The Dieter CQD Sling is made with BlackHawk's 1.25 inch T-13 webbing. It is wider and softer than normal webbing and works great in the buckles. There is no chafing or scraping and it's easily adjustable for all operators. The sling was designed by Duane Dieter, exclusive trainer to teh NSWC-SEAL Teams. It is designed for maximum efficiency in all situations. Extra heavy-duty elastic assists with strikes and point shooting as well as quick adjustment in difficult situations. The metal snap hooks attach to most weapon systems, brackets, or attachment buckles.
