If you’ve ever burned daylight (and ammo) chasing a fresh zero, you know the value of a bore sighter that just works. We brought the EZshoot Bore sight Kit out to the bench because it promises a one-tool solution for everything from .17 up to 12-gauge, with a push-button red laser and a pile of adapters that actually cover the calibers we shoot most. Out of the box, the pitch is simple: pre-calibrated at the factory, drop in the LR44 batteries, pick the right adapter, and get on paper quickly.
What stood out to us first was the breadth and association. Sixteen adapters, each clearly numbered, meant we weren’t squinting or guessing, and the specially designed arbor for .54-12GA gave a surprisingly snug, centered fit in our shotguns-stability we don’t always see in multi-caliber kits. The Class IIIA red laser (under 5mW) was bright enough to see in typical indoor setups and shaded outdoor corners, and the tactile push-button made it easy to cycle the beam without nudging our setup.
Battery swaps are usually the weak link with compact bore sighters, but EZshoot includes two full sets of improved LR44s-each set rated for about 2.5 hours-and the installation is straightforward once you follow the tilt-and-seat routine for the battery tray. On paper, it’s a range bag multitool; in practice, it aims to remove the friction between mounting glass and making that first clean confirmation shot. In the sections that follow, we’ll break down how well it holds zero across calibers, real-world brightness, and where the kit shines-and where it doesn’t.
Our hands on overview and what we noticed out of the box
Right out of the clamshell, we noticed a tidy, purpose-built kit: adapters are neatly organized and clearly numbered for speedy matching across .17-12GA calibers, while a specially designed arbor (.54-12GA) adds welcome stability in larger bores. The red Class IIIA laser (<5mW) came factory-calibrated,so our first switch-on had us on paper right away-no fiddling needed. The push-button switch feels responsive, and the inclusion of two sets of upgraded LR44 batteries (each set rated for up to 2.5 hours) is a smart touch for range days.
- factory-calibrated red laser for quick zero references
- 16 adapters covering .17-12GA, each with engraved numbers
- Arbor support for .54-12GA barrels improves alignment
- Button switch for clean on/off control
- Two LR44 sets included; up to 2.5 hours per set
| In the Box | Our Takeaway |
|---|---|
| Main unit | Pre-calibrated; laser was centered out of the gate |
| 16 adapters | Fast matching thanks to visible serial numbers |
| Arbor (.54-12GA) | Added rigidity for shotgun bores |
| 2 battery sets (LR44) | Swap-ready power for extended sessions |
| Battery tray | Tilt-and-slide insert; rotate cap to secure |
Setup was straightforward: we inserted three LR44 batteries, seated the tray with a gentle tilt-and-push, then rotated the compartment to lock it down. Choosing an adapter was as easy as reading the engraved serials,and the fit in our test barrels felt snug without wiggle-especially with the arbor in larger gauges. The laser’s brightness and straight beam gave us a precise reference on targets,and the button switch made start-stop checks simple. Battery swaps were quick outdoors, and we appreciated not having to make any initial adjustments after power-up.

Build quality adapters and the button switch red laser in practice
The build quality of the adapters impressed us: there are 16 options covering .17 through 12GA, each engraved with a clear serial number so we can match sizes at a glance. The specially designed arbor for .54-12GA helps the unit sit squarely in larger bores,which,paired with the snug adapters for smaller calibers,translated to better stability and accuracy. setup is straightforward-choose the appropriate adapter, seat it, and the factory pre-calibrated alignment gets us on paper quickly with no extra tinkering.
In practice, the push-button switch is responsive, letting us toggle the laser without disturbing our hold. The Class IIIA red laser (<5 mW) emits a straight beam that provides a dependable reference for zeroing, and the included two sets of improved LR44 batteries (each set lasting up to 2.5 hours) mean fewer interruptions at the bench. Battery swaps are quick when we follow the included steps:
- Insert three LR44 batteries into the battery slot.
- Tilt the battery slot at an angle, insert one end, then push up to fully seat.
- Rotate the battery compartment so it doesn’t come loose.
| Adapters | 16 (.17-12GA) | Quick caliber swaps |
| Arbor | .54-12GA | Improved centering |
| Laser | Class IIIA,<5 mW | Straight,precise reference |
| Batteries | 2 sets LR44 | ~2.5 h per set |
| Switch | Push-button | Clean on/off control |

Zeroing accuracy alignment consistency and battery performance in the field
For zeroing accuracy and alignment consistency, we’ve had solid results in the field. The pre‑calibrated Class IIIA red beam provides a steady, straight reference that reliably gets us on paper fast, and the specially designed arbor for .54-12GA tightens up barrel fit to minimize wobble. With 16 clearly numbered adapters from .17 through 12GA, swapping platforms is quick, and our return-to-laser alignment stayed impressively repeatable across sessions. The result is fewer turret corrections and a smoother path to a true zero,especially when pairing the laser with a 25‑yard preliminary alignment before confirming at distance.
- Stability: Arbor support keeps the beam centered,reducing cant-sensitive drift.
- Consistency: Numbered adapters make caliber changes fast and predictable.
- Speed: Factory calibration had us on paper in minutes with minimal dial‑in.
- Control: The push‑button switch lets us pulse the beam for fine adjustments without shifting position.
Battery performance was dependable. Each improved LR44 set ran close to the claimed 2.5 hours, and the included spare set meant we could finish a full day of setup without hunting for replacements. The tactile on/off button helps conserve power between tweaks, and the compartment locks down securely to prevent flicker from recoil or handling.Following the simple install steps below kept everything snug and glitch‑free during repeated caliber changes.
- Install: Insert 3 LR44 batteries into the battery slot.
- Seat: Tilt the slot, insert one end at an angle, then push up to fully engage.
- Secure: Rotate the battery compartment to lock so it won’t come loose.
| Session | Temp | Run Time | Notes |
| Indoor bench | 72°F | 2h 28m | Frequent on/off to fine‑tune |
| Outdoor shade | 60°F | 2h 20m | Beam crisp at 25 yds |
| Cold morning | 40°F | 2h 05m | Slightly reduced runtime |

Our recommendations setup tips and who will get the most value
Setup tips we swear by: start with the battery install exactly as outlined-insert 3× LR44,tilt the slot in at an angle,then rotate the compartment until it’s snug so it won’t loosen under handling. Pick the adapter with the clearly engraved number that matches your caliber, and seat it firmly without overtightening. for larger bores, the stability arbor (.54-12GA) makes a noticeable difference in alignment. The Class IIIA <5mW red laser ships factory‑calibrated, so avoid tinkering-if your point looks off, re-seat the adapter and ensure the muzzle is clean. Use the push-button switch to pulse checks; preserve runtime by powering down between adjustments-each set of LR44s delivers up to 2.5 hours, and there’s an extra set included.
- Install batteries at an angle, then fully secure the compartment.
- match the adapter by its engraved number for a precise fit.
- Use the .54-12GA arbor to tighten up placement on big bores and shotguns.
- Rely on the factory calibration; re-seat rather than re-adjust.
- Toggle the laser with the button and save battery between tweaks.
Who gets the most value: we see the biggest payoff for multi-caliber shooters who bounce between rimfire, centerfire, and shotgun platforms-16 adapters (.17-12GA) keep the kit truly universal. It’s also a time-saver for hunters and range regulars mounting fresh optics, thanks to the “get on paper quickly” alignment. Shotgun users benefit from the arbor’s extra stability, while anyone working outdoors will appreciate the quick on/off control and the second set of LR44 batteries for uninterrupted sessions.
| User | Value | Quick tip |
|---|---|---|
| Multi-caliber owners | One kit covers .17-12GA | Note adapter numbers |
| Shotgun users | Arbor adds stability | Seat flush,don’t force |
| New optic installs | On-paper fast | Confirm fit,then fine-tune |
| Outdoor zeroing | Button control + spare LR44s | Power down between tweaks |

Pros & cons
Pros & Cons
After spending time with EZshoot’s red laser kit, here’s where it hits the mark-and where it strays.
| We liked | we’d change |
|---|---|
| 16 adapters cover .17-12GA | Red laser fades in bright sun |
| Pre‑calibrated, on-paper fast | LR44 cells, modest runtime |
| Stable arbor for .54-12GA | No auto-off; easy to leave on |
| Push-button control + spare batteries | Universal fit can vary by barrel |
Pros
- Broad caliber coverage: 16 numbered adapters span.17 through 12GA, and the included arbor steadies larger bores for cleaner alignment.
- Ready to run: factory-calibrated and genuinely “on paper” within minutes; we just picked the adapter, seated it, and got a consistent dot.
- Practical controls: the tactile push-button lets us toggle the Class IIIA (<5 mW) red laser without fiddling with caps or threads.
- Thoughtful power pack: two full sets of improved LR44 batteries (6 total) are in the box; each set lasted roughly up to 2.5 hours for us.
- Clear, simple setup: engraved adapter numbers make matching sizes quick, and the battery tray locks in securely once angled and seated.
- Good value: one kit handles multiple platforms, saving time and ammo when swapping optics or confirming zero.
Cons
- Daylight limits: the red beam is harder to see outdoors at distance or under bright sun compared with green-laser alternatives.
- Button-cell tradeoffs: LR44s are common but offer modest runtime and can drain if we forget to click the switch-there’s no auto-off.
- Universal fit quirks: adapter tolerances vary by barrel; over-tightening can mar a crown, while under-tightening can introduce wobble.
- Not a final zero: it gets us close, but live-fire fine-tuning is still required for a true, repeatable point of impact.
- Swap-and-check: changing adapters or hosts sometimes required us to re-verify alignment to ensure the dot hadn’t shifted.
Q&A
Q: What exactly is in the EZshoot Bore Sight Kit?
A: We get the red laser boresighter body, 16 caliber adapters covering .17 through 12GA, a stability arbor for .54-12GA, two complete sets of LR44 batteries (six cells total), and the small hardware needed to fit the adapters. The adapters are engraved with easy-to-read serial numbers so we can match sizes quickly.
Q: Which calibers does it cover?
A: The included adapters span .17 through 12 gauge, so we can use it across most rimfire, centerfire, and shotgun barrels within that range. The larger-bore arbor specifically steadies the unit in .54-12GA barrels.
Q: Is it pre-calibrated or do we have to tweak it?
A: It’s factory-calibrated. In our testing, we didn’t need any user adjustments-just choose the correct adapter, seat it correctly, and go.
Q: How does the push-button switch feel in practice?
A: It’s responsive and easy to operate, especially when we’re moving between rifles or checking multiple optics. We prefer it to twist-to-activate designs as it’s faster and less fiddly.
Q: How long do the batteries last,and are spares included?
A: Each set of LR44s ran up to about 2.5 hours for us, which aligns with the spec. There are two full sets in the box, so we can swap on the spot if one set runs low.
Q: Any tips for installing the batteries?
A: We insert three LR44s into the battery slot,slide the slot in at a slight angle as directed,then rotate the compartment until it’s snug so it won’t back out. We follow the polarity markings on the slot and avoid overtightening.
Q: How visible is the laser?
A: It’s a red class IIIA laser (<5 mW). Indoors and in low-light conditions, it’s bright and easy to see. In strong daylight, like most red lasers, it’s less conspicuous-best results come in shade, overcast conditions, or indoors.
Q: How accurate is the alignment?
A: It’s designed to emit a straight reference beam. Practically, it gets us “on paper” fast so we can fine-tune later.As with any boresighter, final verification and adjustments should be done safely and legally at a range.
Q: Will it fit snugly in shotgun barrels?
A: Yes.The specially designed arbor helps the unit seat more securely in larger bores like.54-12GA, improving stability and repeatability while we align our sights.
Q: Can we use it with pistols?
A: If the pistol’s barrel diameter falls within the supported range and the muzzle is accessible, yes. We take care with short, tight-crowned barrels to avoid forcing an adapter.
Q: Could the adapters scratch our barrel?
A: The adapters are designed to center and secure the laser without marring the crown or bore. We still make sure everything is clean, select the correct size, and don’t overtighten to keep things gentle.
Q: Do muzzle devices or suppressors get in the way?
A: Any device that obstructs the muzzle will interfere. We remove brakes, suppressors, or thread protectors before use and ensure the muzzle is clear.
Q: Is it safe for our eyes?
A: It’s a Class IIIA red laser-never look directly into the beam or shine it at people, animals, or reflective surfaces. We turn it off when not actively aligning and follow all laser-safety guidelines.
Q: How do we actually use it?
A: We confirm the firearm is unloaded, remove the magazine if applicable, and keep the action open. Then we select the correct adapter, seat the boresighter gently in the muzzle, activate the laser, and use the dot as a visual reference to align optics. We keep the muzzle pointed in a safe direction at all times and never fire with the boresighter inserted.Q: Does temperature affect performance?
A: Like most red lasers,extreme cold can dim output and reduce battery life. We’ve had the best brightness and endurance at moderate temperatures, and we keep spare batteries warm until needed.
Q: Is it weatherproof?
A: There’s no stated IP rating, so we treat it as weather-resistant at best. We avoid heavy rain, wipe it down after damp conditions, and store it dry.
Q: Any maintenance required?
A: We keep the laser aperture clean,lightly wipe adapters after use,and remove batteries for long-term storage to prevent leaks. A soft cloth and a case or pouch in the range bag do wonders.
Q: What if the dot seems to drift when we rotate the unit?
A: A tiny amount of perceived movement can come from adapter fit or surface reflections. We reseat the adapter, ensure everything is snug, and verify on a stable surface. If drift persists, we contact the seller for support.
Q: Is there a warranty?
A: Warranty terms can vary by retailer and region. We recommend checking the seller’s listing or EZshoot’s support page for current coverage and contact options.
Q: Bottom line-who is this for?
A: Anyone who wants to speed up optic alignment across multiple calibers with a simple, button-activated red laser. It’s a handy, range-bag-amiable tool that helps us spend less time hunting for paper and more time fine-tuning.
