Frequently Asked Questions

What is the 'one-shot zero' method for firearms?

The 'one-shot zero' is an efficient boresighting technique that aligns the firearm's scope with the barrel's bore before live fire. This method aims to get the firearm on paper and zeroed with minimal shots, often just one or two, saving time and ammunition.

How do you perform manual boresighting on a rifle?

Manual boresighting involves removing the bolt or rear takedown pin to look through the bore. Align the bore with the target at a set distance (e.g., 50 yards), then adjust the scope's reticle to match the bore's alignment. Fire a shot to confirm and fine-tune.

Why is manual boresighting preferred over laser bore sighters?

Manual boresighting, by looking through the bore, is considered the most reliable method for many rifles where the breech is accessible. Laser bore sighters can vary in quality and accuracy, making them less consistently dependable than the direct visual alignment method.

What rifles were used to demonstrate the one-shot zero technique?

The video demonstrates the one-shot zero technique on a Marlin 336 in .35 Remington, a Ruger American Precision Build in 6.5 Creedmoor, and a custom AR-15 build chambered in 5.56 NATO / .223 Remington.
