Good shape 12 gram dropout changer, Old school BE or ACI, good quality. Looks good with minor wear, seals with no leaks, OD on body of 12 gram dropout is around 1 inch. Knob is knurled. These were likely made by Brass Eagle but could have been made by ACI. Multiples available so items might vary slightly from photo but in good shape and will be tested for leaks before shipping.
