Sightmark Accudot Boresight .45 ACP Red Laser Brass

The Sightmark Accudot Boresighter is a chamber-loaded .45 ACP sighting tool that lets you confirm pistol alignment without live rounds on the bench. Built around a precision-machined brass body sized specifically for the .45 ACP chamber, the boresighter seats cleanly in the bore and projects a steady red laser dot downrange so you can adjust iron sights or zero an optic with far fewer trips to the firing line.

Powered by three AG3 batteries, the unit delivers a visible red laser at a 632-650 nm wavelength and less than 5 mW output, providing a fast reference point at typical indoor and outdoor sight-in distances. The solid brass construction keeps the tool durable for range-bag use, and it doubles as a handy training aid for dry-fire and quick-draw drills when you want to confirm sight picture before stepping up to live fire.

This SM39017 boresighter ships ready to use and includes both the carrying case and the AG3 battery pack so you can start sighting in your .45 pistol right out of the box.
