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

Probably the easiest purchase I have done and love how it works. Super simple to use and makes it super easy to sight in your sights before going to the range. It was dead on for accuracy and fit perfect in my 9mm

Works like a charm. Sited my Glock 19 with Holosun red dot in a couple of minutes on a target I taped to the back door. Verified at range to be spot on. Just remember TWIO batteries are required.

I have this item in 9mm, 556, and .38/.357. They're all excellent. It come with enough batteries to last you years. Makes bore sighting a firearms quick and easy. They're a simple tool made well.

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.

Item works great, came fast and great price. Came with batteries. I found out that these lasers do not make your firearm accurate.

Super great product. the size is as if it was a round and fits in the chamber like a round should. the Laser was easy to see and alignment was so easy to do. the durability of this was very good, alot better than the some other i have had

Laser is strong and works great, used it to adjust my sight on my EDC, saves you ammo for just getting this for $12 I definitely recommend this instead of using up ammo lol

Cool little laser. Works good and comes with 4 extra batteries.
