The Chamber Laser Boresight gets you on target quickly without wasting a single round. Simply drop the boresight into your chamber like a standard cartridge, and the bright 632-650nm red laser will show you exactly where your rifle is aiming. When done, it ejects just like an empty casing, clearing your chamber allowing you to go straight to live fire, without the risks of forgetting a bore-mounted sight.

This thing worked great. sighted in my ARs at 25 yards in my back yard in about 10 minutes. very small and crisp at about 25 yards unlike other bore sights I've seen.

Great Toll to have in your range bag
