Rifle Laser Beam BoreSighter kit with Button Switch Multiple Caliber Adjustment .22 to .50 Caliber

The little adapters for various bore diametersAre junk they break if you look at them too hard. I don't recommend this unit unless you need it to get a overweight cat to run around the house

It works once you put new batteries in it. Not a quality product. I guess you get what you pay for.

Hard to tell How to install batteries Also push button switch not rotary

After struggling with this laser for months to get it to work with the ridiculous battery holder and bent contact spring, I finally got it to work, but tenuously. If the battery holder was joussled just a bit the laser would stop working. I arranged to return it but, alas, I waited too long to box it up and go aback to UPS.Today I turned it on, just out of curiousity to see if it would work. Switching it on, A BATTERY EXPLODED. The battery carrier jumped out of the laser and the exploding battery hit me in the chest. I have photos of the exploded battery.I know that Amazon sells a lot of Chinese garbage and much of it is not regulated by consumer safety laws. DO NOT BUY THIS or any of the clones that go by different names, sold by Chinese Amazon vendors.

Simple and easy to use. Well worth the money.

Would NOT purchase again

At first everything looked good came packaged nice then when unboxed not so much I bought to help a friend and son sight in there first rifle. But after reading and putting together I couldn’t get rifle sighted with them. Decided to check laser on my hunting rifle a weatherby 300 weatherby magnum I just had sighted. Lazer was way off what zero supposed to be.

Absolutely junk. Instructions say battery compartment should be installed and in the on position. The compartment is out with batteries loose. The parts DO NOT FIT Back together.Unusable and by the time I needed it it was after the return date.
