I started my airsoft DIY with something simple. I turned a 2 point sling into a 1 point bungee sling like the one in the pic. The clip is too big to fit on the gun so I've used para cord and it looks not bad. I'm going to stitch the ends so they don't slip out it, it holds the guns weight just now but ain't very secure. Tomorrow I'm going to attempt a padded phone cover.
