BUSHNELL BORESIGHTER MAGNETIC MULTICAL

Description

Getting a scope or red dot roughly zeroed before heading to the range used to mean burning through a box of ammunition just to get on paper. The Bushnell Magnetic Boresighter gives you a faster starting point by attaching directly to the muzzle via a strong magnet rather than requiring a set of caliber-specific arbors. That magnetic attachment is the key practical advantage: one tool works across rifles, handguns, and shotguns regardless of bore diameter, so there is no fumbling through a case of inserts or discovering you left the right arbor at home.

The boresighter projects a reference grid that you align with your optic while the firearm is stationary. Once the reticle or dot is centered on the grid, you have a mechanical starting point that puts your first shots close enough to fine-tune from the bench rather than hunting for them on the berm. It is a time-saver and an ammunition-saver, not a substitute for live-fire confirmation — the final zero still has to be established by shooting, because the boresighter cannot account for barrel harmonics, ammunition point of impact, or parallax.

Construction is metal throughout, which keeps the tool durable and the magnet seated firmly against the crown without shifting during use. The device is manual rather than laser-based, meaning there is no battery to go dead in a cold blind or a gear bag at the bottom of a truck. Bushnell describes it as a precision instrument built for long-term service, and the all-metal body supports that intent. At a modest price point, it is a straightforward addition to any cleaning kit or range bag for anyone who regularly mounts new optics or moves scopes between rifles.
