All the ones Ive seen in the past were mounted on the handguard in the 11-1 o'clock position or the 5 and 7 positon at the bottom. With it attached to the handguard correctly, it is very professional looking. The mounting screws are small and unobtrusive.
I just finished building myself another KISS AR awhile back and will be attaching a mount to my handgards as I have with others I built in the past. Maybe I can get to it and get you some pics of the finished setup.
