Finding the perfect zero for your .17 caliber rifle is crucial for accuracy and responsible shooting. While traditional methods exist, using a laser bore sighter offers speed, convenience, and improved precision. This guide explores the specifics of laser bore sighters for .17 caliber firearms, helping you choose the right tool and master its use.
Understanding Laser Bore Sighters
Laser bore sighters are devices designed to project a laser beam through the barrel of a firearm, allowing shooters to quickly align their sights or scope without expending ammunition. They’re particularly useful for initial sight-in, verifying zero after cleaning, or even troubleshooting sighting issues. For a .17 caliber rifle, the small bore diameter necessitates a laser bore sighter with a precise and appropriately sized emitter.
How They Work
A laser bore sighter typically consists of a laser emitter housed within a durable casing. This casing is designed to fit snugly within the barrel's chamber, ensuring the laser beam accurately reflects the barrel's trajectory. By activating the laser and observing the point of impact at a target at a known distance, you can adjust your scope or iron sights accordingly.
Choosing a .17 Caliber Laser Bore Sighter
Selecting the correct laser bore sighter is paramount. Incorrect sizing can damage your firearm or lead to inaccurate readings. Here’s what to look for:
Caliber Compatibility:
Absolutely crucial: Ensure the bore sighter explicitly states compatibility with .17 caliber firearms. Using an incorrectly sized bore sighter can damage your rifle's barrel.
Laser Power and Visibility:
A bright, clearly visible laser is essential, especially in bright daylight conditions. Look for specifications indicating the laser's power and wavelength (typically red or green; green lasers are often preferred for better visibility).
Durability and Construction:
The bore sighter should be made from robust materials to withstand the stresses of insertion and use. A durable design will ensure longevity and accuracy.
Features and Accessories:
Some laser bore sighters include additional features like adjustable brightness, different tip sizes for various calibers (although purchasing a dedicated .17 caliber sighter is recommended), and carrying cases for storage and protection.
Using a Laser Bore Sighter for .17 Caliber Rifles
Proper use is key to achieving accurate results. Follow these steps:
-
Safety First: Always treat firearms as if they are loaded. Ensure the firearm is unloaded, the safety is engaged, and the action is open.
-
Insert the Bore Sighter: Carefully insert the laser bore sighter into the chamber of your .17 caliber rifle. Ensure it sits firmly and securely.
-
Target Setup: Position a target at a safe distance (e.g., 25 yards). Make sure the target is clearly visible.
-
Activate the Laser: Turn on the laser bore sighter.
-
Sight Alignment: Look through your scope or align your iron sights with the laser point on the target.
-
Adjustments: Make necessary adjustments to your sights or scope until the laser impacts the desired point of aim on the target.
-
Verification: Once adjustments are complete, carefully remove the laser bore sighter. Verify the zero using live ammunition at the range.
Maintenance and Storage
Proper maintenance will extend the life of your laser bore sighter. Keep it clean and dry, storing it in its case when not in use. Avoid dropping or subjecting it to excessive impact.
Conclusion
A laser bore sighter offers a quick and convenient way to zero your .17 caliber rifle, saving time and ammunition. By carefully selecting a compatible and high-quality device and following the proper procedures, you can significantly improve your accuracy and shooting experience. Remember always to prioritize safety when handling firearms.
