Sightmark 20 Gauge Premium Laser Boresight

The Sightmark 20 Gauge Premium Laser Boresight (brand part no. SM39008) is built to chamber directly into a 20 gauge shotgun for fast, accurate sight-in. The Sightmark Laser Boresight offers a convenient, accurate way to sight in a rifle or shotgun without firing a single live round. Simply chamber the boresight like a regular cartridge and a laser dot shows exactly where the firearm is aiming, so a scope or red dot can be zeroed on a bench before any ammunition is spent. Live fire is then only needed to fine-tune the zero and compensate for factors like bullet drop at distance. Sellmark Corporation includes a lightweight carrying pouch to protect the boresight for repeated field use.
