Bushnell Magnetic Boresighter

The Bushnell Magnetic Boresighter is a universal bore-sighting tool engineered to accelerate rifle zeroing across all calibers and firearm platforms without requiring caliber-specific adapters. The magnetic design eliminates the need for arbor swaps, allowing operators to seat the boresighter securely in the bore regardless of caliber—a significant time-saver on the range or during weapons qualification cycles. This approach reduces setup friction when zeroing everything from .223 Remington carbines to large-bore rifle systems.

The unit weighs just 0.31 lbs and measures 5.75 x 2 x 8.75 inches, making it compact enough to pack in a range bag or armor plate carrier without adding meaningful weight or bulk. Its light footprint doesn't compromise functionality—the magnetic grip is strong enough to hold position during the zeroing process while remaining simple to remove and reposition. This bore-sighting method projects a laser bore axis reference, allowing shooters to align their optic to the barrel's true center without firing rounds, which conserves ammunition and accelerates the zeroing workflow on a busy range or in a training environment.

This tool is essential for armorer operations, law enforcement firearms instructors, military range personnel, and serious sport shooters who need to zero multiple rifles or calibers efficiently. Whether you're running a qualification cycle, field-testing new optics, or servicing returned weapons, the magnetic boresighter eliminates the guesswork and the frustration of managing multiple caliber-specific tools. Bushnell boresighters are recognized in the industry for straightforward function and durable construction, making this model a dependable addition to any firearms maintenance kit.
