Let’s Dive into Sightmark Laser Bore Sight, 12 Gauge, SM39007 – 1 out of 29 models
The Sightmark Laser Bore Sight, 12 Gauge, SM39007 – 1 out of 29 models, from Sightmark, promises a quicker, easier, and more economical way to zero your shotgun. It’s a simple concept: a laser housed in a 12-gauge shell that lets you align your sights without firing a single round. The lure of saving time, money (on ammo), and shoulder abuse definitely piqued my interest after years of struggling with traditional sighting methods.
For years, I’ve struggled with sighting in shotguns the old-fashioned way, burning through boxes of shells and ending up with a bruised shoulder. The promise of a faster, less painful, and more precise method drew me to this particular bore sight.
Upon unboxing, the Sightmark bore sight felt solid, though surprisingly light. The construction appears to be decent quality, especially considering the price point, but the plastic housing does raise some initial concerns about long-term durability.
I’ve used magnetic bore sights in the past, and while they worked okay for rifles, they were useless for shotguns due to the lack of a flat surface on the barrel. The shell-based design of the Sightmark seemed like a far more practical solution for my 12-gauge. My first impression was cautiously optimistic; I was excited to try it out, but the lightweight construction had me wondering if it could truly withstand repeated use.
Real-World Testing: Putting Sightmark Laser Bore Sight, 12 Gauge, SM39007 – 1 out of 29 models to the Test
First Use Experience
I first tested the Sightmark Laser Bore Sight at my local shooting range. It was a relatively clear day, which aided in visibility of the laser dot.
The Sightmark bore sight slipped easily into the chamber of my Remington 870. The laser was clearly visible at 25 yards, making initial adjustments surprisingly easy. I did notice that the laser dot wasn’t perfectly centered, which required some experimentation to understand how to compensate for the offset.
Extended Use & Reliability
After several weeks of using the Sightmark, I’ve come to appreciate its convenience but also recognize its limitations. The plastic housing has held up fine so far, with no visible cracks or damage. However, I’m still cautious about how it will handle extreme temperatures.
Cleaning is simple: just wipe it down with a clean cloth. It has definitely sped up the initial sighting-in process, although fine-tuning with live rounds is still essential. Compared to burning through dozens of shells, the Sightmark has significantly reduced the amount of ammo required, saving both time and money.
Breaking Down the Features of Sightmark Laser Bore Sight, 12 Gauge, SM39007 – 1 out of 29 models
Specifications
Caliber: 12 Gauge. This is the critical dimension, ensuring it fits properly in your shotgun’s chamber.
Laser Wavelength: Typically 630-670nm (Red). This indicates the color and visibility of the laser, with red being common and generally adequate for indoor and daylight use.
Power Output: Less than 5mW. This is a safety rating, ensuring the laser is not harmful to the eyes.
Battery Type: Usually button cell batteries (e.g., LR44 or similar). These batteries are small and readily available, but battery life can be a concern.
Material: Primarily plastic housing. The plastic construction keeps the cost down but raises concerns about durability.
These specifications are important because they determine the compatibility, visibility, and overall usefulness of the bore sight. The 12-gauge specification ensures it fits your shotgun. The laser wavelength and power output impact its visibility in different lighting conditions.
Performance & Functionality
The Sightmark Laser Bore Sight performs its primary job – getting you close to zero – reasonably well. Accuracy is sufficient for initial sight alignment, but it’s not a replacement for live-fire fine-tuning.
Its strength is in saving time and ammunition, getting you on paper quickly. Its weakness lies in the fact that it isn’t a perfect replacement for actually shooting the gun. It meets expectations for a budget-friendly bore sight, but don’t expect pinpoint accuracy.
Design & Ergonomics
The plastic housing is lightweight and easy to handle, but it doesn’t inspire confidence in terms of long-term durability. The battery compartment is easily accessible.
There’s no learning curve – you simply chamber it like a shell. However, the laser dot’s potential offset requires understanding and compensation.
Durability & Maintenance
The plastic construction raises concerns about its lifespan, especially with repeated chambering. Maintenance is minimal; just keep it clean and store it properly.
Repair isn’t really an option; if it breaks, you’ll likely need to replace it. The key is to handle it with care and avoid rough handling.
Accessories and Customization Options
The Sightmark Laser Bore Sight comes with a small carrying pouch. There aren’t any customization options.
It’s designed as a standalone tool, focusing solely on bore sighting. While you could use it in conjunction with other sighting tools, its primary function is self-contained.
