Grandaddy gunner - SightMark Triple Duty Universal Laser Bore Sight

Buy the red laser instead of the green. I bought the green thinking it would be brighter outside. I could not even see the light on the target so replaced the batteries. Still could not see the laser so replaced the green Sightmark with the red. The red is very bright outdoors and also costs less than the green Sightmark.
Pros: Easy to use and is very accurate and bright.
Cons: None
