This Ruger manufactured late variation barreled receiver is for the Mark I semi-auto pistol in 22 LR caliber and has the warningon the left side of the receiver that is not present on earlier variation Mark I pistols. This barreled receiver is in very good condition retaining most of its original blue finish with light wear. The barreled receiver is designed for the fixed rear sight (sold separately) and the barrel is 4 3/4" long with its front sight blade and pin missing. The bore is bright and rates excellent. The receiver is the only part on the Mark I pistol that is tracked as a firearm therefore it will need to be transferred through a dealer. Receiver and barrel assemblies do not qualify as a C&R based on BATFE's guide lines.  (file photo)

Note: nowhere on this barrel or receiver does it have the marking "Mark I".
