10 Best Bore Sight For 300 Black Out 2025 in the United States

The EOTECH XPS2-300 Holographic Weapon Sight is specifically designed for firearms using the .300 Blackout caliber, making it a suitable choice for both hunting and sport shooting. One of its standout features is the ballistic drop reticle, which allows users to easily zero in on both subsonic and supersonic rounds using the same reticle pattern. This can significantly enhance shooting accuracy without the need for constant adjustments. Its compact design is another plus, as it frees up valuable rail space for additional accessories like rear iron sights or magnifiers.

In terms of durability, the XPS2-300 is made from aluminum, which provides a sturdy build while keeping the weight to just 9 ounces. This lightweight design is beneficial for extended use without fatigue. Plus, it comes with a 10-year limited warranty, showing EOTECH's confidence in their product's longevity.

There are some considerations to keep in mind. Firstly, it lacks night vision capabilities, which may limit its use in low-light conditions for some users. Additionally, while the holographic sight is easy to use, the learning curve may be slightly steep for beginners who are not familiar with reticle systems. If you are primarily focused on utilizing the .300 Blackout caliber and want a sight that balances compactness with functionality, the EOTECH XPS2-300 is definitely worth considering. Just ensure that its limitations align with your specific shooting needs.

The design includes an arbor accessory for stable fitting at the muzzle, improving accuracy during zeroing and helping both beginners and experienced shooters achieve consistent results. The aluminum build adds durability while keeping the device lightweight.

The kit may feel a bit complex initially due to the large number of adapters and the need to select the right one carefully, though clear instructions are provided. It lacks night vision capability, so it’s best used in daylight or well-lit conditions. While it is a well-made product, it may be priced higher than simpler bore sights. This bore sight is a solid choice for someone looking for a professional-level and rechargeable laser tool compatible with a wide range of calibers, including 300 Blackout, combining accuracy, long battery life, and solid build quality with a minor learning curve for adapter selection.

The EZshoot Laser Bore Sight for 300 Blackout (7.62x35mm) is a well-constructed tool that aims to improve the accuracy of your shooting setup. Its high-precision red laser performs effectively in dimly lit environments, making it easier to zero in on your target from a range of 15 to 100 yards.

Additionally, it comes with two sets of LR41 batteries, allowing for around 3 hours of sighting time, which is a practical feature for extended use.

The battery life of 1.5 hours per set may not be sufficient for longer shooting sessions, especially if you are using it extensively. Also, while the red laser is visible in many conditions, it may not perform as well in bright daylight compared to green lasers. This bore sight is ideal for casual shooters and hunters looking for a straightforward, effective way to improve their shooting accuracy without extensive setup.
