EZshoot Bore Sight Laser 9mm/223 5.56mm/243 308/12-Gauge Red Laser Boresighter with Portable Tin Case and Extra Batteries

Worked right out of box. Had no issues. I range tested and it was right on. Don’t listen to bad reviewers, use common sense and you’ll have no issues. If needed I’d definitely buy you again. Great price, you won’t believe how good the quality is.

Really simple and easy to use. It also comes with two sets of batteries. Feels like a well made product.

Works good. I had one firearm that i knew was zeroed and another that needed to be. It fit perfectly and confirmed zero. Coming with extra batteries is a plus as well. Will buy one for my 556 next.

I used this bore sight laser for my 9mm pistol and it worked great. It came perfectly lined up with my barrel and I was able to sight my optics in very fast and easily (after confirming the laser's accuracy by testing it on a already sighted in pistol). It has a bright laser that is easily visible. It comes in a metal can with multiple batteries included which is pretty nice, but you probably will never use all of them, since they last a long time and the boresighter will only be used for a few minutes at a time. You can always save them for other appliances though. The reason this got a 4 star from me was the installation of the batteries. For a younger individual like myself, I found it slightly tricky the first few attempts getting the battery lined up and screwed in since it was so small. I think for an older individual, or someone with shakier hands, it would be a bit more challenging to get the batteries in. However, the functionality of this boresighter was great and I do recommend this if you want to sight an optic in without shooting live ammo or going to the range.

I got this for my S&W Shield Plus. As soon as you put the batteries in, the light comes on and stays on. I pulled the slide back and this dropped right in with no problem. I pointed at a wall about 20 feet away and it works great to check my sights. It did not pop out easily. However, I took a small dowel and put it down the barrel and it came right out. So it fits in the barrel snug and comes out easily. I does not say that it will fit in my 38 Special but it will go it part way and works for it too. This works better than a laser bore sight that has a button switch. This works great. I do recommend it. Be sure to take the batteries out before you put it away in the nice case.

EZshoot 9mm round laser calibration tool is exactly what I needed to cite in my green laser attached to my 9 mm. Price was very affordable and was delivered on time. Remember when you cite in any lasers be at least 21 to 30 ft away if you're using it for self-defense only. Targes may be different. Be very careful and make sure your weapon is literally unloaded and take extreme caution when doing so. This is not a toy but actually a device for calibrating optic sights or Lazer pointers that are installed. With that said check out the pictures. This thing is very bright and works very well. Only disappoint is the casing itself says use three batteries and three batteries will not fit only two batteries with that said, they have three sets of two batteries. There is no on and off switch so as soon as you install the batteries the light will come on. When you are done just unscrew and take the batteries out and put it back in its hard case that is included.

Works great. Makes sighting my pistols a breeze.

Super easy to use and had my sights on point. Used this to zero in 2 new sights I purchased. Went to the range and didn’t have to make any adjustments for a 10 and 15 years shot. Good strong laser. Only complaint is that you have to remove the battery to shut it off.
