ABSTRACT:
A rifle has a conventional gun stock, a receiver mounted thereon immediately rearwardly of an elongated barrel. The receiver has a forward end and a hollow forward end portion to detachably receive the rearward end of the barrel. The barrel has a rearward end portion that is tapered and which is complementary in shape to the tapered interior wall of the hollow forward end portion of the receiver. The receiver and the barrel have matching indicia marks to permit them to be properly aligned when assembled. The rearward end portion of the barrel has a pair of concave shaped wells which are substantially aligned, but partially offset, from threaded apertures in the receiver. Screws having rounded inner ends are mounted within the threaded apertures and penetrate into the wells and forcibly draw the barrel and the receiver into tight engagement with each other.
