Sighting in a new setup can be a quite drain on time and ammo, so we’re always on the lookout for tools that get us on paper faster and with fewer variables. That’s what led us to the MidTen Bore Sight Laser. We picked up the .45 ACP variant from a lineup that also covers 20-gauge and 7.62x54R, and took it through our usual pre-range routine to see if it lived up to the promise of quick, no-fuss zeroing.
Out of the box, the brass construction felt solid and purpose-built, and the cartridge slipped cleanly into our .45 Auto chamber with no wobble. The Class IIIA red laser (under 5mW) snapped on confidently, and the kit’s inclusion of two sets of LR41 batteries meant we weren’t juggling spares mid-session. Within minutes, we had a stable reference point for our sights, trimming the guesswork before ever touching live rounds.
We’re not expecting a boresighter to replace final adjustments on the range, but if it can reliably put us close and save a handful of cartridges, that’s a win in our book. In this review, we’ll break down our experience with build quality, ease of use, battery life, and-moast importantly-how accurately this MidTen unit gets us from benchtop to first-impact. As always, we started with a clear chamber and followed strict safety protocols before dropping the laser in; from there, it was all about seeing whether this small red dot could make a big difference.
Our overview after putting the MidTen bore sight laser to work
After dropping the cartridge-style unit into a .45 Auto chamber, it seated cleanly with no play and produced a crisp, luminous red point. The sturdy brass construction kept everything aligned, and the Class IIIA (<5mW) beam made initial alignment straightforward. Within minutes we matched irons and an optic to the dot and confirmed on paper, needing fewer live rounds than usual. Battery swaps where simple, and the inclusion of two sets of LR41 batteries kept us running through multiple sessions without dimming.
- Caliber-specific fit for .45 ACP chambers
- Fast zeroing that saves time and money
- Easy to seat and remove; solid,repeatable positioning
- Helps cut down on wasted cartridges during setup
| Setup time | ≈ 5 minutes to align sights |
| Ammo saved | Noticed fewer rounds needed to confirm zero |
| Dot visibility | Excellent indoors; usable at dusk |
| Build feel | solid brass,snug chamber fit |
In practise,this tool shines as a pre-zero aid: it gets us on paper fast so live-fire fine-tuning is minimal. The high accuracy of the beam relative to the bore kept adjustments predictable, and repeated chamberings didn’t loosen the fit. Between the durable body, reliable alignment, and generous battery supply, it proved to be a practical, budget-kind way to streamline sighting and keep range time focused on confirming rather than chasing zero.

Features build and fit we noticed in real use
in the hand, the brass body feels reassuringly sturdy, and in the chamber it seats with a snug, rattle-free fit that inspires confidence. Dropping it into a .45 ACP barrel was straightforward; once the slide closed,the red dot appeared promptly and stayed stable during minor handling. The class IIIA output (under 5mW) delivered a crisp, round point that made coarse alignment simple and quick, helping us get “on paper” without firing excess rounds. Across a few insert/remove cycles, we saw consistent point-of-aim repeatability-exactly what we want from a boresighter used at the bench or at home before range day.
- Build: Solid brass helps protect the chamber and resists dings.
- Fit: Caliber-specific for .45 ACP-no wobble, no fuss.
- Laser: Class IIIA, under 5mW, with a clean, visible dot indoors.
- Power: Two sets of batteries included (6x LR41 total) for longer sessions.
- Speed: Fast zeroing that saves time and cuts ammo waste.
Real use highlighted its practicality: insert, confirm the dot on target, dial sights to meet it, and you’re close enough that live-fire fine-tuning takes just a few shots. Battery life felt reliable in short, repeated sessions, and having a spare set in the case eliminated downtime. While any red laser can look faint in bright sun,we found the dot perfectly workable in typical indoor bays and shaded benches.The net result is simple: less time fiddling, more time validating your zero.
| Laser Class | IIIA, <5mW | Clean dot for fast alignment |
| Batteries | 2 sets (6x LR41) | Swap-and-go, fewer interruptions |
| Material | Brass | Snug fit, chamber-friendly |
| Setup | Drop-in | Quicker zero, less ammo spent |
Performance and alignment across varied calibers
Across its caliber-specific options, we found alignment to be reassuringly consistent. The Class IIIA (<5mW) red dot is crisp enough for indoor benches and shaded ranges, and the sturdy brass build helps the cartridge sit concentrically, minimizing wobble as we dial turrets or nudge sights. In the .45 ACP chamber, it seated with a confident click; the 20-gauge and 7.62x54R counterparts mirrored that snug, centered feel, making initial windage and elevation tweaks quick and predictable.Accuracy is the standout here-precise indexing translates into fewer trial shots and less second-guessing before live fire.
- Caliber-specific bodies that sit perfectly in the bore for true-to-chamber alignment
- Fast zeroing that saves both time and ammunition
- Two sets of LR41 batteries included for extended sessions
- Clean, visible red dot for confident pre-zero checks
- Brass housing built to resist nicks and maintain concentricity
| Caliber | Fit & Setup | Suggested Start | Alignment impression |
|---|---|---|---|
| .45 ACP | Seats flush; simple battery install | 10-15 yd | Fast reference for handgun sight tweaks |
| 20-Gauge | Caliber-specific hull fit | 15 yd | Easy co-witness with bead or mounted optic |
| 7.62x54R | solid chamber lock-up | 25 yd | Stable dot for fine turret adjustments |
What ties these experiences together is efficiency: high accuracy that helps us conserve cartridges and shells while getting on paper fast. Whether we’re checking pistol irons, a shotgun bead, or a scoped rifle, the consistent point of reference made our zeroing workflow smoother-and the included extra batteries kept us working without interruption.

Q&A
Q: What exactly is the MidTen Bore Sight Laser and who is it for?
A: It’s a caliber-specific,cartridge-style red laser designed to sit in your chamber and project a dot down the bore. We use it to align sights or optics quickly so we’re “on paper” before we ever fire a live round. It’s ideal for shooters who want to save time and ammo when setting up or checking an optic.
Q: Which calibers does this one cover?
A: MidTen offers this boresighter in several caliber-specific versions. The .45 ACP unit fits.45 Auto chambers only, while the 20-gauge and 7.62x54R options are separate, dedicated versions. We always match the exact chambering-no substitutions across calibers.
Q: How accurate is it in practice?
A: For its intended job-getting us very close before live-fire-it’s impressively precise. It consistently puts us near point-of-impact so final zeroing takes fewer rounds. As with all bore sights, final verification and fine-tuning should be done safely at the range with live ammo.
Q: Does it really save time and money?
A: In our experience, yes. starting close to zero means fewer adjustments and fewer rounds spent getting dialed. It’s essentially a head start for your optic.
Q: Is the laser safe and legal to use?
A: It’s a Class IIIA red laser rated under 5mW, which is the typical consumer-safe class in many regions. We still treat it with care: never look into the beam, never point it at people, pets, vehicles, or aircraft, and always follow local laws and range rules.
Q: How visible is the red dot indoors and outdoors?
A: Indoors and in low light, the red dot is easy to see. In bright daylight, red is inherently harder to pick up than green. We plan our use accordingly or shade the target area when possible.
Q: Will the brass body scratch our chamber?
A: Brass is softer than most firearm steels, which helps. We keep both the chamber and boresighter clean, check for debris or burrs, and insert/remove it gently. Used properly, it’s been kind to our chambers.
Q: What batteries does it use and how long do they last?
A: It uses LR41 button cells and comes with two sets (six total). Runtime depends on temperature and on/off habits, so we carry spares and remove the batteries for storage to preserve life.
Q: How easy is it to set up?
A: Very. We confirm the firearm is fully unloaded, follow the manufacturer’s directions, and seat the unit in the matching chamber. From there, we align our sights/optic to the dot and confirm at the range with live fire.
Q: Can we use the .45 ACP version in .45 Colt or .45 GAP?
A: No. Each version is caliber-specific to the chamber dimensions. We only use the exact match-.45 ACP for.45 Auto, .45 Colt for .45 Colt, etc.
Q: Does it replace live-fire zeroing?
A: No. It’s a shortcut to get us close. We always finalize zero with live rounds at a safe range, per the optic manufacturer’s guidance.Q: How durable is it?
A: The brass construction feels sturdy and resists casual knocks in a range bag. As with any precision tool, we avoid drops, keep the laser lens clean, and store it dry.
Q: Any maintenance tips?
A: – Wipe the lens with a soft, lint-free cloth.
– Keep the chamber and the unit free of grit.
– Remove batteries between uses to prevent drain or corrosion.- Store it in a protective pouch to avoid dings.Q: Will it work with shotguns and rifles too?
A: Yes-if you buy the correct caliber/gauge version (such as, the 20-gauge model for a 20-gauge shotgun, or the 7.62x54R model for rifles in that chambering). We match the unit to the chamber, not the bore diameter alone.
Q: Anything we wish were different?
A: A brighter green option would help in harsh daylight, and a dedicated storage case would be a nice add. But for quick, precise pre-zero alignment, this red, brass-bodied unit gets the job done.
Achieve New Heights
Wrapping up, midten’s Bore Sight Laser lives up to the promise in our title: quick, precise zero without the fuss. The sturdy brass body and caliber-specific fit made it an easy drop-in for us, the Class IIIA (<5mW) red dot was consistent, and two sets of LR41 batteries kept us running without a scavenger hunt.
