MidTen Laser Bore Sight Kit for.223/9mm/.40/.45/243/308 - Accurate

In this review the MidTen Laser Bore Sight Kit is judged on ease of use and practical value for routine rifles and pistols. It targets shooters who need a quick way to align sights or scopes without firing a round, and its single biggest selling point is convenience: three chamber-sized boresighters in a small tin with plenty of spare batteries make it ready for field or bench use. For someone who wants a simple, low-effort method to get on paper before final live-fire adjustments, this kit delivers that baseline performance reliably.

Key Features

• Common caliber set: Includes dedicated bore lasers for 9mm,.40 cal and.45 ACP so users can match the approximate chamber size on many common handguns quickly and without adapters.
• Plenty of batteries: The kit ships with 12 LR41 batteries so each boresighter is ready to run multiple sessions and the 45 ACP unit, which uses three cells, lasts up to about 1.5 hours.
• High accuracy from factory: The lasers are reported accurate out of the box and make it easy to line up iron sights or initial scope adjustments before firing live rounds.
• Sturdy brass construction: Machined brass bodies resist temperature changes and provide a durable, chamber-sized feel when seated into the bore.
• Compact storage: The set comes packed in a small tin case for neat storage and simple transport to the range.

Who It's For

This kit is best for recreational shooters, hunters and hobbyists who work with common pistol calibers and want a quick, no-friction method to get sights or scopes close to center before live-fire zeroing. It is particularly handy for those who move between several pistols and appreciate a simple, caliber-specific plug rather than a universal adapter.

Shooters seeking sub-MOA precision tools for long-range rifles or users who require a single tool to fit many uncommon calibers should look elsewhere; the set covers common handgun sizes and is not a substitute for a precision chronograph or professional boresighting service for specialized rifles.

Pros & Cons

Pros

• Compact kit that covers common pistol calibers and stores neatly in a tin case.
• Includes ample LR41 batteries so users can start sighting immediately without extra purchases.
• Brass construction gives a solid, durable feel and resists heat better than plastic plugs.
• Simple to use and bright enough for quick alignment on a target at typical zeroing distances.

Cons

• Functionality and perceived accuracy are mixed among users, so some may find inconsistent results depending on individual firearms.
• Designed for common calibers only, so it will not fit less common rifle chambers without adapters.

Our Verdict

The MidTen Laser Bore Sight Kit is a practical, budget-friendly option for pistol owners who want a fast way to get on paper before live-fire zeroing. It is good value for shooters who use common calibers and appreciate the brass feel and included batteries, though those needing absolute consistency across a broad range of firearms should test fit before relying on it as their sole boresighting method.
