Anyone here have any success with install and use of the BAD with a Vltor upper or Sundevil upper? I personally have a Vltor MUR upper and have seen pics of Stickman's Vltor VIS upper with the BAD installed. I know the MUR and VIS are similar with the exception of the integrated rail platform but I thought I should ask just in case. I know of some others that have the Sun Devil upper and the area around the bolt release is also recessed.
