Abstract: A sling for a shoulder fired weapon is described having semi-permanent pre-adjustments to quickly accommodate both carrying and shooting modes. The sling includes: (i) a forward section attached to a forward swivel or ring of the weapon, (ii) a rear section nearest to the butt of the weapon and (iii) an anchor attached about a part of the user's body, usually his arm. The forward section is attached to the forward swivel using a hook-and-pile fastener wherein the length of the forward section is rapidly adjustable, and also includes either a male or a female quick coupler attached at a second end. The rear section is attached to the rear swivel of the weapon via a conventional buckle fastener that provides adjustments in the length of the rear section, and also includes a complementary female or male quick coupler having a recess mated to disconnectably connect to the male or female quick coupler of the forward section.
