Sightmark SM39020 Red Laser Boresight .22-250 Rem 6.5 Creedmoor

The Sightmark SM39020 boresight eliminates guesswork when zeroing rifles chambered in .22-250 Remington and 6.5 Creedmoor. This precision laser boresight reduces ammunition costs and range time by providing an accurate starting point for scope adjustments before live fire testing.

What Makes This Different

Unlike basic boresights that require multiple caliber-specific units, the SM39020 accommodates two popular long-range cartridges with included brass casings. The red laser operates at 632-650nm wavelength for enhanced visibility in various lighting conditions. Professional gunsmiths and competitive shooters rely on Sightmark's consistent beam alignment and durable construction that withstands repeated chambering cycles.
