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

Very nicely machined and finished. Comes in a "mini Altoid" type tin with fitted foam and 3 pairs of LR41 watch cells (unit takes 2 to activate). Got my POI within an inch of POA on paper at 15 yards before firing the first shot with 3 different launchers; paid for itself on the first use. I'm sure it'll get passed around a lot since my buddies (like me) are switching to red/green dot sights as our eyes age and front sight posts get fuzzier over time.Also, it can be useful in demonstrating how proper grip reduces or eliminates that "low and left" phenomenon when coaching untrained shooters, if you have a third person to shoot video of a target on a basement or garage wall while the trainee's dot dances around on it.After final precise zeroing with live fire, I taped a note card with a 1/4" dot in the middle of it on one of my basement doors, leaned my back against the opposing wall, and aimed the pistol's dot at it with this boresighter in the chamber; I had a helper make a small circle around the laser dot on the card. Next time I have to remove the optic to replace its battery or deep clean the slide, I now have an offset reference to get back to a good zero without live fire. (Good enough for a compact or subcompact defensive pistol, at least.)I've paid more in the past for multi-caliber boresighters, but since compact 9mm pistols are so common nowadays, it makes sense at the ten dollar mark to just keep this in my range bag.

This thing gets the job done. Is it going to get you dead-on target right away? No. But it will get you close enough that only a couple of clicks are needed to be on center. I used it to sight in my green dot, irons, and laser—all off this one bore sight. After that, it only took me a couple of rounds to fine-tune everything. Measure twice, cut once.I did a 36-yard zero for my green dot and irons (following Shaun Ryan’s zero from his site), and the bore sight’s laser was strong and visible at 25 yards at an indoor range.Battery life could be better. You’ll probably get around 10 minutes of continuous use before the beam starts to dim. Thankfully, they include an extra set of batteries. I was able to sight all three optics, but when I went back to recheck, the laser had already started to fade.For $10, this is a no-brainer. It saves ammo, gets you on paper quickly, and makes the final adjustments easy. Again—gets the job done.

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 great However may be a slight issue getting out of the chamber on subguns like thecz scorpion or the stribog

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.

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

This one of my best purchases. I was impressed with the quality and price

This is a valuable tool to align the target!
