CVLIFE Professional Laser Bore Sight Kit with 32 Adapters fit 0.17 to 12GA Calibers, Red or Green Bright Bore Sighter Laser with Button Switch, Powerful Support for Hunting

I've been wanting to buy a kit like this for years but never could find one I thought was made well... I finally pulled the trigger on this one (no pun intended) to sight in my new .308. I was quite impressed with how bright the laser is and how easy it was to use. I was a little skeptical that it would work well but to my surprise it's pretty good quality and seems to function really well. It also came with 2 batteries which is nice because it only uses 1... Make sure not to discard the paper that comes with it as it contains a chart to show which barrel adapter you'll need to use for the caliber you are working with.

I’ve used once but it worked perfectly and very easy. Used it on the range and worked great. The sighting was perfect. I bought the green laser and you can see in bright sun. Use the correct alignment adapter and it fits perfect. There are 2 batteries included so battery life isn’t an issue

Better than you would expect at the price point. The case is a little flimsy, but the laser itself feels very sturdy. It’s bright and I have no trouble seeing it through my optics. The adapters feel a little fragile, so I wouldn’t over-torque anything as you’re installing them. Overall a pretty good set. Sighted 3 weapons and they were all shooting good groups when I put them on paper. Also, it ships with 2 batteries to keep you going for a while.

I wasn't sure I'd keep it when I ordered it, but I'm definitely keeping it. It was so simple to use. Loaded the #10 adapter (for my 9mm) on in seconds, slid it all the way in and when tightened it didn't even jiggle at all. Zeroed in at 25 yards with a very minor adjustment needed after live fire. It comes with more tips and tools than I need for now, as well as 2 batteries. I have previously paid $30+ to have optics zeroed in. I barely paid that much for this entire kit. We'll worth the price.

This later bore sight worked great on setting up sights on a lot different size guns must have. For easy set up.

Exactly what I was looking for and less expensive than the ones I saw on facebook. The green laser is bright and will travel a long distance. I even tried rotating the laser in the bore to see if the alignment changed and it held true. I haven’t gotten to confirm it on paper yet, but I’m confident that most of my adjustment will be for bullet trajectory.

i tried 9mm and .40 cal bullet style bore sighters and the 9mm worked great but the .40 didn't fit my gun for some reason so it pointed incorrectly. this kit fit both 9mm and .40, and i tried it on my 22lr worked great. i like that when you rotate it in the barrel you can see it's still pretty damn straight, also the case holds everything together nice and it comes with an extra battery. hope this thing holds up it's a nice little kit.

The good: The tool works very well and the laser is quite bright which is pretty good. This is also far more affordable than other versions out there on the internet. The bad: the fit is absolutely terrible. Every adapter and its label is wrong and likely too large. I matched up 12 guage adapter to my 12 guage and it was far too large and wouldn't go in my barrel. I wasted a lot of time just grabbing each size adapter then switching to the next. The battery provided was junk. It worked for 5 minutes of use then was immediately dead brand new out of the package. I would honestly recommend a different tool set that has accurate adapters.
