Aimshot MBSKIT3 Modular Rifle Boresighter Kit 243/308/7.62x54mm

The Aimshot MBSKIT3 Modular Rifle Boresighter Kit eliminates guesswork when zeroing scopes and iron sights across multiple calibers. This chamber-inserted boresighting system projects a laser dot downrange, allowing shooters to align optics before firing expensive ammunition.

What Makes This Different

Unlike traditional bore sighters that require different units for each caliber, this modular kit includes interchangeable brass chamber inserts for 243 Winchester, 308 Winchester, and 7.62x54mm Russian cartridges. The precision-machined brass construction ensures consistent alignment with the rifle's bore centerline. Battery-powered laser operation provides clear visibility at distances up to 100 yards in typical indoor lighting conditions.

Key Features

• Three caliber-specific brass chamber inserts: 243 Win, 308 Win, 7.62x54mm
• Red laser diode with adjustable focus for precise dot projection
• Precision-machined brass construction matches chamber dimensions exactly
• Battery-powered operation eliminates need for external power sources
• Compact storage case keeps all components organized
• Works with bolt-action, semi-automatic, and lever-action rifles
• Compatible with scoped and iron sight configurations

This boresighter reduces range time and ammunition costs by establishing initial zero before live fire testing. Hunters mounting new scopes can achieve preliminary alignment in their workshop or garage. Competition shooters switching between rifles benefit from quick scope transfers without extensive range sessions. The system works effectively in indoor environments where live fire testing isn't practical.
