MidTen Bore Sight Laser 9mm/223 5.56mm/30-06/25-06/270 Laser Bore Sighter Boresighter with Batteries

Very bright, easy to use. No on off switch tho, you have to remove the batteries. I used this to zero a red dot at 25 yards, the beam was bight enough that I could have gone much further. I rotated the boresighter in the chamber to recheck it and make sure it was truly centered and it was.

Handy tool for getting your rifle shots on paper, well made and easy to use.

Decent bore sight . Bright laser and easy to use. Got on paper real quick.

worked as I expected, Happy with it for the price.

Great tool for sighting in a pistol optic Berry easy to use and is pretty close to zero Great quality and inexpensive

This thing is spot on in a HK VP9. It allows for the chamber to close and fits firmly without getting stuck. As has been said before, it will not eject, and so you have to thunk it out or poke it out. The laser is quite powerful and easy to see. Great to sight in a green dot because of the contrast. Whether this is for you depends on your use case. If you do a lot of boresighting you will want something easier to use and with an on off switch. The batteries are teeny tiny and to keep having to remove them to turn it off is a great inconvenience. If you are only occasionally sighting in a Trijicon or other premium sight that is permanently mounted, this is a great value. Just carry a little baggie for the batteries and forget about it in your bag. But if you are going to use it a lot, its going to get annoying and you will drop and maybe lose the tiny batteries. I carry alot of these batteries so I put about 10 in my bag. So if you are sighting a rail mounted optic, you may want to consider something else. A little CLP on the outside and it will fall out of your chamber when you open it. About the lack of an on/off switch: I knew of this when I ordered it (apparently some of the other reviews did not read the description) and I was okay with it, that is until I actually had to keep doing it. But at 15 bucks, what the hell, it will be another toy that I don't need but may occasionally find a use for. I even sighted my sons nerf gun and mounted one of the 12 dollar red dots on it. As a note, I also purchased the Okeba 0.22 to 0.50 Caliber Cartridge Red Laser Boresighter. I was astonished at the quality and accuracy of it. They both confirmed each others accuracy. The Okeba is versatile and easy to use from a 22 Ruger Mark IV to a 1911. If you need the versatility or plan to do many boresightings, spend the extra 20 bucks. Or be me and buy both.

Great iron sights alignment tool and for setting up a red dot. no on or off switch, just pull out included batteries. works great!

Use in the air.. super sturdy and tight. Had a very long range for the red lazer.. helps keep the drive sight alignment perfect super easy to use and a killer value for the money.

Very bright works well to get you on the target

This will help get you on paper a lot faster/ cheaper than running a whole box of ammo through your rifle. Very happy! Only gripe is that you have to remove the batteries to turn it off.

Facile a utiliser, parcontre le laser n'éclaire pas bien par temps ensoleillé.

Best thing ever! No more wasting shells! I have one for every rifle I own

good accurate laser chambers and extracts easily makes quickscope setup
