ICEMAN. That's great. My cheapie (.270 caliber shell that fits in the barrel after removing the bolt) spreads out a bit. I also have a few cheap, non balistic lasers that I picked up at various trade shows. I can shine them across the backyard to the neighbor's house, which is about 30 yards away and it is about the size of a nickel but pretty dim.
One of the freebee lasers will just fit in my barrel, almost the exact size as the .270 brass shell variety. It has a little ring on the back, which makes it easy to pull out of the barrel. I think they are a great way to get close. Follow up with a couple of shots to check accuracy and you are ready to go.
