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

Great product! I was honestly very surprised about how little packaging there is. For some reason I thought it would come in a bigger box, but it’s the tiniest packaging with just the 3 batteries and the laser bullet. The laser is very bright and is very good quality. Very self explanatory and easy to use. I love that it comes with extra batteries. I haven’t had this long enough to speak to how good it is yet or how long the battery life is, however I bought this to zero my optics i bought for my Hellcat Pro and the laser lines up perfectly with the iron sights so I’m assuming it’s very accurate. I’ll have to do some tests on it but so far this is really cool.

It works great. Super easy to use just drop in your barrel and line up your dots. I used this to line up my red dot and my laser. Also I really enjoyed that it came with 3 sets of batteries and a little case for it so you don't lose it

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!!

Very simple and easy to use right out of the box. The quality looks and feels very nice . The functionality seems to be great without having to make any adjustments. The size is identical to a real 9mm

Save your money or go with a different brand, just purchased a new optic for my 19xmos and one for my dagger. Was very excited to get them dialed in with less expense on rounds. The 9mm round laser was way off at 10 15 and 25 yards. Made sure the round was seated properly and adjusted my laser first then my optic but I had to manually adjust because the mark was way to high and to the left. Maybe I got a dud but nah this was trash
