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

Received the other day, seems well made, laser is bright but haven't got to the range to try verify accuracy. Works in most of my barrels but doesn't work with my micro 9 with a 3.1 barrel, back part of unit sits in round chamber and cannot lock up in barrel. This doesn't bother me but shorting unit by 1/2 inch would fix this issue, though I don't know if this would affect accuracy in longer barrels.

This laser bore sight worked great. I only had 60 yards to work with, but I was able to see the laser from 60 yards away. I aligned my optic to the laser and went to the range. First shot at 100 yards was on the paper, and it was only 4 inches low and 3 inches left. This product does what it's intended to do and gets you on paper.

Easy and accuratebore sighting tool.

Seems to work very well so far. I sighted my pistols and rifles and it was easy and pretty on point. Seems to be a very decent bore sight kit.

I have now used this several times on multiple pistols and I am pretty happy with it. It is consistent, fairly true (rotating it in the barrel does not change the dot's location) and would seem to work as desired based on what I am seeing at the range. It is fairly inexpensive so weak QA may be why some have not had as good as an experience, but that is just a guess. I think you do need to be a little careful about how you fit it to the caliber you are using. I take the largest insert that will fit in the barrel and just loosely screw it onto the bore sight, slide it as far is it will go into the barrel and then rotate the bore sight clockwise to tighten it up and fit snugly against the barrel crown. Your mileage may vary, but I have no complaints with it.

The CVLIFE Professional Laser Bore Sight Kit is an outstanding tool for anyone who needs to quickly and accurately sight in their firearm. The kit includes 32 adapters, which means it fits a wide range of calibers, from 0.17 all the way up to 12GA, making it versatile for various guns. I was able to easily find the right adapter for my rifle and quickly get the laser positioned in the bore. The laser itself is bright and easy to see, even in daylight, and the adjustment controls are simple to use, allowing for precise alignment without the hassle of traditional sighting methods.What I really appreciate about this kit is how much time it saves. I was able to get my scope dialed in much faster than I would with a regular range session, and it saved me ammo in the process. The build quality of the bore sight is solid, and the kit comes with a nice carrying case for storage and transport, keeping everything organized and protected. Whether you're a seasoned shooter or just starting out, the CVLIFE Laser Bore Sight Kit is a must-have for making your sighting process more efficient and accurate. Highly recommended!

The product works excellently; I was able to calibrate the sights on all my firearms without any issues. This kit is very complete.

Product comes with multiple caliber adapters as described. Easy to use. Will definitely save money on number of rounds needed to zero your platform.
