    I'm wondering if anyone out there with a MPA BA or BA Competition chassis could grab a couple of dimensions for me? I'm thinking about a barricade stop type attachment for a different system and would like to know what the MPA chassis uses. I'm looking for:

    - Rotating barricade stop hole size (I believe it is 1/4" dia.)
    - Rotating barricade stop hole spacing - distance between holes
    - Chassis forend thickness where the barricade stop goes into, aka wall thickness of forend aluminum with the holes in it
    - How far through the forend does the barricade stop pin stick out of the backside when it is inserted, if at all (trying to determine how much space is needed behind the chassis hole when the barricade stop is inserted)

    Thanks a ton for the help!
