MidTen Rechargeable Bore Sight Laser for .17-12GA, Red Laser Boresighter Kit with Multiple Adapters, Professional Bore Sight Kit with Upgraded Rechargeable Battery and Button Switch

I tried it on 9mm, 22LR and 12GA guns/rifles. Worked very good. But after 15-20 yards it is hard to see (red laser).

Super easy to use and accurate out of the box. Looks like a good quality kit and definitely worth the value.

Many other bore sighting tools are slightly off center, and you shouldn’t need to “zero” your zeroing tool. You can rotate a zeroing laser as you point it ant a target and it shouldn’t move. This one is PERFECT. If you have a lesser laser bore tool, you can rotate yours on target and you see a ring instead of a dot, you can zero toward the center of the ring, but you shouldn’t have to do that! With this tool it’s exactly on target. Can be used for any caliber. I considered getting the cool “bullet shaped” bore laser tool because they look cool and fit in your case easily. But you need a different one for every possible caliber and I couldn’t find one where people didn’t complain about it being off. And with those you can’t compensate by rotating the tool and using the center of the ring, because it’s inside the gun. So you can only use those to “get on paper” and then you have to manually zero it. If you’re not even on paper at first, move target a bit closer instead. Use this tool and your zeroed in two minutes. Period.

Works on any weapon thanks to the different sizes. it was a little inconsistent, the little screw to attach is very delicate and flimsy, I wish they could design that part tougher. There's no guarantee the laser is straight, as it has two adjustment screws for vertical and horizontal. It lined up with my iron sight well enough that i feel it is resourceful tool when mounting new optics. Overall value is better than going to the range, and it's rechargeable so you don't need to buy batteries, since all the other bore lasers use weird batteries I got this one.

Easy to use, works well.

I was impressed how easy it was to use. Watch a couple.Youtube videos beforehand and your all set...Being rechargable ROCKS

Item works great once you figure which attachment to use depending on what caliber weapon is being sighted. They aren't marked very well. But if you reach out to the seller ,they will respond promptly

Great boresight for the money, works perfect. I sighted in house at 12 feet with 2 dots sharpied on wall the same distance apart as my crosshairs and rifle bore then 2 clicks up, I'm hitting dead center 3/4" low at 25yrds which is perfect because I like to put the crosshairs right on top of they're heads and 25yrds is the max range I usually shoot vermin. Also being rechargeable is double great because I don't need to try and find odd sized batteries like my old boresighter.

Wasn't straight, had to return it
