BSA Boresighter with 15 Arbors and Hard Case

The BSA Boresighter with 15 Arbors and Hard Case is a professional-grade alignment tool designed to save ammunition and training time by allowing shooters to achieve precise zero without firing rounds downrange. Purpose-built for law enforcement, military personnel, and competitive shooters, this boresighter eliminates the inefficiency of traditional sight-in procedures where countless shots are wasted during initial bore alignment. The included hard case protects the precision optics during transport and storage, ensuring reliability in the field or at the range.

At its core, the BSA Boresighter functions by inserting caliber-specific arbors into the bore to optically align your scope or sight with the barrel's centerline. The system includes 15 arbor options—ranging from .177 through .50 caliber—covering everything from rimfire small-game rifles to heavy magnum hunting and tactical platforms. Each arbor is precision-engineered to match bore diameter, and the laser-collimated design projects a beam that reflects off the target to show exact alignment. The durable hard case keeps all arbors organized and accessible, reducing setup time and preventing loss or damage during deployment.

Tactical operators, armorer shops, and shooters with multi-caliber arsenals benefit most from this comprehensive system because one tool handles the entire spectrum of common rifle and handgun bores. Field zeroing becomes faster and more accurate—critical for personnel who must transition between duty rifles, backup weapons, or training platforms. The portability and durability make it ideal for mobile armorer work, pre-deployment checks, or maintaining fleet weapons. Compatibility spans standard hunting rifles, AR-platform builds, precision bolt-actions, and large-bore hunting cartridges, making this an essential addition to any serious shooter's toolkit.
