Sightmark 7.62 x 39mm 5mW Red Laser Boresighter Review

First Thoughts on the Sightmark 7.62 x 39mm 5mW Red Laser Boresighter

The Sightmark 7.62 x 39mm 5mW Red Laser Boresighter promises a quicker, more efficient way to zero your rifle. Sightmark is a brand known for offering affordable optics and accessories, and this boresighter fits that bill. I was intrigued by the potential to save ammo and range time, especially when working with my SKS and AK platform rifles, both chambered in 7.62x39mm.

I’ve always relied on traditional methods of sighting-in, which, let’s be honest, involves a lot of guesswork and wasted rounds. The allure of a laser boresighter was simple: get on paper faster and fine-tune from there. My goal was to find a tool that could significantly reduce the time and ammunition needed to establish a reliable zero on my rifles.

Upon receiving the Sightmark 7.62 x 39mm 5mW Red Laser Boresighter, I was immediately struck by its brass construction. It felt solid and well-made for the price. Compared to some cheaper, polymer alternatives I’ve seen, this seemed like a step up in quality.

I considered other laser boresighters, including some magnetic muzzle-mounted options. However, I opted for the Sightmark chamber-style boresighter due to its perceived ease of use and potential for better accuracy. This model seemed more straightforward and less prone to misalignment than the muzzle-mounted types.

My initial impression was one of cautious optimism. I was excited to try it out but also slightly skeptical about how accurately it would align with the actual bore. The promise of a quick and easy sighting process was definitely appealing.

Real-World Testing: Putting Sightmark 7.62 x 39mm 5mW Red Laser Boresighter to the Test

First Use Experience

My first experience with the Sightmark 7.62 x 39mm 5mW Red Laser Boresighter was at my local outdoor shooting range. The weather was clear and sunny, perfect conditions for sighting in a rifle. I was eager to see if it lived up to the hype.

Using the boresighter was incredibly straightforward. I simply chambered it like a regular cartridge, and the red laser dot appeared on the target downrange. The simplicity of use was immediately apparent.

I did experience a slight issue with the laser’s visibility at 100 yards in bright sunlight. However, at 25 yards, it was clearly visible and provided a solid reference point for adjusting my sights. I quickly adjusted my scope to align with the laser dot.

After making adjustments based on the boresighter, my first three shots at 25 yards were surprisingly close to the bullseye. I only needed minor adjustments to achieve a tight group. This saved me a considerable amount of time and ammunition compared to my usual process.

Extended Use & Reliability

After several months of regular use, the Sightmark 7.62 x 39mm 5mW Red Laser Boresighter has proven to be a reliable tool. It consistently provides a close approximation of my rifle’s point of impact. This gets me on paper quickly.

The brass construction has held up well. There are no signs of significant wear and tear despite repeated use and storage in my range bag. It feels as solid now as it did when I first unboxed it.

Maintaining the boresighter is simple. I wipe it down with a clean cloth after each use to remove any residue or debris. Replacing the AG3 batteries is also easy, although I haven’t needed to do so very often.

Compared to my previous method of sighting in (trial and error with live rounds), the Sightmark boresighter has significantly improved my efficiency. It’s not a replacement for fine-tuning at the range. However, it dramatically reduces the initial time and ammunition wasted getting on paper.
