ABSTRACT:
The tool includes a rotatable shank having a guide member releasably mounted upon its lower portion and adapted to be closely received within the muzzle portion of a gun barrel, and further includes a file member projecting radially outwardly from a medial portion of the shank and rotatable in unison with it. The file member overlies and engages the muzzle end surfaces of the barrel and, upon rotation of the shank of the tool, it "squares" and otherwise finishes such surfaces. The means by which the file member is mounted preferably is of a releasable type that includes a supportive backing member. The extent of the radial projection of the file member from the shank preferably is such that when the tool is used in association with a double-barreled firearm, it simultaneously finishes all of the muzzle end surfaces thereof.
