The 1928 AC Bridgeport arrived last week and as promised the list of internals is listed below and their vendor markings. Upon receiving it I cleaned, inspected and put in a new polyurethane buffer. I have run 400 rounds thru it! Except for a couple of FTFs (magazine issue) it ran flawlessly. Need to dig up a NOS breech oiler or felt material. Have a request into Phil Ordnance for one. 1928 AC Bridgeport - Internal Parts B – (Gussack Mfg.
