Edgar Sherman Design Paracord Guide BLACKUsing paracord to connect your sling to a firearm is a lightweight, durable, quiet, field maintainable, repairable, modular, and affordable method. The main downside ESD experienced with this method is that the overhand knot used to tie the paracord is bulky, often untucks from under the sling, gets caught in certain gaps on your stock, and when exposed from under the sling can untie over time. ESD set out to solve these problems and in doing so designed the ESD paracord guide.The ESD Paracord Guide allows you to connect your ESD sling to your rifle with paracord and maintains a smaller profile knot that is tucked away and contained within the webbing of your sling. By having the knot stored securely in the paracord guide you no longer have to worry about the knot coming loose over time or untucking from the slings webbing and catching on anything and/or wearing into your neck.
