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

The bore sight laser, designed in a compact casing size, is a practical tool for initial firearm setup. While not perfectly precise, it reliably gets your sights approximately 90% aligned, minimizing the time, effort, and ammunition needed for final zeroing adjustments. It has proven effective across multiple calibers, including 5.56 and .300 Blackout, making it a convenient and cost-saving accessory for shooters. Throw one in your collection of tools, comes with batteries and a neat little case.

Works great, bought this to sight in my pistol and discovered my sights are not adjustable, and this laser lined up perfect with the factory sight alignment. Good value. Dead simple to use. Very bright laser. Take the batteries out when not in use.

Works very well, comes with 3 sets of batteries so that's nice. A laser bore sighter is a quick way to get red dot sights roughly zeroed without having to get to the range right away. Of course you need to actually shoot the gun to be properly sighted, but this gets you well within the ballpark and should save some ammo during the sight-in process. Comes in a nice compact case, easy to use, quick to install.

Pros: Works great, brightness is perfect and allows you to zero your rifle very quickly and accurately. Fit perfectly in both my .308 and my wife's .243 win rifle.Cons: Putting the batteries in was the worst part. Don't put them in one at a time because they flip by themselves. Do a stacking method and slide them in. That was the only way they got in right. Even that was difficult.It lacks an on/off switch so once you're done zeroing your rifle you have to remove the batteries to turn it off.Otherwise a great product for the price.

I purchased a laser sighter a while back that’s long and has multiple fitting for multiple calibers. It worked well but I found it was too long for a 3.5” barrel or shorter.So when I got a nice pocket sized conceal carry pistol the end of my sighter exceeded the barrel length. It was useless for a small pistol.Found these and it works perfectly. Great idea to just chamber the pointer. No worry it’s not snug or misaligned when it fits right in the barrel.Worked well. I’ve used it to confirm on two other pistols I had used the larger product on previously.Only downside is having to buy one for every caliber you own but that’s ok. Most people are 9mm or anyway.Oh and it can be tricky to remove so have something to push it out if needed. I found a good thump into my palm did work but it won’t just pop out.

Nice laser sight. Works great and very easy to use.

Works well, helped ro sight in my armalaser definitely recommend also come with 2 extra sets of batteries and a nice case to keep it in

Works great an super affordable. Only took me a few minutes to sight in my gun! Even came with 3 batteries!
