FeyachiBore 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...

This company makes two styles of 9mm bore sights, I bought both. This shorter one is sized like a normal cartridge and is no less bright than the longer one. This shorter one extracts like a normal case, which is convenient but alignment is affected by touch of an extractor. There is normally a loose fit to the bore. The fit can be improved by using one layer of transparent tape with no overlap. The centering of the laser can be checked by clamping in a drill to see if the laser point shifts when rotated, both were good enough. The slide can be slowly lowered onto the longer one but needs to be dropped harder onto the short one so the extractor will hook. This shorter one will more consistently point to the right of true aim due to extractor pressure. Neither is perfect, but my preference would be the shorter one because it has a longer bore contact area and is no longer than necessary.

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.

The accuracy on this little laser sighter is great, one thing to note that I believe a few others have noted is you need to chamber this device like you would a live round for it seat properly and get the correct alignment of the barrel, otherwise your slide won't fully go into battery and it will be misaligned. The laser is very bright and I was able to see it from 100 feet in low lighting, bright light/s may affect your outcome.

This laser bore slighter I purchased for adjusting the sights on several 9mm pistols works very well!!! I have tried other laser sighters from various companies but was always disappointed that the beam projected from the barrel was not centered. Sometimes the beam was as much as 5 to 6 inches. While laser beams on some are adjustable, I shouldn't have to calibrate a device that should have been adjusted and tweaked at the manufacturer level. Setting up the laser bore sighter is extremely simple. You load the batteries into the laser capsule and screw on the end cap. The laser should function immediately. If it doesn't, you should check the polarity of the installed batteries. If they are not installed properly, the laser will not turn on!! I purchased the model for my 9 mm firearms to check and co-align my fixed sites with where the laser is pointing. The laser, if adjusted properly, will show the trajectory of a round fired from the level of the barrel exit. Please note: When you place the laser into the feed ramp of your firearm, you will need to close the slide with a little force to be certain the round is seated correctly in the barrel. Do not insert the laser round into the chamber by letting the slide-release slam forward at full power. This may lead to the laser cartridge getting damaged or lodged into the feed ramp causing a big problem. I suggest releasing the slide lock by hand and letting it connect with the laser cartridge. Once this has been done, pull back on your slide just a small amount and guide it towards the inserted laser round. You can do this several times to be sure the laser round is seated properly into the chamber. Many folks don't follow this procedure as it isn't explained properly in the instructions or on some YouTube explanations. Many ordered laser-bore fighters seem to be "off" in their orientation, when just a couple of gentle pushes using the slide to put the laser sighter in place is truly necessary. The kit is shipped with a nice little storage box to prevent losing the contents. Once manually adjusting my sights, I use this laser to see where my rounds will travel. If the point of impact on the target is not where I want my rounds to go, this laser will help you to align your metal sights and save countless rounds of ammunition to get your weapon properly sighted in. I noticed that the batteries supplied with the laser will last about 1 hour with continuous use. This laser uses relatively inexpensive button batteries, model LR41 which can be purchased in bulk here on Amazon for a great price. The red laser is bright out to about 50 yards on a sunny day. As it gets darker, you can see the laser beam more clearly. If you're using the laser at an indoor range, you should not experience difficulty seeing your beam!! I use the bore sighter with various pistols like my Glock 17 Gen5 and Glock 19 Gen5, M&P Gen I, and II, in addition to my Sig Sauer P229. With each weapon, this laser performed perfectly. My rating on this bore sighter offering from Feyachi is that i'ts a fine instrument that will serve you well and help sight-in your firearms. 🚩I rate this solid performer a 9 out of 10 due to its great price point, the level of accurate alignment, the brightness of the laser itself, and the money-saving aspect of not having to shoot rounds to adjust your point of impact on a target. Even though this laser will get you squarely on paper, it is highly advisable that once you have sighted your iron sights or red-dot scope the firearm should be taken to a rage to check the alignment in a real firing situation. I highly recommend this product for many reasons, such as saving money on relatively expensive ammunition, using the laser to practice dry fire operations, and helping you to build confidence in your ability to aim precisely and predictably!!

Easy as 1+1 = zeroed in with my long distance paper hole puncher. I will be taking it to the range to check to see how accurate it does and leave a part 2 to this review. To be continued....

Worked pretty well but kind of moves around in the chamber and dot will be in a different spot each time chambered but gives general area the barrel is in

Works great! I was able to use it with my Glock to get it dialed in!
