If you spend 30 seconds making sure the rifle's chamber is clean, and that this seats fully, this gives a perfect shot down a bore. I set mine at dusk, and could see the dot about 200 yards away. Made it easy to see the angle of the rifle to scope, by checking at different ranges. Was able to get my first shot within a few inches very easy using this.

If You plan to set up optics on any weapon, get one of these that matches. The short battery life others have noted really doesn't matter much, as this is a tool that You should really only need to use when replacing optics on a rifle. A fresh set of batteries cost less than the 10 to 20 shots in ammunition it saves. Wouldn't be a bad idea to get an extra set and keep it on hand if You like to tinker with your setup a lot. It tested very "repeatable" for me, being that I could slide it in and out of the chamber repeatedly but once the bolt was closed it was always back to the same spot. If there is inaccuracy there, it is small enough to be insignificant for the purpose of this tool.

I put a small piece of paper in between the last cell and the one in front of it to turn mine off. This way I could crank it down tight, not worry about killing my batteries or loosing them.


To the reviewer who said it fit loose in his chamber, PLEASE be careful. You may want to get a set of go/no-go gauges or visit a gunsmith who has some and check Your rifle. Usually a loose fit is a sign of a highly worn barrel and may be unsafe.

THE PRODUCT WORKS GREAT BUT THE BATTERIES WHERE 95% DEAD. LASTED ABOUT 3 MINUTES BEFORE I HAD TO BUY NEW. VERY GOOD FOR 100 + YARDS. BEAM IS VERY BRIGHT. CARTRIDGE BORE SIGHTERS ARE THE BEST. ALSO WORKED GREAT FOR 30 06 CAL

Why 3 stars? im going to chalk it up to user error.

I keep asking myself HOW could this be so off? i mean the laser goes right down the barrel but it wasnt even close to on target. maybe it was user error who knows. But anyway, the batteries last a mighty 15 min so that stinks. Do yourself a favor and get a 20 dollar one that will work better. final thought, dont slam your bolt forward. got mine jammed with this thing inside.
