Combining the best features of the CQB and SOP Sling designs, the CST Sling is a truly unique and versatile 3 point tactical sling design. The CST Sling features the same 1.25" wide webbing and adapter layout of the CQB Sling combined with the Transition Release Buckle (TRB) feature that has proven to be so popular on the SOP Sling. The TRB allows the sling to be quickly and efficiently extended to instantly create slack that allows for easy left/right shoulder transitions. This feature addresses a common complaint associated with conventional 3 point tactical sling designs. With those types of slings it's very difficult, if not impossible in some cases, to execute a cross shoulder transition. This creates a serious problem in an urban environment. With the TRB feature the sling can be used exactly like a conventional 3 point design, allowing all of the same carry options. However, when the need to cross shoulder transition is anticipated, simply flip the TRB release with the non firing hand thumb and the 3rd point of the sling is released to slide freely along the sling allowing you to extend and mount on the opposite shoulder. The sling, however, is still attached and still functional allowing you to "let it hang" should a secondary weapon transition be called for.
