The Stanislawski OnneX Hinge Release features an extremely crisp and adjustable sear system and the ability to configure 2, 3, and 4 finger shooting options. This well built release provides loads of adjustability and adaptability to your shooting style while providing unmatched accuracy and consistency. Archers can quickly change the release between 2, 3, and 4 finger configurations via a simple 5/64” screw. The included Stan trainer locking screws allows the user to disable the actual firing mechanism while still being able to use the release. This is a great feature for initially setting up the release and extended practice in real world conditions. The OnneX Hinge Release features adjustable finger sweep and thumb pegs for a custom feel. Each OnneX handle will allow a hunter to change between the three handle styles seamlessly without changing anchor point or peep height. Each OnneX Hinge Release comes with a three and four finger attachment, large and small barrels, and two barrel extensions.
