Excalibur - THE Guardian Anti-Dryfire Scope Mount

Excalibur incorporates the Guardian Anti-Dry-Fire Technology into the crossbows of the Matrix 380 Series; This system is designed to catch the string if it is accidentally released without an arrow loaded in the crossbow. The Guardian Anti-Dry-Fire System is designed to catch the string when the crossbow is fired without an arrow loaded, allowing for easy de-cocking. In the event that the crossbow is fired without an arrow, the Guardian System, a self-contained unit housed in the crossbow's scope mount, catches the string and prevents the crossbow from dry firing, thus avoiding potential damage. In addition, it has a built-in trigger, allowing you to easily relax your crossbow at the end of the hunt, unlike other anti-dry fire systems, without having to shoot an arrow - a major advantage. The Guardian System is included as standard equipment on some Excalibur Matrix models and is available as an upgrade kit for all other Excalibur crossbow models
