That combination is designed to create more consistent arrow contact and improve downrange accuracy, giving shooters a more repeatable shot.
Another major selling point is the Gear-X Autobrake Drive System, a fully contained crank system that allows hunters to both cock and safely let down the crossbow with minimal effort. The ability to stop and start the crank at any point adds convenience and control, making it especially appealing for hunters who want a simpler, safer system in the stand or blind.
The STX PROSERIES also delivers strong performance numbers, producing speeds up to 405 fps while maintaining a compact profile that’s easy to maneuver in tight hunting situations. At just 6.75 inches cocked, it’s designed for hunters who value both speed and mobility.
Additional features include an adjustable buttstock for a better fit, an anti-dry fire safety system, and a complete accessory package that includes a scope, bolts, quiver, and rail lube. Overall, the STX PROSERIES stands out as a feature-rich, hunt-ready crossbow built for hunters who want premium convenience without sacrificing performance.
