CVLIFE Rechargeable Green/Red Laser Bore Sight Magnetic Bore Sight Laser for Multiple Calibers Professional Boresighter with Magnetic Connection

I purchased this for my husband for deer season this year. He really appreciated the convenience of it charging with a UBS, no batteries to replace or to worry about proper disposal. He reported it worked accurately and he was able to site in his new gun easily.

Works exactly as it should. (Green) Laser is clear and well focus. Clearly visible at 50 yds on a bright day. Easy to recharge and the on off button is easy to depress. My only negative would be that I wish the magnet was a little stronger but I haven't had any problems with it falling off.

I've used it to adjust a red dot and a few lasers. I had a different laser bore sighter that would fit in the barrel, it had issues because it did not fit snug and some barrels were to short. I like this one because it is magnetic and attaches to any barrel no matter the length

Pros: Seems to work as advertised. It is smaller than I expected. Magnet is strong. Concentric circles allow for proper alignment. Inexpensive Lightweight Cons: The green laser cannot be seen in day light. I have the original device in green laser that this device is copied from. It is larger and has a stronger laser. However, this green laser works better for pistols.

This device has saved me so much money in ammunition. The green is easy to pick up from a distance. I like that it's rechargeable. The charge lasts a really long time too! My brother bought one after using mine.

Yes, it's magnetic. But, no, it doesn't help. You can't get it to center on the end of a rifle barrel... there is just way too much variation to aid in sighting in. There is no one specific band of magnetism to mate up with the cage squarely. There is too much wiggle room. Every time you attach it, you're looking at a different POA. Do not buy if you are trying to do what I was. It won't work.

Great product! This is much better than getting a bore sighter with the different attachments. With the rings on the magnet side, you can easily center this with the bore of your gun. Accuracy seems right on. Visibility and brightness are great for use during the day. Extremely easy to turn on, center and zero your laser or red dot. Excellent product! Would highly recommend!

Works great use this daily at work to aim a large hydraulic cylinder before pushing on an item. Love that there is no battery to keep up with.

This is the 2nd one I have purchased for a Christmas present, and these laser bore sights are absolutely fantastic.
