Zeroing day usually means a pile of ammo, a sore shoulder, and plenty of guesswork. This time, we brought the MidTen Bore Sight Laser, 32 Adapters Professional Red/Green Laser Bore Sight kit, and our routine changed the moment we snapped the first adapter into place. The kit arrives in a compact storage case with 32 clearly marked adapters covering everything from .17 to 12 gauge. The first four use striped markings, the rest are numbered-simple touches that actually speed things up at the bench. the aircraft-grade aluminum body feels ready for field knocks, the soft-touch power button is easy to find with gloved hands, and the extra arbor for .551-12GA adds welcome stability on our shotguns.
We tested the green laser variant for most of our sessions and found it easier to pick up in bright conditions than red, helping us rough-in optics before firing a single round. Battery swaps are rapid, and the included CR2 cells kept us running through multiple rifles and a scattergun session without fuss.
In this review, we’ll walk through setup across common calibers, our accuracy checks before live fire, daylight visibility, battery life, and how the MidTen stacks up against other global bore sighters we’ve used. If you’re debating whether this kit can actually save you time and ammo,we’ve put it through the paces to find out.
Our hands on overview of the MidTen bore sight kit
From unboxing to first zero,we were impressed by the build and polish.The body feels stout thanks to its aircraft‑grade aluminum and shockproof construction, and the portable storage case keeps the many parts tidy in the field.The soft, sensitive button switch makes on/off quick without fumbling. Most helpful, the kit’s 32 adapters are all clearly identified-adapters #1-#4 use stripes to denote size, while #5-#32 are numbered with Arabic numerals-so finding the right fit from .17 through 12GA is fast. The included additional arbor for .551-12GA (adapters #20-#32) expands the rear end for a firmer muzzle hold, wich noticeably improved stability on larger bores.
- 32 clearly marked adapters: stripes (#1-#4) and numerals (#5-#32)
- green Class IIIA laser (<5mW): visible from 30-300 yards
- Extra arbor for large calibers: tighter, steadier fit
- Premium aluminum alloy: rugged, portable, range-ready
- Quick, tactile switch: simple, precise control
On the bench, the bright green beam stayed crisp in varied light, helping us rough-in optics quickly and cut down on ammo spent chasing zero. Power is handled by two upgraded CR2 batteries, each offering up to 8 hours of runtime, and they swap in seconds-even in cold weather. Between the robust construction and the intuitive adapter system,dialing in across multiple platforms felt seamless,whether prepping for a hunt or tidying up a new build before fine-tuning at the range.

Features that stood out build quality adapters and laser clarity
build quality is the first thing that impressed us: the aircraft‑grade aluminum body feels robust yet lightweight, and the shockproof design inspires confidence when we’re moving between the bench and the field. The adapter system is equally thoughtful. We get 32 clearly marked adapters, with #1-#4 identified by stripes and #5-#32 by Arabic numerals, so matching calibers is quick and foolproof. The standout detail is the additional arbor for .551-12GA, which expands the rear diameter for a steadier muzzle fit-exactly what we want for repeatable alignment across everything from .17 to 12GA.
- Premium alloy + shockproof: built for dust, moisture, and the occasional bump.
- Numbered adapters: fast caliber selection without guesswork.
- stability booster: added arbor keeps large bores snug and true.
- Portable case: organized storage that’s range‑bag ready.
on clarity, the green Class IIIA laser (<5 mW) punches through bright conditions with a dot we can track from 30-300 yards. It’s crisp in midday sun and steady in low light, letting us confirm alignment without burning through ammo. Power is handled by two upgraded CR2 batteries delivering an 8‑hour runtime each,swapping in seconds-even in the cold. The sensitive button switch makes on/off effortless with gloved hands, rounding out a setup that’s precise, practical, and time‑saving.
| Feature | What we noticed | Why it matters |
|---|---|---|
| Laser color | Bright green, daylight‑visible | Faster daytime zero checks |
| Visibility | 30-300 yd clear dot | Indoor to long‑bay versatility |
| Power | 2× CR2, ~8 h each | Fewer swaps, longer sessions |
| Fit system | 32 numbered adapters + arbor | Snug, wobble‑free alignment |
| Construction | Aircraft‑grade, shockproof | Field‑ready durability |
Setup experience and zeroing performance at the range
Getting this kit dialed in was refreshingly straightforward. The adapters are clearly marked-stripes for #1-#4 and Arabic numerals for #5-#32-so we matched calibers quickly from .17 up to 12GA without guesswork. The additional arbor for .551-12GA (pairs with #20-#32) locked the unit steadier at the muzzle than most universal options we’ve tried, and the soft, sensitive button made on/off toggles easy even with gloves. Build quality stands out; the aircraft‑grade aluminum feels purpose-built for field abuse, and swapping the included CR2 batteries took seconds.With 8 hours per battery, we never felt rushed during a long bench session.
- Portable case: Keeps adapters organized and protected.
- Fast ID system: Numbered/striped adapters reduce setup time.
- Stability boost: Added arbor improves muzzle fit on larger bores.
- cold‑weather friendly: Batteries held up in freezing temps.
At the range, the bright green Class IIIA laser stayed easy to see from 30 to 300 yards, even under harsh midday sun, which sped up initial alignment. We started close, confirmed windage/elevation, then stretched out; the combination of a crisp dot and shockproof construction meant our point of aim stayed consistent between groups. Net result: fewer shots burned getting on paper and quicker refinement to a precise zero, especially across different platforms using the same kit.

Our recommendations and tips to get the most from this kit
Dial in setup before the range: pick the correct adapter by its engraving-#1-#4 use stripes, #5-#32 use Arabic numerals-and seat it snugly so there’s no wobble. For larger bores (.551-12GA using #20-#32), slip on the additional arbor to steady the muzzle fit. Start boresighting at 25-36 yards to get “on paper,” then confirm at your preferred zero distance with live fire. The bright class IIIA green laser is easy to spot from roughly 30-300 yards; in intense sunlight, aim at a shaded or reflective target to speed alignment. Use the sensitive button switch to pulse the beam-on for adjustments,off between steps-to save battery and avoid mirage near the muzzle.
- Use the engravings: stripes for #1-#4, numerals for #5-#32-no guesswork.
- Stabilize big bores with the included arbor on #20-#32 adapters.
- Start close (25-36 yds), then confirm zero at distance with a few shots.
- Beat bright sun by shading the target or using a reflective bull.
- Tap, don’t drain: quick presses of the soft switch between adjustments.
| Action | Do this | Why it helps |
|---|---|---|
| Pick adapter | Read the engraving (stripes #1-#4, numerals #5-#32) | Fast, correct fit |
| Stabilize muzzle | Add arbor for #20-#32 (.551-12GA) | less wobble, truer aim |
| First zero | boresight at 25-36 yards | On paper, fewer rounds |
| Daylight clarity | Shade target / reflective bull | Faster alignment |
| Max runtime | Rotate the two CR2s (≈8 hrs each) | All-day sessions |
| Protect optics | Store in case, wipe lens and threads | Consistent accuracy |
keep it running smoothly: the aircraft-grade aluminum body shrugs off field bumps, but we still wipe the lens and adapter threads after dusty sessions and park it in the portable case between rifles. The two upgraded CR2 batteries deliver around 8 hours per cell, even in cold weather; we carry the spare in a warm pocket and swap in seconds. Label adapters by firearm to speed repeat setups, and avoid overtightening-just a firm, even seat is enough. treat the beam like any laser: never point at people or aircraft, and always verify with live fire. Done right,this kit trims time and ammo while getting us confidently on target.

| Build & case | Metal housing; organized storage | Misplaced adapters; foam cutouts loosening | Inventory adapters after each session; label your most-used sizes |
| Ease of use | Fast setup; clear on/off | Vague instructions; tiny screws/adapters | Lay out parts on a light towel; follow a step-by-step routine |
| Caliber coverage | From .17 to 12GA in one kit | Edge cases (odd wildcats, tight bores) | Coverage looks strong; verify fit on less-common chambers |
| Value & support | Cost-effective versus caliber-specific units | Warranty hoops; slow responses | Check seller warranty terms and response time pre-purchase |
Signals we’d scan for in real-world reviews
- Concentricity test results: Do users report the dot staying put when the bore sighter is gently rotated in the chamber?
- Adapter sizing notes: Any specific calibers called out as to loose or too tight?
- Visibility anecdotes: Green dot usability at midday; red dot clarity on indoor ranges at 25 yards.
- Battery specifics: Brand/type shipped, runtime per session, and whether replacements improved performance.
- Case and organization: Are adapters clearly labeled and secure after repeated use?
- Longevity: Any drift, switch failures, or laser dimming after several zeroing sessions.
- Manufacturer response: Turnaround time and helpfulness when parts or adapters arrive out of spec.
Interpreting likely pros and cons
| Likely Pros | Likely Cons |
|---|---|
| Huge caliber coverage in one box | Button-cell dependence and short duty cycles |
| Green option for daylight zeroing | Potential adapter variance between barrels |
| Speeds up initial zero and mount checks | Not a substitute for live-fire confirmation |
Review-reading checklist (quick skim)
- look for at least one multi-platform user (e.g., .223, .308, 12GA) confirming fit across adapters.
- Find photos of the dot at known distances (10-25 yards indoors; 25-50 yards outdoors).
- Seek comments on rotation tests and group size before/after live fire.
- Note any fixes: Teflon tape on stems, adapter order, or battery brand swaps.
- Confirm warranty handling for misaligned lasers or missing adapters.
Bottom line: We expect most buyers to value the MidTen kit for fast, multi-caliber setup-especially with the green laser outdoors-while critical reviews will likely focus on adapter concentricity, daylight visibility for red, and battery stamina. As real customer data rolls in, we’ll refine this picture with concrete numbers and quotes.
Pros & cons
Pros & Cons
After dialing in with MidTen’s 32-adapter laser bore sight,here’s where it shined-and where we wanted a bit more.
| Pros | Cons |
|---|---|
| Broad caliber coverage (.17 to 12GA) | Learning curve with 32 adapters |
| Bright green laser visible 30-300 yds | CR2 batteries aren’t as common as AA/AAA |
| Numbered,well-made adapters + extra arbor | No stated waterproof/IP rating |
| Rugged aluminum build; shock-resistant | Requires careful centering for best precision |
| Long 8-hour runtime per battery | Still needs live-fire confirmation of zero |
What we liked
- Universal fit with 32 adapters covers everything from varmint rigs to 12-gauge,making one kit serve most of our safe.
- Green Class IIIA laser is easy to pick up from 30 to 300 yards, especially in bright daytime where red often fades.
- Adapters are clearly numbered (stripes on #1-#4, numerals on #5-#32), which sped up our selection and reduced guesswork.
- Additional arbor for .551-12GA stabilizes the muzzle fit on larger bores; less wobble, more repeatability.
- Aircraft-grade aluminum and shockproof construction handled range bags, dust, and bumps without a hiccup.
- Soft,sensitive power button and a portable storage case make it quick to deploy and pack away.
- two included CR2 batteries with up to 8 hours each meant we didn’t sweat power during a full day of setup.
- Helps save time and ammo by getting us on paper fast before fine-tuning with live fire.
What gave us pause
- Adapter-heavy kits take practice; it’s easy to pick a near-fit that isn’t perfect-centering matters for repeatable results.
- CR2 cells work well but are pricier and less ubiquitous than AA/AAA; bring spares to avoid a mid-session scramble.
- No stated water/dust ingress rating; “field tough” is reassuring, but an IP spec would inspire more confidence in foul weather.
- Muzzle-end bore sighters can be sensitive to crown/adapter fit; even with a stable arbor, we still needed live-fire to finalize zero.
- Product listings mention both red and green options; confirm the variant you’re buying if you need daytime-bright visibility.
| Best for | Not Ideal For |
|---|---|
| Multi-caliber owners wanting one kit | Set-and-forget users who won’t confirm at the range |
| Daylight sight-ins needing a bright dot | Anyone without easy access to CR2 batteries |
| Hunters who value rugged, packable gear | users who prefer chamber-style bore sighters |
Safety note: As with any laser device, use responsibly and never direct the beam toward people, aircraft, or reflective surfaces.
Q&A
Q: What calibers does the MidTen kit cover?
A: It ships with 32 adapters that fit roughly .17 through 12 gauge. The included “additional arbor” stabilizes adapters #20-#32 for .551-12GA bores.
