Rage Crossbow X shock collars prevent the blades on your Rage Crossbow X broad head from prematurely deploying if you happen to bump your bolt or broad head while on stand or stalking. Shock collars are designed to break upon impact and will need to be replaced after each shot. Inspect the shock collar for any damage prior to use to ensure proper function. These collars are compatible with Rage Crossbow X models only. 5 pack. Model 62500.
