The present invention relates to a crossbow scope with a built-in laser rangefinder. The crossbow scope is designed to be integrated to crossbows during crossbows' manufacturing or retrofitted to existing crossbows. The scope is activated using a push button coupled to the scope and positioned on the crossbow. The scope has a laser diode emitting a laser towards a target and a range sensor for determining a range or distance to the target and a tilt of the crossbow relative to the target. Users can adjust their crossbow position to accommodate the laser reticle within the sight to match the laser beam with the target. The scope improves crossbow shot accuracy while hunting, during competition, shooting practice and more.
