger travel and trigger tension adjustments. Loop retainer allows connection to your bow with the unique open hook, while keeping your release connected. Available in multiple sizes to comfortably fit any archers hand. Built on a modular body, the release can be triggered as two finger, three finger, or four finger all with a 5/64" allen wrench button head screw adjustment. Includes two length barrel posts, one long and one short, as well as two small and large barrel sizes for a perfect fit to the hand. STAN Trainer Lock feature allows for practicing trigger activation without actually shooting.
