Good set with major calipers - NcStar Cartridge Red Laser Bore Sighter Set / .223, .308., 30-06, 7mm

This set fit me perfect. I have each of these calibers in the safe. They won't work on a outdoor range in bright sun light, and the batteries tend to get left on. I take the batteries out after use now. Easy way to bore sight a rifle and not worry about messing up a barrel rifling crown, and you get four for the price of one!
Pros: Easy to use
Cons: Small batteries that tend to stay on
