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

If you follow instructions in video, it works very well. Tested against known to be accurate gun sight, laser lined up perfectly as expected. For the price this is really good purchase. Only down site is the adapters are a bit difficult to read, and the smaller calibers are unmarked so you need to test a few to find best fit. Like in the video, you pick the adapter that's close, then adjust by loosening / tightening the adapter while in the barrel. Creates a very tight fit and perfectly centered. Tend to believe the poor reviews were due to not screwing in the adapter while in the barrel. I now see the rechargeable item, that one looks better as the adapters are different colors. However this sight was available for next day delivery, the rechargeable was to be delivered in a few days. Needed something now. Very good purchase

Item worked with no flaws. Helped me out a lot with my Glock 19. No need to go to the target practice to adjust, now I can just go shoot and have fun. Great pricing as well. Would recommend to anyone who needs it. Works for all guns as well, used it on my 5.56 sig sauer and has the adapter for that as well. 10/10 good product.

This bore sight kit made sighting in my rifles much faster and saved me time and ammunition at the range. The laser is bright, the adapters fit securely, and the kit is well organized in a sturdy case. It was simple to set up, and everything needed was included. Accuracy was excellent for getting on paper before making final adjustments. Great quality for the price, and I would definitely recommend it to anyone who owns multiple firearms.

Great tool. I used it to help zero some red dots on some pistols. It worked well and I got really close at home and fine-tuned at range.

Nice set. Many adapters, easy to use. Green laser is easy to see & great for outdoors.

This is a quality kit well put together and will make zeroing in a lot easier without falling apart

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.

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.
