The D3 Sling features our proprietary Quick Detach Tri-Glide (QD Tri-Glide) providing one-handed transition from two-point to single-point sling configuration. The quick adjust system enables rapid transition from carrying a slung rifle comfortably to a stable combat ready shooting position. The D3 Sling also features a comfortable low profile hydrophobic pad, inspired by Arc'teryx climbing harnesses, one of the world's leading mountaineering companies, to provide unparalleled comfort and stability without adding weight or bulk. All D3 Slings include a QD Swivel Mount with Recessed Plunger on the back end (stock/receiver attachment point) to eliminate the risk of accidental sling disengagement from the rifle, and a QD Swivel Mount with a Non-Recessed Plunger on the front end (handguard/QD Tri-Glide attachment point) to improve tacticity for transition between two-point and single-point sling configuration.
