they raise the quad up so there is no need to fold down the armor. the fold down armor is welded in the up position.this is the best pic of the rear boxes i have found.does anyone know what the hole up and to the left of the right rear tail light was for on the m16A2?
That hole is on both M16A1's and A2's with the M45F Quadmount with interphone system. The BC-1362
