Make sure of the model that you get is the military model. That it has two zero settings, near (25 meters) and far (500 meters). There is a new one in the works that will accept an NVD (14 I think) for limited light use.
Some of the restrictions are self inflicted on the Operators' level. They go out and buy non standard that is not compatable with the team next door. This causes the 5 year contract lapse in which we pay top dollar for 5 year old technology.
Wat is the solution, stop buying the latest doodad that is the flavor of the month and work within compatablilty standards. I love the guys that just have to have the latest, only to find out that it does not do what they thought it would do or does not work under the environment that they must work.
Shutting up now.
