Aim Sports PJBS308 Laser Bore Sight .243/.308/7mm-08 Red Laser

The Aim Sports PJBS308 Laser Bore Sight eliminates guesswork when zeroing rifles chambered in .243 Winchester, .308 Winchester, and 7mm-08 Remington. This precision tool projects a bright red laser dot that shows exactly where the barrel points, allowing shooters to get on paper quickly and save ammunition during the zeroing process.

What Makes This Different

Unlike generic bore sights that require multiple adapters or fit loosely, the PJBS308 features a machined brass construction that chambers directly into the rifle like a cartridge. The 635-655 nanometer wavelength produces a highly visible red dot that remains bright in various lighting conditions. This direct-chamber design provides superior alignment accuracy compared to magnetic or expandable bore sights that can shift during use.

Key Features

• Chambers directly in .243 Win, .308 Win, and 7mm-08 Rem without adapters
• Machined brass construction ensures consistent chamber fit and alignment
• 635-655 nM red laser wavelength for optimal visibility
• Class IIIA laser output safe for indoor and outdoor use
• Compact design fits completely within the chamber
• No batteries required - activated by firing pin contact
• Durable brass body withstands repeated chambering cycles

The PJBS308 proves invaluable for hunters mounting new scopes before season, competitive shooters switching between rifles, and anyone installing optics on precision rifles. The laser remains stable during bolt manipulation and provides consistent reference points at various distances. Range officers and shooting instructors find this tool essential for quickly diagnosing scope mounting issues and getting new shooters on target efficiently.
