ANNCED 9MM Bore Sight Cal Laser Sight Red Dot Boresighter with Three Sets of Batteries (9MM)

This is a simple and easy to use device. Had my laser sighted in within minutes on my pistol. This bullet type is much better than the ones you insert from the front of the barrel (those tend to wobble and not be secure in the barrel. Not sure about the battery life but they do provide you with 3 sets.

My one and ONLY issue is that if the batteries are installed. The laser is on. There’s no off or standby. I did leave it on accidentally and a week later there was still a little laser beam emitted. Since you get 2 sets of those tiny watch batteries I’m happy to say it continues to be a useful and accurate tool in my arsenal.

Very simple to use, but don't load on magazine then try to chamber, they have to be hand inserted. Worked exactly for what I needed, they do get bigger at long distance and of course lighting will affect it as well. Overall very happy.

I was super disappointed to find that this arrives completely uncalibrated. On first use i thought my new pistol was 6 inches off but the laser was just completely loose and i have nothing small enough in my tools to adjust it so i have to go out and buy that.

Seems good. Comes with 6 batteries, uses 2. it is fine for sighting in. more useful at dusk or evening due to the small batteries and the light which gets dimmer by the minute. Worth the 10 bucks. It is intended just to sight things in, so, it serves its purpose.

Easy to install batteries, loads into camber like a normal round, ejects just as easily. Was able to use this laser to adjust a red dot sight in less than a minute. Great tool.

The only reason for buying a bore sight laser: To see where the barrel points.But this laser points to the side and cannot be corrected, so it is useless!!!

The picture tell it all. No matter what distance or how much cleaning of the lens, you get a blob. As best I could tell the laser was way off for accuracy.
