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

I read a bunch of reviews and I saw a few that were not good because of the laser not being centered/zeroed... A lot was oval when rolled, some put in a drill & then rotated the drill... Not really an accurate test. Some commenters stated that there's was good. I rolled mine on a smooth surface & mine was 95% accurate. No oval or wobbling. Didn't move at all, not w/my eye sight anyway. It was perfect to my satisfaction... Just got lucky I guess my purchase... Now to the range to zero everything in .. Updateaaa: The only issue is that when the laser is in the chamber. The gun does not close 100% all the way. Causing an false centering zero. So my 5 star just went to 3 stats... It's somewhat close though, but not accurate...

Why did you pick this product vs others?:Works exactly as promised. I chose this for its fair price and quick shipping, was not disappointed. It comes with extra batteries that I am sure will far outlive my need for this. It also fit perfectly in the barrel without issue.

1st Bore SighterThis review sums up more experience using a 9MM Walther PDP 4in with a C&H precision RDO:Solid attempt. Quality is great. Extra batteries is amazing. The case is an excellent touch too. But I didnt buy this for any of that. I bought a laser to bore sight with. And frankly- this doesn't do that at all. The laser is 1" off at 1meter. Extrapolate from there and a 15m zero has you so far off target that you could not reliably hit the paper to even see how far off it is. Inaccuracy is its only con. But also the only thing its intended to be good at.2nd Bore SighterSo, I had the company send out another boresighter and used it on my 4 in Full-size Walther PDP with a C&H Precision RDO and my wife's 4 in Full-size F Series Walther PDP with a C&H Precision RDO. Both firearms were already zeroed so I knew that if I made any changes it would be wrong. Upon placing the boresighter in the firearm and acquiring my target, it was off 3in to the left and low 4 in to the left at 10 yards. Now I know I could say I'm on paper so that's enough but its not if I buy a boresighter then I expect that at 10 pr 15yds I can get a hard zero without wasting ammunition to do so. The green light was bright and there weren't any issues removing it from either firearm but it's ineffective for zeroing a firearm in my opinion.

WOW.... Top quality unit.I just bought a different brand and it was off center, It could not be adjusted, it had a little hole but there was no screw driver slot or hex key in there. I returned it and ordered this Feyachi Laser Bore Sight.I ordered this one because I seen it had hex key style adjustment all the way around. I thought, if they do not have it perfectly centered at least I can fix that.The other one I bought, I set it in a v block and turned it slowly and it made a 1-1/2" circle on the wall 6 ft away. It was way far out of alignment, due to this it could not be used is align my red dot sight as it was never going to show me the center line of my shotgun bore. It was junk, but is was only thirteen bucks. Turns out trying to save a few bucks was not a good idea.When this Feyachi Laser Bore Sight arrived I did exactly the same thing, put it in my v block, turned it slowly and the laser dot did not move it stayed centered just as it should. Perfect!Other nice features: it comes in a nice case with 3 sets of batteries, and get this, the batteries have clear shrink wrap to keep them together in a unit of 3 so putting them in the Feyachi Laser Bore Sight is simple.The other key thing about the shrink wrap is the sides do not touch the metal inside. This means you can unscrew the cap and place a plastic spacer in there and put the cap back on and it will reliably stay off, until the next time you need it and remove the plastic spacer.It did fit in my Lynx 12 shotgun bore well and the extractor did grab it. I did not cycle it through the action though as that is not what these bore sights are intended to do. Closing the action and allowing the extractor to grab it did cause the laser dot to change point of center off to the left about 1/4 inch because this laser sight was not super tight in the chamber.My conclusion is to not close the chamber when using this laser bore sight, though it does fall backwards and out if your not careful when handling the shotgun.I need 9mm and .45 laser bore sights also and guess who I am going to buy from? That's right, FeyachiThe Feyachi Laser Bore Sight has my top rating for quality and value - buy it if you need it.~
