Update
Mad Bull XM108HP Arrived today!!! - Drool.....
Also here are some new renders for concept rail system, these had the actual gun photo based behind when rough modeling so they should be in proportion approx. The concept is to have the scope/optics slot in to the back to allow interchanges if needed. This means that the upper scope rails would not need to be relied upon and will also help on less complex construction with height tolerences.
