Yes, Simpen. I also think this should be required, atleast the the intended type of use this gadget will see.
For me for example, i work with computers (don't wanna go to deep on this one), do the airsoft bit and shooting to some extent. However, the tacticool magpul type of shooting is pretty limited due to swedish gun associations being very anti all kinds of shooting that isn't against a circular target grading from 1 to 10 points. With some exceptions.
However, what i might need a certain peace of kit to do and perform might be vastly different from what some of you guys want out of the same piece of kit.
Anyway, i'm all for it. Next review will be with some background from me.
