Frequently asked questions

Can I use this boresighter on a .308 bolt-action rifle?

Yes. The SM39005 chambers directly into .308 Winchester rifles. Simply insert it into the chamber, aim at a distant target, and align your scope's reticle to the laser dot.

Does the boresighter work indoors or only outdoors?

It works indoors in a darkened room at close range, though a 25-yard outdoor target gives clearest results. The laser is visible in low light but performs best in controlled darkness.

How long is the California firearm waiting period?

California requires a 10-day waiting period from when DROS is submitted until you can take possession of the firearm. Looking for gun store Cupertino? Visit us in Sunnyvale.
