T.R.U. Ball® proudly presents this special edition of our award-winning Assassin, now bearing the iconic Bone Collector™ banner. The Bone Collector™ Assassin XT stands as one of the toughest, top-tier dual caliper release on the market today. Engineered with a durable 6061 aircraft-grade aluminum body and enhanced with a textured design, it combines rugged jaws and a precision trigger to deliver a crisp, consistent release with exceptional long-term reliability.

Engineered for you:

Fully Independent Standard Caliper Jaws: Pull the trigger to open, let up to close. It’s that simple. The fully-independent jaws silently close to load, ensuring the d-loop releases smoothly and evenly through the jaws as they open. This design minimizes torque, promoting a cleaner, more consistent shot. Each set of jaws is professionally tested before packaging to ensure you receive nothing but the best in performance and reliability.

X-tra Tough Grip: Stay locked in from draw to release with the T.R.U. Ball® X-Tra Tough grip. Designed for rugged performance and unwavering control, this textured grip ensures you never lose your grip—just your excuses.

Solid In-line Body Connection: Designed for alignment and feel, the solid body bridges the gap from wrist to jaw—guiding your hand into a straight, steady path to the target. It promotes natural, consistent form so you stay locked in by feel alone.

Globo Swivel Connection: Experience maximum mobility without sacrificing security. The T.R.U. Ball® Globo-Swivel features a solid steel round connector housed in a durable wrist strap mount. Easily adjustable in 3/16" increments to fit various finger lengths, then locked in place with dual screws—so your settings stay rock-solid, shot after shot.

Travel Adjustment: A single adjustment screw allows you to set the exact distance the trigger must travel before activation, giving you full control over your release responsiveness.

Available with a Black Leather or Black Velcro® Strap.

Velcro® Strap: Offering infinite adjustability and the reliable hold of Velcro®, this strap is perfect for growing archers or anyone who prefers a custom, snug fit that stays secure shot after shot.
