A sling mount or attachment for the rear portion of a firearm is provided. The sling mount includes a cap and a base, removably coupled by screws around a buffer tube of a firearm. The sling mount further includes a connection loop positioned below the opening created by coupling the cap to the base. In some embodiments, the connection loop extends in a vertical plane parallel to the longitudinal axis of the buffer tube, and is centrally located underneath it. A user may attach a sling to the connection loop via a snaphook in order to accomplish a one-point or two-point sling design.
