1. A recoil buffer system, comprising:
a buffer tube, wherein said buffer tube extends, along a longitudinal axis, from a first end to a second end and having an internal buffer tube cavity defined by an open end, one or more side walls, and a bottom wall; a buffer tube recoil spring; a buffer element, wherein said buffer element comprises an elongate buffer element body portion extending from a buffer element knob, wherein said buffer element comprises a buffer element cavity defined by an open end, one or more side walls, and a bottom wall; a collar, wherein a collar aperture is formed through said collar, along a longitudinal axis of said collar, wherein a collar recess extends from a first end of said collar and is defined by one or more side walls and a collar recess shoulder; a sleeve, wherein a sleeve aperture is formed through said sleeve, along a longitudinal axis of said sleeve, wherein said sleeve aperture is formed so as to accept at least a portion of said bumper therein, wherein a sleeve recess extends from a first end of said sleeve and is defined by one or more side walls and a sleeve spring recess shoulder, wherein said sleeve recess is formed so as to accept at least a portion of said buffer element body portion therein; a buffer element recoil spring, wherein said buffer element recoil spring is positioned about at least a portion of said elongate buffer element body portion, between said collar and said sleeve; and a bumper, wherein a bumper extension portion extends from a first end of said bumper to a bumper shoulder, wherein said bumper extension portion is such that at least a portion of said bumper extension portion can be fitted at least partially within said sleeve aperture. |
