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

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.

Laser alignment is perfect! I placed the shell in a machinists V-block with beam focused on a wall 30' away. I rotated the case 360 degrees and the laser spot on the wall never moved. Very well machined, assembled and aligned.

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.

I get perfect zero up too 100 yrds on every optic ive used it for so far, best 15 bucks ive spent

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!!

Works as it should for quick zero. Well made and very bright. Great bargin.

The laser must be magazine fed into the chamber, it cannot be dropped in as the picture shows.. Also, unlike the picture, it comes with 3 POS batteries (shown in my attached picture) that barely lasted 30 days, just long enough to miss the return window :(

This is a great item and well made. The price is good and I'm glad I bought it. If it works as well on my friends weaponry as mine then it is great.
