Excalibur Guardian Crossbow Anti-Dry Fire System -
Excalibur's Guardian Anti-Dry Fire system prevents dry firing and allows you to easily de-cock your crossbow. If a crossbow equipped with the Guardian is fired without a bolt, it catches the string, preventing possible damage. Another advantage is the Guardian's ability to allow you to safely release the string without having to fire a bolt. Self-contained system is housed inside the crossbow's scope mount. Fits all Excalibur models.
The Guardian Anti-Dry-Fire Technology prevents dry firing and allows easy de-cocking. A self-contained unit housed inside the crossbow’s scope mount, the Guardian system, in the event the crossbow is fired without an arrow, catches the string preventing the crossbow from dry firing, thereby preventing possible damage. The Guardian Anti-Dry-Fire system also features a built-in release so you can easily de-cock your crossbow without having to fire an arrow.
