Sightmark SM39017 .45 ACP Red Laser Boresight with Battery & Case

The Sightmark SM39017 delivers precision bore sighting for .45 ACP firearms, eliminating guesswork when zeroing optics or iron sights. This brass-constructed laser boresight projects a red dot that aligns with your barrel's bore axis, allowing shooters to establish initial zero before firing a single round.

What Makes This Different

Unlike generic plastic boresights that can shift during use, the SM39017 features machined brass construction that maintains consistent chamber fit. The red laser operates at 635-650nm wavelength for excellent visibility in most lighting conditions. Where cheaper alternatives require constant battery changes, this unit includes a dedicated battery pack that extends operational time significantly.

Key Features

• Machined brass construction ensures precise chamber fit in .45 ACP firearms
• Class IIIA red laser (635-650nm) visible up to 100 yards in optimal conditions
• Included battery pack extends runtime beyond standard coin cell designs
• Protective carrying case prevents damage during transport and storage
• Works with all .45 ACP chambered pistols and carbines
• No gunsmithing or modification required for installation
• Instant activation when chambered - no external switches to operate

Range time becomes more efficient when initial sight alignment happens at home rather than the firing line. Competition shooters use boresights to verify zero before matches, while hunters rely on them for quick scope checks after travel. The brass construction withstands repeated chambering cycles without dimensional changes that affect accuracy. Indoor ranges particularly benefit from this tool since it eliminates the need for live fire during initial setup.
