It depends on what vintage the plate is. The first-generation removable boltplate has a sloped face which the bolt overides as it locks up the gun. This design has machined cuts on each shoulder of the plate at the same angle as the plate itself. The second generation design has parallel cuts on the sides of the shoulder which are cut slightly below and at the same angle as the face of the plate. You need to determine which one it is first, then get a replacement ( I think Galazan sells them ). They usually do require fitting and are seldom if ever a drop-in item. KBM
