I bought one at Walmart a few weeks ago. Looks very similar to the one from Cabelas.
I think it was $40 and works fantastic. I did a couple rifles when it was dark outside. The laser is visible for a long distance in the dark. I used a tree at about 80-90 yards away.
Dialed the crosshair right on the dot and done. Both of mine were a little high when I shot them, so next time will put the crosshair slightly above the red dot. Almost takes the fun out sighting a rifle in.
