Buckle assembly with dual frictional levels

A firearm sling with a strap buckle assembly comprising:

• an inlet end portion where a strap is received therein;
• an outlet end portion where the strap is received therein;
• a main tensioner bar medially located within the buckle assembly and having upward facing surface of a first width and a downward facing surface of a second width greater than the first width;
• a first supporting tensioner bar located between the inlet end and the main tensioner bar;
• a second supporting tensioner bar located between the main tensioner bar and the outlet end,
• wherein, the firearm sling has a first mode of operation in which a first strap path is defined where the strap is positioned upwardly of the first supporting tensioner, downwardly of the main tensioner bar, and upwardly of the second supporting tensioner and the strap is arranged in the first strap path,
• wherein, the firearm sling has a second mode of operation in which a second strap path is defined where the strap is positioned downwardly of the first supporting tensioner, upwardly of the main tensioner bar, and downwardly of the second supporting tensioner and the strap is arranged in the second strap path,
• wherein frictional forces imparted to the strap when arranged within the first strap path are greater than frictional forces imparted to the strap when arranged within the second path strap,
• wherein the firearm sling is operatively coupled to firearm at opposing ends of the sling.
