12 Gauge Bore Sight

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.~

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.

My review of Feyachi Bore Sight 9MM/223 5.56/12GA Red Dot Laser Zeroing Bore Sighter (ordered Nov 28, 2025)I received my 12GA laser bore sight today (1 Dec). It came with 3 sets of batteries in a nice protective foam lined box. When I removed it I was pleasantly surprised of how heavy it was. From the other reviews it is as stated. Its made from solid brass. It is probably turned on a lathe and fits the chamber perfectly.I tested its zero by rolling it on a flat, level surface (with the rim off the table) and checking if the dot moved or wobbles. An example of the technique, it's like rolling a cue stick on the surface of a pool table and checking if the tip wobbles.Next test was measuring the projected dot on a box perpendicular of the table top. Measured the dot with a caliper and measured the sight from the side to the center it was exactly center. If it wasn't center, it would have to be returned because there is no way to adjust the beam.The site comes with 3 sets of batteries and is wrapped in a 3 battery sleeve. The instructions state to remove the sleeve or malfunction can occur. Mine fit well and did not interfere with the sight so I left it together.I can highly recommend this product for a 12GA shotgun. I don't have guns of the other calibers so I can't attest to those.

My only complaint is that the seller (or whomever) could update the instructions even in the description to share that a good way to install the three batteries is to place them negative side up in a stack on a flat surface, then place the open end of the laser-round over them, tilt round, and shift the batteries up inside the unit. >> This method for me was best as the batteries wanted to rotate as they fell into the unit if i dropped them in from above. Otherwise, the unit was great.

I am a Shotgun Shooting Instructor and use Laser shells to fit guns, Train students to practice their gun mount and gun movements! This is the very best system I have used over the past 10 years. Quality control is the best; however, the three sets of batteries make their price almost FREE! The price of three batteries is almost the price for their whole package. The other two sets actually save you over 100% of the cost of the total package!Buy one and take advantage of my years of experience!NSCA Level III Instructor

I bought this to help me sight in my shotgun with my HOLOSUN green dot sight. I wanted to sight it in for turkey loads and didn't want to have to shoot a bunch of shells while trying to dial in the green dot sight. I used the laser bore sighter and it was dead on from the first shot. Great tool and glad I bought it.

Build quality was phenomenal. Accuracy amazing 10 out of 10. I will buy it again.

From the packaging to the function. Excellent product overall. Most things don’t even come with batteries and this came with 3 sets of batteries. Laser is very visible and true to the sights. Definitely worth it especially for rifles.Function is fool proof, it feels like it’s made well, nothing rattles, the metal finish is nice. Overall very happy with this purchase and would recommend if you are on the market for one.

Bright red light. Heavy metal construction.Not cheap but good quality, rugged design.

Great to see point of impact

It's a neat little gadget. It will get you on the paper at 20 yards just like regular bore sighting (looking through the barrel at the target and adjusting the scope to match up) but when that is not feasible with pumps and such, this will get you on the paper at 20 yards so you can start sighting in right away and not waste any shells. Don't expect for it to get you out to 50 yards. It's still bore sighting. Even 30 yards would be pushing it a bit unless you have a big target.

Fits nice in the chamber and saves me time and money on the range. Easy to set up my scope and it so convenient as well. Would recommend if your into setting up your shotgun with a scope or even a red dot.

"power <5mw". My bad for not reading. Why? Good cat toy. Cannot see more than 30' in sunlight.
