Accurately zeroing your AR-15 is crucial for effective shooting. While traditional methods exist, using an AR-15 laser bore sighter offers a significant advantage in speed and precision, especially for beginners. This comprehensive guide will delve into everything you need to know about laser bore sighters, helping you choose the right one and master the zeroing process.
What is an AR-15 Laser Bore Sighter?
An AR-15 laser bore sighter is a device designed to quickly and accurately align your rifle's sights or scope with the barrel's bore. It utilizes a small, powerful laser that projects a visible beam through the barrel, indicating the point of impact at various distances. This eliminates the need for extensive range time and ammunition expenditure during the initial zeroing process. The laser's pinpoint accuracy allows for a much faster and more precise alignment compared to traditional methods.
Types of AR-15 Laser Bore Sighters:
There are two primary types of laser bore sighters available:
1. Battery-Powered Laser Bore Sighters:
These are the most common type, requiring batteries to power the laser. They offer the advantage of being relatively inexpensive and easily replaceable batteries. However, remember to check the battery life before each use.
2. Self-Powered (Kinetic) Laser Bore Sighters:
These operate without batteries. Instead, they use the firearm's recoil energy to power the laser. This eliminates the need for battery changes but generally commands a slightly higher price tag.
Key Features to Consider When Choosing an AR-15 Laser Bore Sighter:
Several features should influence your purchase decision:
- Laser Color: Red lasers are the most common and affordable, offering good visibility in daylight conditions. Green lasers, while more expensive, provide significantly better visibility, especially in bright sunlight.
- Power Source: Decide between battery-powered convenience or the self-powered, recoil-activated option.
- Durability: Look for a durable construction capable of withstanding the recoil of your AR-15.
- Adjustability: Some models offer adjustable intensity or focus, allowing for better customization.
- Compatibility: Ensure the bore sighter is compatible with your specific AR-15 caliber.
How to Use an AR-15 Laser Bore Sighter:
Using a laser bore sighter is straightforward:
- Safety First: Always ensure your firearm is unloaded and the safety is engaged.
- Insertion: Carefully insert the laser bore sighter into the chamber of your unloaded AR-15.
- Activation: Activate the laser according to the manufacturer's instructions.
- Alignment: Point your rifle at your target (a target at a known distance is ideal). Adjust your sights or scope until the laser point aligns with your intended point of impact.
- Verification: Once aligned, verify the alignment at different distances if possible, adjusting as needed.
Benefits of Using an AR-15 Laser Bore Sighter:
- Speed and Efficiency: Significantly reduces the time and ammunition needed for zeroing.
- Accuracy: Provides a more precise initial zero than traditional methods.
- Cost-Effective: Saves on ammunition costs in the long run.
- Convenience: Can be used in various locations, eliminating the need for a shooting range for initial sight alignment.
Maintaining Your AR-15 Laser Bore Sighter:
Proper maintenance will ensure the longevity of your laser bore sighter:
- Cleaning: After each use, gently clean the device to remove any debris.
- Storage: Store it in a safe, dry place to prevent damage.
- Battery Care (if applicable): Replace batteries when necessary to maintain optimal performance.
Conclusion:
An AR-15 laser bore sighter is an invaluable tool for any AR-15 owner, simplifying and enhancing the zeroing process. By carefully considering the features discussed above and following the instructions for use and maintenance, you can significantly improve the accuracy and efficiency of your shooting. Remember to always prioritize safety and handle firearms responsibly.
