A recoil mitigation apparatus formed into a stock of a rifle, featuring a removable spring housed inside a spring chamber formed inside a pair of coaxial, telescoping tubes that slideably compress the spring when energy from a rifle is generated and transmitted to the stock and thus to the apparatus. The spring compresses, absorbing the energy and thus reducing energy transmission to the user's shoulder against which the butt end of the stock is positioned. The spring chamber and spring are accessible by removing an end cap of the apparatus located at a butt end of the stock using screw fasteners fastened into preexisting holes formed in the end cap. The spring is centered inside the spring chamber by insertion over the spring mount attached to the end cap facing inwards towards the spring chamber.
