Let’s Talk About JE Machine Tech 5mW Laser Boresighter
The JE Machine Tech 5mW Laser Boresighter promises a quick and easy way to get your firearms roughly zeroed, saving valuable time and ammunition at the range. Manufactured by JE Machine Tech, this aluminum-bodied device emits a red laser beam, theoretically allowing users to align their sights or optics with the bore of their firearm. For a budget-friendly price of $16.99, it seems like an attractive solution for both seasoned shooters and newcomers alike.
As an experienced outdoor and tactical gear specialist, I’m always on the lookout for affordable tools that can simplify firearm maintenance. The promise of a quick boresight was exactly what I needed; range time is precious, and reducing the initial sighting-in process appealed to me. I was eager to test if this little gadget could deliver on its promises.
Unboxing the JE Machine Tech 5mW Laser Boresighter revealed a lightweight aluminum cylinder. It felt surprisingly cheap, to be honest, but for the price, I wasn’t expecting aerospace-grade materials. My initial concern was the long-term durability, especially considering the potential for tight chamber fits.
Compared to more robust magnetic boresighters from brands like SiteLite or Bushnell, this JE Machine Tech offering seemed almost disposable. I chose this one for the price point, hoping to find a budget option that could still get the job done for casual range trips. Honestly, my first impression was one of cautious optimism mixed with a healthy dose of skepticism.
Real-World Testing: Putting JE Machine Tech 5mW Laser Boresighter to the Test
First Use Experience
I first tested the JE Machine Tech 5mW Laser Boresighter at an outdoor shooting range on a clear, sunny day. I brought along my AR-15 chambered in .223 Wylde, which I had recently installed a new scope on, as well as my AK-47 chambered in 7.62×39. The intention was to use the boresighter to get both rifles on paper before fine-tuning with live ammunition.
The boresighter worked as expected in the AR-15 initially. The red dot was easily visible on the target at 25 yards, and I was able to adjust my scope to roughly align with the laser. When I attempted to use the same boresighter in my AK-47, however, the issues started.
I was able to get the boresighter into the chamber, but after the bore sighting was finished, I could not remove it. I had to tap it out with a cleaning rod, ruining it completely. It was a one-time use product.
Extended Use & Reliability
Frankly, due to the issues I encountered during my first use with my AK-47, extended use wasn’t really an option. The aluminum construction proved to be far too soft, and the device essentially self-destructed during removal. This severely impacted my confidence in its long-term reliability.
Durability is a major concern given the soft aluminum. It’s prone to deformation, especially if the chamber fit is even slightly tight. Maintenance is non-existent, as any attempt to disassemble or repair the boresighter will likely result in further damage.
Compared to my experiences with magnetic boresighters (which, granted, are significantly more expensive), the JE Machine Tech offering is a major disappointment. The magnetic models are far more versatile, more durable, and don’t risk getting stuck in the chamber. This product underperformed in every aspect.
Breaking Down the Features of JE Machine Tech 5mW Laser Boresighter
Specifications
- Manufacturer: JE Machine Tech.
- Fabric/Material: Aluminum.
- Beam Color: Red.
- Additional Features: 635-655 nm Wavelength.
- Power: 5 mW.
- Condition: New.
- Battery Quantity: 3.
- Battery Life: 1.5-2 hours if continuously left on.
- Power Source: Three(3) LR41/LR44 button cell batteries (or equivalent).
- Minimum sighting range: 15 yards.
- Wavelength: 625-660 nm.
- Output power: less than 5mW.

The specifications highlight the simplicity of the boresighter. The aluminum body keeps the cost down, but sacrifices durability. The 5mW red laser is adequate for short-range bore sighting in daylight, though visibility might be an issue in brighter conditions.
Performance & Functionality
When it works, the JE Machine Tech 5mW Laser Boresighter does provide a basic visual reference for aligning sights. However, the inconsistent fit across different firearms, coupled with the fragile construction, makes its performance unreliable. The risk of the device getting stuck in the chamber outweighs the convenience it offers.
Its primary strength is its affordability. It’s a very cheap option. The significant weakness is its poor construction and the high risk of damaging it or getting it stuck. It definitely does not meet expectations for a reliable bore sighting tool.
Design & Ergonomics
The design is simple: a cylindrical aluminum housing with a laser diode and battery compartment. The light weight might seem like a plus, but it contributes to the overall feeling of cheapness. There’s no real ergonomics to speak of; it’s simply a tube that fits (or attempts to fit) into the chamber.
The build quality is where the boresighter falls short. The soft aluminum is easily deformed, and the lack of precise machining contributes to the inconsistent fit. The user-friendliness is debatable; while the concept is simple, the risk of getting it stuck significantly complicates the process.
Durability & Maintenance
The JE Machine Tech 5mW Laser Boresighter’s lifespan is likely to be very short. Especially if used across multiple firearms. Maintenance is virtually impossible; any attempt to disassemble or clean the device will likely cause further damage.
Its lack of durability renders it essentially a disposable item.
Accessories and Customization Options
The boresighter comes with no accessories beyond the batteries required for operation. There are no customization options available or necessary. The device is intended as a standalone tool with limited functionality.
It is not compatible with any aftermarket accessories. Its simplicity and intended use case preclude any need for customization.
Pros and Cons of JE Machine Tech 5mW Laser Boresighter
Pros
- Extremely affordable. The low price point is the primary selling point.
- Simple to use in theory. Once inserted (and if it doesn’t get stuck), it provides a visual reference.
- Lightweight. Easy to carry in a range bag.
Cons
- Very poor durability. The soft aluminum construction is prone to damage.
- High risk of getting stuck in the chamber. A common complaint among users.
- Inconsistent fit across different firearms. May not work reliably with all chambers.
Who Should Buy JE Machine Tech 5mW Laser Boresighter?
The JE Machine Tech 5mW Laser Boresighter might be suitable for the extremely budget-conscious shooter who only needs to boresight a single firearm with a known, loose chamber tolerance. If you can verify it fits easily before inserting it.
Anyone who owns multiple firearms or values durability and reliability should skip this product. The risk of damaging the device or their firearm is too high.
A higher-quality magnetic boresighter is a must-have accessory as an alternative to this boresighter.
Conclusion on JE Machine Tech 5mW Laser Boresighter
The JE Machine Tech 5mW Laser Boresighter offers a tantalizingly low price point, but ultimately fails to deliver on its promise of a quick and easy bore sighting solution. The poor construction, risk of getting stuck, and inconsistent fit make it a frustrating and potentially damaging tool. It’s a classic case of getting what you pay for.
The price is not justified, even at $16.99, considering the high risk of failure and the limited lifespan. I would not personally recommend this product.
Save your money and invest in a more reliable bore sighting solution. The JE Machine Tech 5mW Laser Boresighter is more likely to cause headaches than help you zero your rifle.
