The High Speed Transition (HST) Sling is designed exclusively for high intensity dynamic entry operations where rapid cross shoulder and secondary weapon transitions are crucial to survival. Used on a weapon with a side receiver sling mount, the body loop secures the sling to a single mounting point. This arrangement allows the operator to simply arc the buttstock over the sling for an easily accomplished cross shoulder transition. Should a secondary weapon transition be required the weapon drops naturally to the offside, muzzle down, clearing a path to the sidearm and allowing an unobstructed secondary weapon transition. All HST slings come standard with an Emergency Release Buckle (ERB) to enable emergency disengagement of the sling from the body should the sling become entangled on an obstacle or in the case of a weapon retention problem.
