Modified PMAG dust covers with retaining grooves

first pic is with a zip tie to keep the cover on and protect against getting knocked off. I also have a pic of it with a ranger band which i prefer more. It keeps it tight, helps keep more dirt out generally looks neater.

Added reinforcement ridges that act as retaining grooves or can be used with a zip tie to keep cover on for a very long time. Also added side reinforcements that help keep feed lips inside the cover and reduce possible expansion.
