Feyachi Bore Sighting Laser 223 5.56mm/9mm/7.62x39mm Switch Red Dot Laser Boresighter with Tail

Works exactly as needed. Also a fun toy for my cat lol

As advertised, great alignment, laser great, very stable, bright, very stable, very accurate, great value

Laser is bright and fits well. I've borrowed something similar from a friend and the button makes a big difference. Without the button, you have to twist the cap to turn off the light. Sometimes you twist too much and cap falls and bounces under something. The button fixes that potential nightmare.

I am very satisfied with this Product.

Just got the feyachi bore sighting Lazer for caliber 223/ 5.56. My first impression before I opened the small case the size of a key was ok. Small, lightweight, easy and secure storage. I opened the package and saw the bore sight along with 3 packs of batteries, and an instruction manual. The batterys come in bundles of 3 that are shrink wraped together. You have to remove the wrap per instructions. (Make sure you have a small pocket knife handy) All put together, the guality of the product feels very chincy. The product stays off until inserted into pew pew which has to be done manually. Once its in and chambered, the product turns on. It does seem to be accurate when it comes to the alignment side of things. When I first ejected it from my pew pew, the mechanism that controls on/off seemed to be stuck in the off position but with a good old smack, it nocked back into place and worked a second and third time. The Lazer itself seems to be bright enough for indoor, not entirely sure on outdoor quality.If you are looking for something to be extremely precise and well built, this is probably not for you. On the other hand it's great for a quick tweek.I will be keeping this in my pew pew case in case my site ever comes out of alignment too bad to wear I miss my target.For the price point, if you are looking for something that will get you on paper, easily transportable, and cheap, this is the way to go. If you are looking for longevity, pinpoint accuracy, and overall quality, I would choose a barrel insert instead.

It broke instantly...It's a simple 5ml laser with a red beam. Comes with 3 batteries. The rim unscrews and the battery goes in. After the battery is in there is a button on the rim that turns the laser on/off.DO NOT use the bolt/firing pin to activate the button. Mine broke the first time I tried using it. Didn't even make it to the range.It seems kind of intuitive to us the bolt/firing pin to activate the button, almost like you are supposed to. But no, after the first try using it broke the button.

Only fits a 223

Recently going through my gun safe and well, I haven’t had range time in awhile. Wondered if my sights on my .223 s were good to go. Ordered this up and my optics seem to be good to go. This is a very useful device. Easy to operate and the push button switch is a plus. Extra batteries even. I will be ordering a few more in other calibers.
