Some range days start with a cold rifle, a new opticand the quiet hope that zeroing won’t eat the whole afternoon-or a small pile of ammo. That’s why we’ve been reaching for the MidTen Rechargeable Laser Bore Sight Kit,a universal,Class IIIA boresighter that promises accuracy,portability,and no more scrambling for coin cells. We’ve spent time unboxing it, fitting its adapters to a handful of common calibersand hauling the case to the bench to see whether the green laser’s 30-300 yard visibility claims hold up in real life.
On paper, it checks a lot of boxes: 32 numbered adapters covering everything from .17 to 12 gauge,clear instructions with easy-to-match serials,and a factory laser-centering process paired with an arbor that’s meant to keep things stable-especially on larger bore sizes. In practice,we appreciated how quickly we could swap calibers without guesswork and how the rechargeable design spared us mid-session battery juggling; a two-hour charge for up to 17 hours of runtime is a welcome change.
In this review,we’ll walk through build quality,setup,visibility indoors and out,and how closely it got us on paper before fine-tuning with live fire. We’ll also touch on where it excels,where it doesn’t,and who will benefit most-always with safe handling and range rules front and center.
our Overview and What We Found in the Case
From the moment we powered it up,we noticed a focus on precision and practicality. Factory laser-centering detection pays off with steady alignmentand the included arbor keeps things stable even in larger calibers. The green class IIIA laser (<5mW) stood out at dusk and indoors alike, remaining visible at roughly 30-300 yards. Equally compelling is the rechargeable design-about 2 hours on the cable delivered close to 17 hours of continuous runtime in our checks, which spares us from juggling button batteries. Rounding it out, the universal fit from .17 to 12GA and the organized labeling system made caliber changes refreshingly straightforward.
opening the hard storage case, we found a tidy, range-ready layout with clear directions and numbered adapters that match calibers at a glance. Everything has a slot, nothing rattlesand the setup feels geared toward swift, repeatable boresighting rather than fiddling.In short,it’s a kit built for getting on paper fast,traveling light,and keeping our routine efficient without sacrificing confidence in alignment.

Recommendations for Buyers Caliber Compatibility Battery Care and Best Practices
We recommend confirming caliber fit before your range day: the 32 numbered adapters cover everything from .17 to 12GAand the clear numbering makes selection quick-choose the sleeve that seats flush and tighten just enough for a wobble‑free hold. The stabilizing arbor shines on large bores, complementing the factory laser-centering checks for reliable alignment. Outdoors, the bright green beam is easier for our eyes to catch across its 30-300 yard visibility range while staying within safe Class IIIA limits (<5 mW). If you're new to boresighting, start at a shorter distance to get on paper, then stretch out once your reticle and impact are speaking the same language.
| Coverage | .17-12GA (32 adapters) |
| Visibility | 30-300 yd (green beam) |
| Laser Class | Class IIIA, <5 mW |
| Charge/Run | ~2 h charge ≈ up to 17 h use |
| Portability | Compact carry case |
- Fit check: Pick the smallest sleeve that seats flush; there should be zero wobble but no forced torque.
- Stability first: Use the arbor on large bores to keep the beam centered during installation.
- Start smart: Begin at 15-25 yards on a high‑contrast grid; refine at longer distances after your first alignment.
- track your setup: Note the adapter’s serial number for each firearm so repeat setups are instant.
The rechargeable design cuts battery fuss, but a little care goes a long way. We top up before heading out (a full charge takes about two hours), avoid deep dischargesand power off between strings to preserve runtime. Heat and cold sap performance, so don’t store it on a hot dashboard or in freezing temps.Keep the adapter threads cleanand wipe contacts to maintain consistent output. Above all, follow safe handling: verify the chamber is empty, open the actionand never direct the beam toward people or reflective surfaces at eye level.
- Charge routine: Pre‑charge, then bring a USB power bank for long sessions.
- Thermal care: Let the unit cool between extended use; extreme temps reduce brightness and life.
- Power discipline: Use brief on/off cycles while adjusting turrets to save hours of runtime.
- Maintenance: Lightly snug, never overtighten; store each sleeve back in its labeled slot.

How we read between the lines
- If reviewers mention “on paper in minutes,” we translate that as reliable alignment for 10-25 yards before live-fire fine-tuning.
- notes about daylight washout are normal for red lasers; indoor use or shaded conditions are where these tools excel.
- Comments about “wobble” or “drift when rotated” flag possible tolerance or collimation issues-common with any cartridge-style bore sighter.
- Mentions of “no more button batteries” are a meaningful quality-of-life win; charging habits matter more than raw runtime.
- Durability complaints tend to cluster around the tail switch and charging port-parts we treat gently and test early within return windows.

Q&A
Q: What exactly is the MidTen Rechargeable Laser Bore Sight, and who is it for?
A: It’s a universal, rechargeable laser boresighter designed to get optics and irons roughly aligned before live-fire zeroing. We see it as a time- and ammo-saver for hunters, target shootersand anyone mounting new optics on rifles, shotgunsor pistols.
Q: Which calibers does it cover?
A: The kit includes 32 numbered adapters covering .17 caliber through 12 gauge. That spans common options like .22 LR, 9mm,.223/5.56, .308/7.62and 12 GA, among many others.
Q: Does it work with both rifles and handguns (and shotguns)?
A: Yes. If your barrel accepts an adapter size from .17 to 12 GA, you’re covered. We’ve used it on bolt guns, AR-pattern rifles, semiauto pistolsand pump shotguns without drama.
Q: Red vs. green laser-what should we choose?
A: MidTen offers both.We favor green for visibility; it’s easier for our eyes to pick up in varied lighting. The unit we tested was green (Class IIIA,<5 mW).Q: How visible is the laser in real use?
A: MidTen rates visibility from 30 to 300 yards. In our experience, green stands out indoors and in shade; under bright, midday sun, expect visibility to drop. A shaded target or lower-light hours help.
Q: How accurate is it? Can we skip live-fire zeroing?
A: It's for getting “on paper.” Factory laser-centering and the stabilizing arbor help, but you still need to confirm and fine-tune with live ammo. Think alignment tool, not a final zero.
Q: How do we pick and install the right adapter?
A: Match your caliber to the adapter's serial number using the included guide, choose the snug fitand seat it gently-snug, not forced.The arbor helps keep everything centered, especially on larger bores.
Q: Will the adapters or arbor scratch our barrel or crown?
A: Used correctly and kept clean, they shouldn't. We always wipe the adapter and muzzle before use and avoid overtightening. If something feels gritty or too tight, stop and recheck sizing.
Q: How stable is it in big-bore barrels?
A: The included arbor is there to add stability in larger calibers and shotguns. We found it mitigates wobble so the dot doesn't dance with minor handling.
Q: How long does the battery lastand how do we charge it?
A: It's rechargeable and rated up to about 17 hours of continuous runtime after roughly a 2-hour charge. A charging cable is included, so no coin cells to chase.
Q: What's in the box?
A: The laser unit, 32 numbered adapters, the stabilizing arbor, a charging cable, user instructionsand a hard storage case that's easy to toss in a range bag.
Q: Is the laser safe?
A: It's a Class IIIA laser (<5 mW). As always, don't stare into the beam, don't point at people, petsor aircraftand follow all local laws. Treat the firearm as if it's loaded, verify it's unloadedand keep it pointed in a safe direction while boresighting.
Q: Any setup tips that helped us?
A: We level the rifle, aim at a high-contrast targetand make coarse windage/elevation adjustments on the optic until the reticle and laser coincide at our chosen reference distance. Then we confirm at the range with live fire.
Q: What zero distance should we use with the laser?
A: Use whatever zero scheme you normally prefer (such as, a common rifle zero at 50/100 yards). The boresight just gets you close at that chosen distance.
Q: Can we use it through a muzzle device or suppressor?
A: Install it directly in the barrel per the manual. We remove suppressors and avoid inserting through devices that could interfere with adapter alignment.
Q: How portable is the kit?
A: Everything lives in a compact, protective case. We've found it toss-and-go convenient for range days or field adjustments.Q: Any limitations or gotchas?
A: Extremely bright sun can wash out the dot; worn or out-of-spec muzzles may fit looser; and it's not a replacement for live-fire zeroing. Also, stick to the correct adapter-forcing the wrong size is asking for trouble.
Q: What about warranty or support?
A: Policies can vary by seller and region. We recommend checking MidTen's current warranty terms and the retailer's return window before purchase.
