Sightmark .17 HMR Premium Laser Boresight - SM39022

This laser boresight chambers like a standard cartridge and projects a laser dot to show exact rifle aim point, eliminating the need for test firing during initial scope setup. It is compatible with .17 HMR rifles and shotguns of all types. Fine-tuning with live fire is recommended only after bore-in to account for bullet drop and other ballistic variables.
