The Feyachi Laser Bore Sight 12 Gauge Bore Sight Red Dot Laser Boresighter is built like a tank. I was thrilled whean I removed from the box it is Heavy and Heavy is good.
I have been adding ACOG and Red Dots to my shotguns and the Feyachi Laser Bore Sight saves time and ammo. I was able to align 'Sight In my Holosun HE510C-GR Elite Open Reflex in a couple of minutes. The last one took an hour of in and out to the range and 10-12 rounds of 12 gauge to get it set.
I set this on the gun rest and moved my reticle to the laser dot and the gun is on. I confirmed my zero and 2 rounds later it's Miller time. Since ammo cost more than bier these days, 2 and done is a cheap date.
The Feyachi Laser Bore Sight is easy to use, very well made, priced right and Feyachi. I am becoming a Feyachi fan boy as I also own 3 Feyachi tac lights, 2 Feyachi reflex red dots and some rings and mount accessories.
