Sitelite SL-150 Ultra Mag Boresighter

The Sitelite SL-150 Ultra Mag Boresighter is a precision aiming tool designed for shooters who demand fast, accurate zero confirmation without firing a round. Whether you're a law enforcement armorer, military gunsmith, or competitive rifleman, this boresighter streamlines the critical pre-range setup phase that separates tight groups from wasted ammunition.

The SL-150 addresses a fundamental operational need: establishing a reliable bore-to-optic relationship quickly, safely, and repeatably. It is capable of functioning across magnum and standard rifle calibers, delivering consistent laser alignment that eliminates parallax errors inherent to traditional iron-sight zeroing. The boresighter's compact profile makes it ideal for go-bag inclusion or permanent placement in an armory.

Professionals managing weapon systems across departments or units benefit most from the SL-150's efficiency and repeatability. Concept Development Corp.'s engineering ensures the laser delivers repeatable point-of-aim accuracy at common range distances, allowing shooters to confirm optic mounting torque, confirm bore concentricity, and validate sight picture before live fire.
