Feyachi Green Bore Sight 9mm/223 5.56mm/12 Gauge Bore Sight Laser Boresighter with 3 Sets of Batteries

Works great in my ACI 15

Very good bore sight. Green is very easy to see, more so than a red dot. Sighted in at 50 yards. Put me very close to bullseye. Great tool to get close, then make few adjustments as this will get you close. Love the tool, use once a month. Will buy again, will recommend, fast shipping.

Great quality and accuracy

Install the batteries and its 'on'. No way to turn it off except to remove battery. Over-priced for what you get.

Seriously folks, I am a believer in "paying it forward", so when I purchase a product that exceeds my expectations, I will go out of my way to let the world know. This is how as consumers we reward the manufacturers. The opposite is also true. This laser Bore Sight was literally Spot On collimated and axially aligned to its housing, thus, rendering a super precise (centered) laser beam. I checked it by clocking it within my bore in 12 locations - no deviation whatsoever - impressive for the price. Even if it were to be off, there are intuitive methods to compensate for that. Such a method is to "clock" or make incremental marks where the laser goes as you incrementally rotate the laser clockwise (use at least 8 points). When done, your exact point of interest to base your sighting will be the center of those incremental marks. Use a pen/marker to kee track. Just make sure your firearm does not move during this process. I did not have to do this as mine was literally perfect at 75 feet.

I ordered this and tried it, seemed to work but once I zeroed my sight in and moved my Sig P365 XMacro and looked again it moved. I then realized that the 9mm laser bore ever so slightly moves in the barrel once I closed my slide to sight in the laser. I have a Holosun SCS optics on my Sig so I was trying to zero it in. I then bought another one because I thought it was a one off production problem but yet again the same problem. I purchased another brand green laser bore sight and its solid and theres no movement and now I can truly get my sight optics zeroed in. It’s too bad, it seemed to get good reviews, I just wonder how many people actually notice the movement. It’s not a lot but enough to significantly throw the sight off. I can wiggle my Sig and hear it shifting around, and if it does that you will not get your sight zeroed in.

One of my favorites, this gets me not only on paper but on the center, I use it to make sure my scopes are off and they are not, awsome and easy to use.

This is awesome. Sends a green laser beam right down the shotgun barrel and seems to be very accurate. It is a great tool for learning to shoulder and mount the gun for home practice. After 2 years of trying to learn to shoot with both eyes open, this laser beam showed me that now, finally, my gun is in fact pointing almost exactly where my eyes are looking. Great confidence builder.Properly utilized, this could also be used to help adjust gun fit. Once you shoulder and mount the gun, the laser beam will tell you how your barrel lines up with your eyes and your sights. Adjust fit as desired.It is not great in very bright like, but I did not expect it would be.Green laser is better than red laser.I just order the 9mm version to practice my draw and intuitive aim with my Sig.BTW: Some have complained that there is no "on-off" switch and that the batteries have to be removed to turn off the laser. Solution: just unscrew the cap 1/2 way. The laser will disengage and the batteries can stay in the shell.

I feel like any negative reviews are based on unrealistic expectations. These bore sights are not a “magical” zeroing tool, they’re just a tool. If used as such they make sighting in a lot quicker and easier. This will get you on the paper but you will ALWAYS need to fine tune and adjust to achieve a proper zero. Build quality is solid and green laser is very bright even outdoors in the day time.

So I put this into a boom stick and adjusted the red dot to be perfect at 30yards. Then opened breach turned the laser 180° , closed breach still was perfect, opened breach again ,turned laser , still perfect. Then I took it out and put into a different boom stick that already had a red dot sighted and tested on targets out to 30 yards . It was 99% on the dot ! I bought the green one to contrast the red dot optics.

the laser itself is not bad, but it does not fit tight in the chamber and thus it leads to wrong results

Green laser was easier to see
