Frequently Asked Questions

What is the 'one-shot zero' method?

The 'one-shot zero' is a technique that uses manual boresighting to align your rifle's scope with the bore before firing. This drastically reduces the number of shots needed to get your rifle sighted in, often achieving a zero in just two to five shots.

How do you perform manual boresighting?

To manually boresight, remove the bolt or rear takedown pin to look directly down the rifle's bore. Align the bore's circle with your target at a set distance, typically 50 yards, and then adjust your scope's reticle to match that alignment.

Can this boresighting method be used on any rifle?

Yes, the manual boresighting method is applicable to various rifle platforms, including lever-action rifles like the Marlin 336, bolt-action precision rifles such as the Ruger American, and AR-15 style rifles.

Is manual boresighting better than using a laser bore sighter?

Manual boresighting is often considered more reliable because laser bore sighters can vary in quality and accuracy. Looking through the bore is a proven, cost-effective method for most accessible rifle breeches.
