This is better than the sightmark. - Firefield AR-Laser Light Designator

Both the light and the laser appear to be powerful enough to get the job done. What's nice is that you can control which one you want to use. Yes you have to push @ button for the flashlight and the green laser but it's only two buttons and the nice part is that they actually work. The sightmark I used to have sometimes had problems even when a new battery existed. This is a fine piece for the money. If you can afford $7-800, get the better higher quality laser light designator. Just keep in mind the expensive ones break as easily as this one. When this one breaks, I will buy another and still have saved $500. I guess my point is how much better are the more expensive ones? For hunting or home defense this will do fine. I think this is well made.
