Excalibur - Insight Scope Level

Tilting the crossbow causes the arrows to not fly straight at longer distances. Excalibur's Anti-Cant INSIGHT SCOPE LEVEL helps you maintain the horizontal axis of your crossbow while the arrow remains on its vertical plane. Its lightweight, unique design can be quickly and easily installed on your rifle scope, allowing the level to be visible through the scope with your peripheral vision. - Suitable for all scopes with diameters from 1.641.55.495.1.641.55" to 1.641.55.495.1.641.5541.58" (41.58mm-41.5mm).
