Sightmark Laser Bore Sight, 243 Win, SM39005 – 1 out of 29 models Review

Let’s Dive into Sightmark Laser Bore Sight, 243 Win, SM39005 – 1 out of 29 models

The Sightmark Laser Bore Sight, 243 Win, SM39005 – 1 out of 29 models, from Sightmark, promises a faster and more economical way to zero your rifle. This tool eliminates the need for excessive ammunition and range time, a particularly attractive proposition for seasoned hunters and competitive shooters alike. It’s a simple concept: a laser that simulates the path of a bullet to get you on paper before live fire.

As a long-time shooter, I’ve always sought efficient methods to minimize wasted ammo and range frustration. I’ve seen bore sighting tools that range from crude mechanical contraptions to sophisticated optical devices, so I was eager to evaluate where the Sightmark offering fell on the spectrum. My initial impression was of a compact, seemingly well-made device, promising quick results for the popular .243 Winchester caliber.

I’ve used similar laser bore sights in the past, but their reliability was often questionable. Some had loose battery compartments, others emitted a dim, inconsistent laser, and still others simply failed after minimal use. In contrast, the Sightmark unit seemed more robust right out of the package. My hope was that it would offer a consistently bright and accurate laser projection.

Compared to magnetic bore sights, which I often find cumbersome to align, this chamber-insert design seemed more straightforward. I’ve also considered more expensive optical bore sighting systems, but their price point makes them less appealing for occasional use. The Sightmark appeared to strike a balance between affordability and practicality.

My initial excitement was tempered by a healthy dose of skepticism. Bore sighting is an inexact science, and I wondered how accurate the Sightmark Laser Bore Sight would truly be. I hoped it would at least get me close enough to zero with minimal adjustments at the range, and save precious daylight during hunting season.

Real-World Testing: Putting Sightmark Laser Bore Sight, 243 Win, SM39005 – 1 out of 29 models to the Test

First Use Experience

I tested the Sightmark Laser Bore Sight at my local shooting range, a facility offering distances up to 200 yards. The weather was clear and mild, ideal for sighting in a rifle. I used it on my trusty Remington 700 in .243 Winchester, a rifle I’ve relied on for years for deer hunting.

The bore sight was incredibly easy to use. I simply chambered it like a regular cartridge, closed the bolt, and the laser dot appeared on the target 50 yards downrange. The laser was bright and clearly visible, even in daylight. After adjusting my scope to align with the laser dot, I fired three shots. They landed within a few inches of the bullseye.

There were no immediate issues or surprises. The Sightmark performed exactly as advertised, quickly getting me on paper. The process was faster and less wasteful than the traditional method of trial and error.

Extended Use & Reliability

After several months of use, the Sightmark Laser Bore Sight continues to perform reliably. I’ve used it to sight in several .243 rifles, and it has consistently delivered good results. The aluminum casing shows no signs of wear and tear, even after being tossed in my range bag.

Cleaning is simple; I just wipe it down with a clean cloth after use. The battery life seems reasonable. I’m still on the original set of batteries after multiple uses. Compared to my previous experiences with other bore sights, the Sightmark has exceeded my expectations in terms of both accuracy and durability.

Performance & Functionality

The Sightmark Laser Bore Sight excels at quickly getting you on paper. It significantly reduces the amount of time and ammunition required to zero your rifle. The bright red laser is easy to see and use, even for novice shooters. While it doesn’t replace the need for live fire zeroing, it provides an excellent starting point.

The primary weakness is that bore sighting, in general, isn’t a perfect science. Factors like barrel harmonics and bullet trajectory still require fine-tuning with live rounds. However, the Sightmark dramatically reduces the amount of adjustment needed, making it a worthwhile investment. It definitely met my expectations for a quick and easy initial zeroing.

Accessories and Customization Options

The Sightmark Laser Bore Sight comes with a basic carrying case for protection. There are no specific customization options available for the unit itself. It’s designed to be a standalone tool for bore sighting.

However, its effectiveness can be enhanced by using it in conjunction with a stable shooting rest and a high-quality scope. While not directly compatible, the laser’s visibility can be further improved using laser enhancement glasses, especially in bright daylight.
