I bought this when I bought a scope for my 22. It was a little tight going in the barrel. It was hard to see in the daylight so I waited till the sun started to set. I zeroed the scope across my yard. The next day at the range I was hitting the target at 50 feet. Minimal adjustments to hit center. Later I bought a scope for a different rifle. Didn’t like the fit so I swapped it with the 22. This time one of these o rings broke because of the tightness. The barrel was clean. I put on another o ring and this time I put a dab of gun oil on the rings. It slides in and out perfectly now, plus I still hit paper with the first shot. This boresighter is well worth the price.

Came quickly, has extra batteries. Fits 22lr barrel snuggly. I recommend this product. Heads up, you'll need to fine tune the laser with a small allen wrench to get it to line up perfectly. Out of the box it may or may not be zeroed for your specific barrel due to length, thickness, etc.

Seems like a nice boresight to work with, but sucks when the batteries come dead. I got about 3 minutes with both sets of batteries. China junk!

This is a fantastic bore sight. I got my green dot sighted in perfectly(even tho the sight is trash and bottomed out for the up/down setting) its fantastic. I will highly recommend this product.

This laser works pretty well. I like that the batteries are somewhat easy to find AG3 / LR41. It uses 3 batteries, but I found that it is really easy for the edges of the batteries to make contact with the sides. This could lead to short circuits if a couple of the batteries are touching the edge. Out of an abundance of caution, I wrapped mine with a layer of cellophane tape to keep them together and to insulate them on the edges.Out of the box, mine was pretty close to being straight. I rotated the laser around and adjusted the hex screws until there was very little drift from center. There are four adjustment screws. Tightening a screw pushes the laser away from the respective screw.There's no power switch, so you'll want to remove the batteries when not in use, or insert some sort of thin insulator in the pack. You get 2 sets of batteries (6 total) and some extra O-rings. Mine fit nicely in my Ruger 10/22 factory barrel. The spot was pretty easy to see.It would be nice to have better battery insulation and a power switch, but otherwise I have no complaints.
