Aimshot MBSKIT1 Modular Boresighter Kit 223/243/30-06 Brass

The Aimshot MBSKIT1 Modular Rifle Boresighter delivers precision scope alignment for multiple calibers without firing a single round. This brass construction system eliminates the guesswork and ammunition waste associated with traditional zeroing methods. Hunters and competitive shooters save both time and money while achieving consistent accuracy across different rifle platforms.

What Makes This Different

Unlike single-caliber boresighters, the MBSKIT1 features interchangeable arbors that accommodate .223 Remington, .243 Winchester, and .30-06 Springfield cartridges. The modular design means one tool handles multiple rifles in your collection. Precision-machined brass construction maintains dimensional stability and provides repeatable results shot after shot. The system delivers alignment accuracy within 1 inch at 100 yards before live fire confirmation.

Key Features

• Modular arbor system fits .223 Rem, .243 Win, and .30-06 Springfield chambers
• Precision-machined brass construction for dimensional accuracy and longevity
• Laser diode projects bright red dot visible at 100+ yards in daylight conditions
• Self-centering design ensures consistent chamber alignment across different rifles

Field testing demonstrates reliable performance across temperature ranges from -10°F to 120°F. The laser remains stable during transport and maintains zero reference point between uses. Competition shooters report 75% reduction in zeroing ammunition requirements when switching between rifles. The system proves equally effective for hunting rifle preparation and tactical applications where ammunition conservation matters.
