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 got this to try & zero my optic, was unsure if it worked well but notice it is very close compared to zeroing at the range. I purchased another type of these that cost more and is not a small cartridge and was pretty disappointed. I wasn't sure if this would be any good but not very expensive and works better than other ones I've tried. Easy to use and my cat enjoys it as 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.

Worked good, wish it had a switch you have to take battery out to turn it off but only going to use it a couple times a year . The extractor doesn't pull it out so you have poke it to get it back out. Worth the price though

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

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.

Super fast way to sight in my optics. Tested everything today and it’s all sighted in perfect
