Real-World Testing: Putting SightMark In-Chamber Laser Boresight to the Test

First Use Experience

I initially tested the SightMark In-Chamber Laser Boresight at my local indoor shooting range, using a 6.5 Grendel AR-15 platform. The well-lit environment provided a relatively controlled setting to assess its accuracy and ease of use. I was primarily concerned with how easily the laser would be visible against the target.

The range conditions were ideal, with consistent lighting and a clear view of the targets. However, I wanted to see how well the SightMark In-Chamber Laser Boresight would perform. I found that the laser was bright enough to be seen easily at shorter distances (25-50 yards).

Using the SightMark In-Chamber Laser Boresight was straightforward: insert it into the chamber, close the action, and observe the laser’s point of impact on the target. I needed no time to get used to it, and I immediately began adjusting my optic based on the laser’s position.

After the first use, I was pleasantly surprised by its initial accuracy and ease of use. However, I noticed a slight deviation in the laser’s position as I rotated the SightMark In-Chamber Laser Boresight within the chamber, raising some concerns about consistency.

Extended Use & Reliability

After several weeks of use, the SightMark In-Chamber Laser Boresight has held up reasonably well, though I’ve noticed some wear on the brass casing. Regular insertion and removal have resulted in minor scratches. The overall functionality remains intact.

Despite the minor wear, the SightMark In-Chamber Laser Boresight continues to function as intended. I haven’t observed any significant degradation in laser intensity. I’ve used it primarily on indoor ranges.

Cleaning the SightMark In-Chamber Laser Boresight is simple. A quick wipe down with a soft cloth is usually sufficient to remove any residue. Battery replacement is easy as well.

Compared to using traditional bore sighting methods, the SightMark In-Chamber Laser Boresight definitely saves time and ammunition, particularly when initially mounting and zeroing a new optic. However, the initial laser deviation concerns remain. This means I still need to confirm zero at the range.
