EZshoot Bore Sight 9mm Green Laser Boresighter with 12 Batteries

If you’re zeroing a red dot, these are definitely worth having. I checked to make sure the laser was properly centered before using it, and it was spot on, which gave me confidence during the zeroing process. It made getting on paper much quicker and saved both time and ammunition at the range. My only real complaint is the battery life—it doesn’t last very long, so I’d recommend keeping a few spare batteries in your range bag. Other than that, it’s an excellent tool and has worked exactly as expected.

I’ve had some bad experiences in the past using red laser ones but this one did a VERY good job as the laser was green making it visible to me adjusting my red micro dot Osight s. It made adjusting the o sight on top of my CZ P-09 Nocturne Compact very fast indoors. I took out my magazine and unloaded the chamber of my P09 nocturne compact.. I then took the laser casing batteries installed (laser on) and loaded it in through the ejector port and then seated it in the chamber. I racked it back 2-3x lightly to ensure the laser was seated where it needed to be… I then went to one edge of my house and pointed the laser in the cz towards the 20 yard wall in my living room. This then allowed me to adjust my micro dot so it was sitting on top of the green laser exiting the barrel. One way to really ensure it’s on top of the laser if it’s a different color than your optic reticle.. is to look through the optic at the laser point onto the wall.. while watching cover the barrel to stop the green laser while covering it and uncovering it to really see where the optic is in regards to the laser. Once it is close enough and on the optic reticle center … that’s the best you can do until you go to the range where I will make micro adjustments to the optic based on what my bench vice shots are doing on paper: I have no doubt it will be very close and need minor adjustments.

Makes quick work of sighting in a red-dot sight. The contrasting green is easy to distinguish from my red sight. (If I had a green sight, I’d buy the red laser instead). That way it’s not red on red, or green on green. I really like it. Makes the rough sight in very quick. I wish it had an on/off switch. It’s very bright! And went through 3 batteries in about 3 sessions at the range and 3 sessions pre-sighting at home. But they give you 12 batteries. Also, I wish there was a way to dry fire with it. It’s very tempting, but that would wreck it. Probably not good for the gun either. Gets into the barrel snugly. Not a bad idea to have a wood dowel or non marring item on hand to push it back out. But overall, the advantages really outweigh the disadvantages, and for the money, it’s well worth it. Good precision, and best group I’ve ever shot with my red dot out at 25 yards. Way more accurate than I am, lol.

For a quick gun barrel alignment, these laser bore sites are great. You can sight in your gun in a few minutes. Very easy to use. I think they are a great value.

Good item easy to use.

Excellent works great and very easy to use

Easy to load into the chamber (Glock 45 5th) (though may need to remove with wooden tool). Used it to calibrate my red spot targeting laser - highly accurate - easy to calibrate. The green laser easier to use when calibrating red laser. Easy instructions on inserting battery and using the boresighter.

Fit perfectly on the chamber on my Canik TP9 Elite SC, locked the slide back an inserted directly into the chamber to avoid damaging the extractor just in case but doing it like this won’t extract when you pull the slide back but nothing that you can fix using something like a pen insertion through the front of the barrel. I used it to zeroed a red dot and got me pretty close to it, about an inch lower at 25yds. The green color laser is easier to get your red dot zeroed rather than the red laser because it doesn’t get you confused.
