Sightmark 7MMX64 BORESIGHT

The Sightmark 7MM x 64 Boresight (model SM39030) is a laser-based alignment tool designed to zero rifles and shotguns without live fire. Simply chamber the boresight like a standard cartridge, and a visible laser dot projects onto your target, showing precisely where your rifle's bore is pointed. This method eliminates wasted ammunition during initial scope setup and accelerates the sighting-in process for any barrel configuration.

Measuring 5.35 inches in length and weighing just 0.26 lbs, the boresight fits standard 7mm rifle chambers. The laser alignment system allows operators to confirm scope tracking and reticle alignment indoors or at close range before committing to range time or tactical training. This approach conserves ammunition costs and reduces setup time—critical factors for competitive shooters, hunters transitioning between rifles, and law enforcement units managing multiple firearms platforms.

Boresighting is a preliminary step that must be followed by live-fire confirmation at distance to account for ballistic variables such as bullet drop, wind drift, and ammunition-specific velocity variations. The Sightmark boresight removes mechanical guesswork from the initial setup phase, enabling shooters to place rounds on paper faster and fine-tune zero more efficiently. It works across all 7mm rifle platforms—bolt-action, semi-automatic, or lever-action designs—making it a versatile addition to any rifle owner's tool kit.
