The Sightmark .50 Caliber Premium Laser Boresight (brand part no. SM39012) chambers directly into a .50 caliber rifle for fast, accurate sight-in without expending big-bore ammunition. 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.

Frequently Asked Questions

Why use a boresight on a .50 caliber rifle specifically? Big-bore ammunition is expensive, so getting close to zero on the bench with a boresight before live fire saves both time and money.

Do I still need to fire the rifle after boresighting? Yes, live fire is still needed to fine-tune the zero and compensate for bullet drop at distance.
