Wozza, a Colt R75 commercial BAR Dummy gun, built on a Philadelphia ordnance receiver.  COMPLETE sans receiver.  80% Receiver externally machined for top cover, bolt guide and stop lever pin.  100% proper engraving on the top, no model number, serial number, or caliber (these 3 pieces of information were hand stamped after the engraving was rolled on).

Mag well is very tight, and receiver could use proper bluing.  Ejection port cover is included but no machining provisions for installing it have been done.
