Sightmark Laser Bore Sights Review

Let’s Dive into Sightmark Laser Bore Sights

The Sightmark Laser Bore Sights promise a quick and easy way to get your firearms roughly zeroed before heading to the range, saving both time and valuable ammunition. Manufactured by Sightmark, these caliber-specific bore sights insert directly into the chamber and project a laser beam downrange, allowing for initial scope or sight adjustments. As an experienced firearms enthusiast, the promise of reducing range time wasted on initial zeroing attempts immediately piqued my interest.

Frustration with tedious and expensive zeroing sessions led me to explore bore sighting options. Having wasted countless rounds trying to dial in new optics or after swapping scopes between rifles, I needed a more efficient method. The Sightmark Laser Bore Sights offered a seemingly simple solution, a faster path to accurate zeroing and I was eager to see if the product could deliver.

My first impression upon unboxing was a mix of curiosity and slight concern. The brass construction of most models (though the 12ga model is aluminum) felt reasonably solid, but the lightweight design did raise questions about long-term durability. Compared to more expensive magnetic bore sights, the Sightmark seemed a budget-friendly alternative, potentially sacrificing some precision for affordability. I chose the Sightmark over more expensive options hoping for a balance of convenience and adequate accuracy for initial zeroing.

While initially excited about the potential time-saving benefits, I also harbored some skepticism. The price point made me wonder about the laser’s quality and the overall consistency of the device, but a positive first trial would dissolve all doubt. Would it prove to be a valuable tool or just another gadget destined for the back of the safe?

Real-World Testing: Putting Sightmark Laser Bore Sights to the Test

First Use Experience

My first test of the Sightmark Laser Bore Sights took place at my local shooting range, a controlled environment perfect for assessing its initial accuracy. I tested the .223 Remington/5.56mm NATO model on my AR-15, aiming to quickly zero a newly mounted red dot optic. The process was straightforward: insert the bore sight into the chamber, close the action, and observe the laser dot on a target set at 25 yards.

The laser was clearly visible, even in the bright daylight of the outdoor range, allowing for easy adjustments to the red dot’s windage and elevation. Within minutes, I had the red dot aligned with the laser dot, a process that would have taken significantly longer using traditional live-fire methods. The initial setup process went smoothly, but the real test would be on the target downrange, with live ammunition.

Extended Use & Reliability

After several months of using various Sightmark Laser Bore Sights across multiple firearms, the initial convenience has largely held up, but some concerns have emerged. While the brass construction (or aluminum in the 12ga’s case) has proven reasonably durable, the battery caps on some models have shown signs of wear, especially on firearms with forceful ejection. The battery cap on my 12-gauge model took a beating from the action on my pump-action shotgun.

Cleaning is simple, requiring only a quick wipe down after use. Compared to the trial-and-error of pure live-fire zeroing, the Sightmark has consistently provided a quicker, less wasteful starting point. However, it’s become clear that the Sightmark Laser Bore Sights are best suited for getting close to zero, requiring further refinement with live ammunition.

Breaking Down the Features of Sightmark Laser Bore Sights

Specifications

The Sightmark Laser Bore Sights are available in a wide range of calibers, from .17 HMR to 12-gauge shotgun, catering to diverse firearms. Most models feature a brass body, while some, like the 12-gauge, utilize aluminum, offering a balance of durability and weight. Power is supplied by AG3 or AG5 batteries (depending on the model), providing sufficient energy for the laser projection.

The inclusion of batteries and a carrying case adds to the out-of-the-box usability. The brass construction (again, aluminum for some models) ensures reasonable resistance to wear and tear, while the caliber-specific design guarantees a snug fit in the chamber. These specifications translate to a user-friendly tool designed for convenience and compatibility across a variety of firearms.

Performance & Functionality

The primary function of the Sightmark Laser Bore Sights is to expedite the initial zeroing process, and in this regard, they perform adequately. The laser provides a clear reference point for aligning optics or iron sights, significantly reducing the number of rounds needed for preliminary adjustments. However, the laser’s visibility can be limited in bright sunlight, requiring shaded conditions or use at shorter distances.

A key strength is the time-saving aspect, allowing shooters to quickly establish a rough zero before fine-tuning with live ammunition. A notable weakness is the potential for slight misalignment, especially with models that have looser tolerances. The Sightmark Laser Bore Sights meet expectations as a convenient starting point, but they don’t replace the need for careful zeroing with live ammunition.

Design & Ergonomics

The Sightmark Laser Bore Sights are designed for simple, intuitive use. The caliber-specific chamber insert ensures a secure fit, and the battery installation is straightforward. The compact and lightweight design makes it easy to transport and store.

However, the battery cap design could be improved, as it can be prone to loosening or damage, especially on firearms with aggressive ejection patterns. The overall build quality is acceptable for the price point, but it doesn’t exude the robustness of higher-end bore sighting systems. The design prioritizes ease of use and portability, making it accessible to both novice and experienced shooters.

Durability & Maintenance

The durability of the Sightmark Laser Bore Sights is a mixed bag. While the brass or aluminum body provides reasonable resistance to impacts and wear, the battery compartment and laser diode are potential points of failure. The lifetime of the laser diode, especially in relation to continuous use, will vary.

Maintenance is minimal, primarily involving cleaning and battery replacement. With careful handling and storage, the Sightmark Laser Bore Sights can provide several years of use, though they are not designed for heavy-duty, professional applications. The Limited Lifetime Warranty offered by Sightmark adds a level of security and confidence in the product’s longevity.

Accessories and Customization Options

The Sightmark Laser Bore Sights come with a carrying case and batteries. They are not designed for extensive customization. Their primary function is as a standalone tool for initial zeroing.

While some users might consider aftermarket batteries for extended life, the core functionality remains unchanged. The Sightmark Laser Bore Sights are intended to be a simple, self-contained solution, focusing on ease of use rather than extensive modification. The accessories are limited, but adequate for the intended purpose.
