Aimshot AR264 Arbor - Multi-Caliber Bore Sight Tool

The Aimshot AR264 Arbor delivers precision bore sighting capabilities across multiple magnum calibers in one versatile tool. This professional-grade arbor system eliminates guesswork when mounting new optics, saving both time and ammunition at the range.

What Makes This Different

Unlike single-caliber bore sights that require multiple purchases, the AR264 arbor accommodates eight different magnum cartridges through its expandable design. The precision-machined construction ensures consistent alignment across all supported calibers, while the durable brass and steel components withstand repeated use without dimensional changes. This multi-caliber approach reduces the need for separate tools, making it ideal for gunsmiths and shooters with diverse rifle collections.

Key Features

• Compatible with 264 Win Mag, 300 Win Mag, 338 Win Mag, 308 Win, 358 Norma Mag
• Supports 257 Wby Mag, 300 Wby Mag, 340 Wby Mag weatherby cartridges
• Works with 7mm Remington Magnum and 7mm STW chamberings
• Precision-machined brass construction for dimensional stability
• Expandable arbor design fits multiple bore diameters securely
• Knurled adjustment mechanism for precise centering

Field testing shows consistent zero establishment within 2-3 shots when using this arbor system, compared to 8-10 rounds with traditional methods. The tool proves particularly valuable for hunters preparing multiple rifles before season, competitive shooters switching between different cartridges, and professional gunsmiths servicing various magnum calibers. Weather-resistant materials maintain accuracy even in humid conditions or temperature extremes.
