Spigot mounted HMG inspection.

[Kev1234]

As part of an ongoing project will be installing a G30 spigot mount. I wanted to reach out to your community to try to make contact with someone who has a pillar, surface  or ring mounted GPMG or HMG on their vehicle (fired from a standing position) , so i can get some offset measurements to reference the spigot location. 

any other suggestions as to where i can get such information also greatly appreciated, many thanks.
