ABSTRACT OF THE DISCLOSURE Method and apparatus are provided for increasing the rigidity of a conventiontal pre-existing rifle. The rifle is of the type which includes a unitary stock extending continuously between a butt and a fore end and having an intermediate aperture with first and second side surfaces for normally enclosing a cartridge magazine; a receiver supported by the stock and having a forward receiver ring, a rear receiver ring, a receiver port with first and second longitudinal edges intermediate the rings and in substantial alignment with the aperture in the stock, and an ejection port intermediate the rings; and a bolt reciprocally movable within the receiver for normally engaging a cartridge from the magazine and urging the cartridge into a chamber within the forward receiver ring. The improvements include first and second plates fixedly coupled proximate the first and second edges of the magazine port and extending downwardly therefrom. Rigidity can be further increased by coupling a transverse lateral plate between the first and second plates. Weight and balance can be altered by coupling an insert between the plates.
