Abstract:
A rifle comprises a quad lock multicaliber receiver, a barrel extension, a bolt, and a projection engageable with the receiver. The barrel extension includes a cartridge chamber and is securable in an end of the receiver. The bolt is slideable in the receiver and engages a cartridge in the cartridge chamber during the firing phase. The projection comprises locking bars extending through the receiver, and is moveable between locked and unlocked positions to allow for securing and removing of the barrel extension, respectively. Positioning bars are disposed on either side of the receiver split parallel to its longitudinal axis. The locking bars are disposed between these positioning bars and the barrel extension such that when the positioning bars are urged toward each other the receiver split is closed and the positioning bars urge the locking bars toward and into locking grooves to secure the barrel extension in the receiver.

Claim (Index 7):
The rifle of  claim 6  wherein the receiver has a cylindrical inner wall to receive the barrel extension and a plurality of openings in the cylindrical inner wall adjacent the split for the locking bars, and further including a screw extending through the receiver split below the cylindrical inner wall, the screw connecting the positioning bars;\n wherein when the screw is loosened the positioning bars are urged away from each other, the split is in the spaced-apart position, and the locking bars are out of the openings in the cylindrical inner wall of the receiver to permit the barrel extension to slide in and out of the receiver; and \n wherein when the screw is tightened the positioning bars are urged toward each other, the split is narrowed and the locking bars extend through the openings in the cylindrical inner wall of the receiver to permit the locking bars to move into the locking grooves to secure the barrel extension in the receiver.
