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

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.

Easy to use, good quality, great price. Zeroed inside, only needed minor adjustment on the range which saved a lot of time. Also cannot beat all of the caliber adapters.

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

I don't know if I got one that was not calibrated but it is not even close. I like all the adapters, Lazer is bright but it ends there. I sighted in a.22 rifle at 20 yards then checked it at 50 yards and it looked great. Went to the range and set up a target at 50 yards and it was way high 12 inches too high . Maybe it will work after I adjust it. I didn't buy it to have to set it I am 100% sure the factory has the equipment to do it and actually sell a usable item. Ok I contacted customer service and they resolved the issue by sending me a replacement, they were prompt and easy to communicate with. I tried the replacement unit out and it is very good, got me to the bullseye first try and only took a few clicks to dial in at 50 yards.

Very happy with this purchase and has worked for sighting in every firearm I own.

The various adjustment pieces that come with it fit all my guns. I was able to fine tune two pistols, and did a site-in with a rifle and scope as well....saves a lot of range time and ammo and doesn't leave you guessing trying to find the center of a grouping. Nice case that has slide locks to keep it from accidentally opening and parts going everywhere.

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.

This works great and is really convenient for zeroing in but the calibers are different than what's advertised. A 5.56 requires a <5mm laser (5.5mm laser is too big) and same issues with my 6.5 Creedmore
