Overview
This .45 ACP laser boresight is designed to simplify initial sight-in work for pistols by projecting a visible aiming point before any live fire is used. It chambers like a standard round, making it a practical setup tool for hunters, competitive shooters, and law enforcement who want to align optics or sights efficiently at the range. Live fire can then be used for final adjustment, which helps account for real-world variables that a bore sight alone cannot address. It is a straightforward option for shooters who want a faster, less wasteful way to get on target.

Considerations & Trade-offs
- Designed for .45 ACP pistols only, so it is not a universal boresight for other chamberings.
- The laser is intended to get you close on paper; live fire is still needed to fine tune zero and account for distance-related bullet drop.
- Laser range is listed at 300 feet, but practical sight-in use will depend on lighting and how clearly the dot can be seen.
- Batteries are included, but the specifications list both AG3 and AG5 battery types, so replacement should be verified before purchase.
