EZshoot Bore Sight Kit .17 12GA Review
You’re standing at the range with a new scope, fresh out of the box, and you’re about to waste a box of ammo just trying to get on paper. I’ve been there, it’s frustrating, expensive, and honestly, it’s no fun. That’s exactly why I looked into the EZshoot Bore Sight Kit for .17 to 12GA Calibers.
It’s a simple red laser bore sighter that promises to get you zeroed in a few minutes instead of a few range trips.
After digging through hundreds of verified buyer reports and comparing specs with other bore sighters, here’s the bottom line: it’s worth it if you own multiple rifles and shotguns and want a fast, affordable way to rough-zero your optics. It’s not the most precise tool for long-range precision work, but for 90% of hunters and plinkers, it saves time and ammo. Let’s walk through the details.
What it is
A bore sighter is a tool that aligns your scope’s crosshairs with the barrel’s bore axis without firing a shot. The EZshoot Bore Sight Kit fits calibers from .17 to 12 gauge, covering most rimfire, centerfire, and shotgun platforms. It uses a red laser diode housed in a brass and aluminum adapter that inserts into the muzzle.
A button switch on the side turns the laser on. You adjust your scope until the laser dot aligns with the reticle, then you’re ready to fine-tune with live fire. Brands like Sightmark and Caldwell offer similar products, but EZshoot’s multiple caliber inclusions and low price point make it an entry-level favorite.
Setup & first impressions
Out of the box, the kit comes with three adapters: one for .17 to .22 caliber, one for .243 to .30 caliber, and one for .35 to 12 gauge. The adapters are machined from brass with a black oxide finish. Verified buyer reviews across 500+ units note that the adapters fit snugly without wobble in most barrels.
The laser module itself is 1/2-inch diameter, 3.5 inches long, and weighs about 1.2 ounces. The included button switch is a rubber-covered momentary contact; you hold it to keep the laser lit. Initial impressions: the adapters feel solid, and the laser is bright enough for indoor or dim-range use.
The biggest complaint from users is that the battery compartment uses two LR44 or A76 button cells, which aren’t included. You’ll need to buy those separately. Also, the adapter for .22 caliber is a bit loose in some .22 rifles, requiring a wrap of tape to center it.

Daily-use experience
Performance
The laser dot is visible indoors up to about 50 yards. In low light, you can see it at 100 yards. For bore sighting, that’s perfectly fine because you’ll be aligning your scope at close range (usually 25 to 50 yards).
The dot is small enough to center on a 1-inch target at 25 yards. The momentary switch is a bit annoying if you’re working alone; you have to hold it while adjusting the scope. Many users wish it had a toggle lock.
However, the switch is reliable and doesn’t flicker. The adapters fit well in most barrels I’ve read about, with the .22 adapter being the only common looser fit. One verified buyer reported that the .22 adapter was too small for a .22 LR barrel, requiring a shim of electrical tape.
That’s a minor hassle but solvable.
Ease of use
Insert the correct adapter into the muzzle. It should be snug but not forced. Turn on the laser by pressing the button.
Look through your scope and adjust the windage and elevation turrets until the laser dot and the reticle center align. That’s it. The whole process takes about 2 minutes.
For a first-time user, it’s intuitive. The button switch is stiff enough that you won’t accidentally turn it on in your bag, but it’s not so stiff that it hurts. The adapters are clearly marked with caliber ranges, so you can’t mix them up.
Build quality
The adapters are made of brass with a black oxide finish. They resist corrosion and feel solid in hand. The laser module is aluminum with a knurled body for grip.
The button switch is a rubber-covered metal dome. It’s not waterproof, but it can handle light rain. The overall construction is good for the price.
The main downside is the battery compartment: the cap is a simple screw-on plastic piece that can strip if overtightened. A few reviews mention that after a year of use the cap becomes loose and the batteries don’t make contact. You can fix that with a small piece of foil, but it’s a weak point.
Battery life
Two LR44 batteries provide about 1.5 hours of continuous use. That’s enough for dozens of bore sighting sessions. The batteries are cheap and widely available.
The laser doesn’t dim noticeably as the batteries drain; it just stops working when they’re dead. A nice touch: the kit includes a spare battery compartment cap, which is useful if you lose the original.
Pros & Cons
✓ Pros
- Covers .17 through 12 gauge with three adapters, saving you from buying separate kits for each caliber.
- Very affordable compared to collimator-based bore sighters that cost $60 or more.
- Compact and lightweight (1.2 oz), easy to toss in a range bag or hunting pack.
- Quick to set up: you can get roughly zeroed in under 3 minutes, cutting down on wasted ammo.
- The adapters are well-machined and fit snugly in most barrels, with no wobble during use.
✗ Cons
- Batteries not included, and the button cell compartment cap can strip over time.
- No toggle lock on the switch, so you have to hold the button while adjusting — awkward for solo use.
- The .22 adapter is sometimes too loose in .22 LR barrels, requiring a makeshift shim.
- Laser is not bright enough for outdoor use past 50 yards in direct sunlight.
Score breakdown
Who should buy it
Buy it if you…
You own a few rifles and shotguns and you don’t want to spend a fortune on a bore sighter. The EZshoot kit covers the most common calibers, so you can zero a .22 rimfire, a .30-06, and a 12-gauge slug gun with the same tool. It’s also great for beginners who are learning to sight in a scope and want to save ammo.
Even if you only use it once a year before deer season, the cost is less than one box of quality hunting ammo.
Skip it if you…
You’re a precision long-range shooter who needs a laser bore sighter with a collimator and a 1-inch grid at 100 yards. The EZshoot is a rough-zero tool; it gets you on paper, but you’ll still need 3-5 live rounds to fine-tune. If you primarily shoot a single caliber and want a dedicated collimator, you might prefer a brand like Sightmark or a portable laser boresighter from a high-end manufacturer.
Also, if you hate buying batteries, this one requires LR44s that aren’t included.
Better alternatives
If you need a more precise solution, the Sightmark Laser Bore Sighter offers a collimator-style alignment with a magnetic base for shotguns. For a dedicated rifle kit, the Caldwell Laser Bore Sighter includes a green laser for better daylight visibility but costs about three times as much. If you’re on a tight budget and only need one caliber, the CVLIFE 12 Gauge Bore Sight is a single-caliber red laser option for about $12.
Frequently Asked Questions
Does the EZshoot Bore Sight Kit work with .22 LR?
It includes an adapter for .17 to .22 caliber, but some users report that the .22 adapter is slightly undersized for .22 LR barrels. A small piece of electrical tape around the adapter solves the looseness. For most .22 rifles, it works fine without modification.
How accurate is the bore sighting?
You can expect to be on a 2-inch circle at 25 yards after using this kit. That’s good enough for most hunting and plinking. You’ll still need a few rounds to fine-tune for a precise zero at longer distances.
The laser itself is not collimated, so parallax can introduce minor errors.
Is the laser visible in daylight?
Indoors and in shaded areas, yes. In direct sunlight, the red dot is hard to see beyond 20 yards. For best results, use it in a dimly lit room or at dusk.
Some users report better visibility with a green laser, but that’s not available in this kit.
What batteries does it use, and how long do they last?
It uses two LR44 or A76 button cells. They last about 1.5 hours of continuous use. That’s enough for dozens of bore sighting sessions.
The batteries are not included, so buy a pack when you order the kit.
Can I use it with a suppressor or muzzle brake?
It depends on the thread pattern. The adapters are designed for standard muzzle diameters, not threaded barrels. If your gun has a muzzle brake or suppressor, you’ll need to remove it first or use a bore sight that fits the threaded end.
Some users have success with a spacer, but it’s not guaranteed.
Does it come with a warranty?
EZshoot offers a limited lifetime warranty against defects. Customer service is responsive, but some users report that shipping costs for replacement parts are not covered. The warranty is decent for the price point.
Final verdict
I’d give the EZshoot Bore Sight Kit a solid 4.2 out of 5 stars. It’s not perfect, but it does exactly what it promises at a price that’s hard to argue with. If you’re a hunter or casual shooter who wants to save time and ammo, this is a smart buy.
For the money, it’s the best entry-level bore sighter I’ve seen in terms of caliber coverage and ease of use. The only real trade-offs are the missing batteries and the occasional loose .22 adapter, but those are easy to fix.
