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 Zeroing

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.

Used to set up my 5.56. The green laser made it easy to site in the rifle. The whole operation took me less than 5 minutes. From setting up the laser with the correct tip to turning the sighting knobs to get the scope centered. I was leaving the range in less than 10 minutes with only five shots taken. That's how accurate this particular system seems to be. It's a great value for a great price and I'm glad I made the investment.

Top quality! Easy to use! It will get the job done! GREAT VALUE!

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.

Love this thing. Comes with all the attachments and accessories needed to sight in any caliber firearm scope or red dot. The laser is bright and crisp. Being green it helps get it zeroed in way tighter and more accurately with a red dot cause you have the contrasting colors. Batteries have lasted a long time without replacement needed in the last few months.

Good powerful laser. I use it to prepare and test align my optical gun sights (e.g. Holosun, etc.) inside my garage before I go out to the range. I also use it in interior ranges to align at further distances rifles. I have a green and a red which I use in contrast to the color of the gun sight. I put it in the barrel, then compare the barrel laser imprint with the sight on the weapon. If you use a green laser on a red dot, it shows up quite nicely and you can at your leisure the gun sight to the barrel before shooting anything. I only use 2-3 of the caliber adapters, but it's nice to know you can bore sight a lot of other calibers. Make sure you turn it off as soon as you're done with it because it will use up the battery very quickly.

This thing will save lots of time during sighting. Gets you on the paper without having to use hardly any ammo. Covers pretty much any caliber. Used it many times and it has saved lots of frustration and time.

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
