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

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!

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.

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.

I've had several different kinds of laser bore sight devices. Ones that are the shape of a cartridges, that you put in the chamber. But those tend to be slightly off center. Every time you put them in the dot shifts noticeably. I've also had the type of laser bore sight tools where you have dozens of little plastic tips, that you have to change to match your barrel's inner diameter. Those work pretty well, but it's a little fidgety to change the tips if you have several different calibers to align. Not so much if you just have one or two. But still a little bit of a pain. The CVLife rechargeable laser bore sight tool is ultra simple. Place it on the end of your barrel, turn it on. Adjust your sights so they match where the laser is pointing, at the distance you want the zero set at. 25 yards, 50 yd, whatever you want. And you're done. I tested rotating the boresight tool to make sure it was pointing true, and it definitely seems to be. The laser didn't shift at all no matter how much I rotated the device. So I'm pretty sure this is properly calibrated right out of the box. Set up literally takes half of a second. Basically, once you put on the end of the barrel and turn on the laser, the setup is done. Best of all, it recharges with USB c like everything should. Which is absolutely wonderful. I'm giving this device five stars out of five because I can't give it ten stars.

I HAVE A DIFFERENT MODEL THAT GOES INTO THE BARREL FOR DIFFERENT CALIBERS. SOMETIMES IT'S NOT A GOOD FIT, AS THERE IS A SLIGHT WIGGLE. THE CVLIFE RECHARGEABLE ELIMINATES THE WIGGLE. THE MAGNET IS SUPER STRONG. THE GREEN/RED LASER BORE SIGHT MAGNETIC BORE SIGHT LASER FOR MULTIPLE CALIBERS IS FAST, ACCURATE, AND EASY. I'VE 13 RIFLES AND 9 HANDGUNS, AND THIS MAKES GETTING ON PAPER BOTH FAST AND SIMPLE. I PURCHASED ONE IN GREEN, AND WHEN I SAW HOW GREAT IT WORKED, I ORDERED ANOTHER IN RED.

I got the device and changed it to full. I used it a few times and wanted to charge it up to keep it in my range bag. Once the device was fully charged. I went to unplug it and got a bad shock from it. After that it would no longer charge. But another one if you need a bore sighter. This one is garbage and dangerous.

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

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

A simple and useful device but only good indoors or outdoors in dim light. Gets blown out within 10 feet when the sun is out. Claims of usability at 100m and 50m are not reproducible and in my experience completely false. The laser is simply not powerful enough for these distances in daylight
