.308 CARTRIDGE RED LASER BORE SIGHTER

The NcSTAR .308 Cartridge Red Laser Bore Sighter is a compact, battery-powered alignment tool designed to quickly verify rifle zero without firing a round. This laser bore sighter inserts directly into the .308 chamber, projecting a visible red dot onto a target at distance, allowing shooters to confirm point-of-aim convergence with mounted optics and correct sight picture before live fire begins.

Bore sighting with a laser cartridge eliminates the need for initial ammo expenditure and time spent shooting up ammunition during preliminary zero work. The laser-based system works at indoor range distances or outdoor yards, giving operators immediate visual feedback on barrel-to-optic alignment. Weighing just 0.05 lbs and measuring 2.65 inches in length, the device fits standard .308 Winchester chambers without modification. The red laser wavelength remains visible in moderate ambient light, though low-light indoor shooting bays provide optimal visibility for precise alignment confirmation.

This tool serves tactical shooters, hunters, and precision rifle enthusiasts preparing rifles for duty, competition, or field use. It accelerates the sighting-in process for new scope mounts, barrel replacements, or optic changes. Military, law enforcement, and civilian marksmen use bore sighters as a baseline confirmation step before final live-fire validation. The .308 cartridge sizing ensures compatibility with AR-10 platforms, bolt-action rifles, and designated marksman rifles chambered in 7.62x51mm NATO and .308 Winchester.

NcSTAR's laser bore sighter represents a practical approach to rifle setup, eliminating guesswork during the alignment phase. While not a substitute for live-fire confirmation, it provides immediate, repeatable reference geometry that reduces wasted ammunition and confirms that scope mounting has been done correctly before ammunition costs and time are invested at the range.
