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

Easy to use! Works great. Saves time and money I like the option of both red or green now. So you can choose the color opposite of your dot color optic to quickly zero in the dot I prefer running green dot optics, so I went with this red kit. Worked perfectly with my 9mm firearm Pros: -Quick and easy setup -Provides multiple tips for multiple sizes Cons: -Battery: 1 battery already died after just using one time for about 5min or so. Keep in mind the batteries are non-rechargeable -No battery life indicator to let you know how much power is remaining Will test at the range to see how accurate it is , now that it’s dialed in Overall, great value for the money so far. Will update review once I test at the range

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 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.

As someone who enjoys spending weekends at the range perfecting my aim, I was thrilled when I stumbled upon this laser bore sight kit. With 32 adapters included, it feels like I’ve found the Swiss Army knife of bore sighting. The range of calibers it covers is impressive, from the smallest .17 to the hefty 12GA. This is a dream come true for those of us who have an assortment of firearms and want a one-stop solution for all our zeroing needs. One of the standout features is the laser’s visibility and precision. The option to choose between a red or green laser is a thoughtful touch, especially since the green laser offers superior visibility over longer distances. I’ve found that zeroing in on my target at up to 100 yards has become a much more efficient process. The laser’s accuracy is quite remarkable, saving me both time and ammunition, which, let’s face it, is a big deal in today’s market. The battery life is another highlight that deserves a mention. With two high-capacity batteries included, I can spend a full day at the range without worrying about losing power. The convenience of the button switch is also noteworthy, allowing for quick and easy operation without fumbling around. Plus, the arbor accessory ensures a snug fit for larger calibers, providing added stability and confidence when sighting in. Overall, this bore sight kit has transformed my shooting sessions into more productive and enjoyable experiences. It’s the little things, like the clearly numbered adapters and the thoughtful inclusion of accessories, that make a significant difference. Whether you’re a seasoned shooter or just starting out, this kit offers precision and reliability that’s hard to beat.

Works super well in low light. I was able to see the laser after sunset as far as my eye could see. I used my 1-6x scope and could see it on paper at 200+ yards. Does not work well during the day if you’re outside and that’s why I’m giving it 4 stars. It will work well at indoor ranges that don’t have a bunch of bright light. And work incredible in low light to darkness. I sighted my rifle in at night. I went in my backyard and used a range finder for a known distance and then turned my scope on and zeroed it. Shoots as straight as an arrow. I have a SA M1a socom 16 cqb chambered in .308 so it’s a 2-3moa gun so my grouping are still within that range at 100. Worked great!
