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

This is a great tool! It snaps right onto the muzzle on all my guns and the green laser is extremely bright and clear. I was concerned that it wouldn't be centered, but I co-witness it with iron or red dot sights and I've moved it all around the muzzle and it doesn't seem to change the dot point at all! The battery life isn't really a concern since it's rechargeable, but I only run it for a few minutes at a time anyway. Considering that it works for every caliber firearm I own, it's a terrific value and makes bore sighting red dots a breeze. I'm extremely please with it. Oh, and my cats love it too. 😂

Seemed to work exactly as advertised. Super simple. Rested on a sand bag barrel cradle and zeroed to it down the hall in my house. Went to range later in week and was just slightly off but close enough to finish tuning at range.

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.

Really helps sighting in new red dots. It gets it pretty close to center. Key is making sure the magnet is as close to center as possible and make sure you don't bump the magnet. Used it at about 50 feet in my garage before going to the range. Worked exactly like I had hoped it would.

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.

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 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
