1. A compact recoil management system, comprising:
(a) a buffer tube, wherein said buffer tube comprises an elongate portion of material extending along a longitudinal axis and having an internal buffer tube cavity defined by an open end, one or more side walls, and a bottom wall; (b) a buffer recoil spring; (c) a buffer, wherein said buffer comprises an elongate portion of material extending, along a longitudinal axis, from a first end of said buffer to a second end of said buffer and having an internal buffer cavity defined by an open end, one or more side walls, and a bottom wall, wherein a buffer extension portion extends rearward from said first end of said buffer to a first buffer shoulder, wherein a buffer body portion extends rearward from said first buffer shoulder to a second buffer shoulder, wherein said buffer body portion has a larger outer diameter or size than an outer diameter or size of said buffer extension portion, wherein a buffer head portion extends rearward from said second buffer shoulder to said second end of said buffer, and wherein said buffer head portion has a larger outer diameter or size than an outer diameter or size of said buffer body portion; (d) an end cap, wherein said end cap extends, along a longitudinal axis, from a first end of said end cap to a second end of said end cap, wherein an end cap extension portion extends rearward from said first end of said end cap to an end cap shoulder, wherein an outer size and shape of said end cap extension portion is such that at least a portion of said end cap extension portion can be fitted through said open end of said buffer cavity and positioned within at least a portion of said buffer cavity, wherein an end cap head portion extends rearward from said end cap shoulder to said second end of said end cap, and wherein said end cap head portion has a larger outer diameter or size than an outer diameter or size of said end cap extension portion; (e) a spacer, wherein said spacer extends, along a longitudinal axis, from a first end of said spacer to a second end of said spacer, wherein a spacer aperture is formed through said spacer, along said longitudinal axis, wherein a spacer recess extends from said first end of said spacer and is defined by one or more side walls and a spacer recess shoulder, wherein said spacer recess is formed so as to accept at least a portion of said buffer head therein, wherein said spacer aperture has a diameter that is less than a diameter of said spacer recess, wherein an outer diameter or size of said spacer is such that said spacer fits within and is slidable within said internal cavity of said buffer tube; and wherein said buffer recoil spring is positioned along at least a portion of said buffer body portion, between said buffer head portion and said spacer; and (f) a buffer head, wherein said buffer head comprises a buffer head body that extends, along a longitudinal axis, from a first end of said buffer head to a second end of said buffer head, wherein a buffer head aperture is formed through said buffer head, along said longitudinal axis, wherein said buffer head aperture is formed so as to accept at least a portion of said buffer extension portion therein, wherein said buffer head body is formed so as to be at least partially received within at least a portion of said spacer recess. |
