I hope this catches on, I would love to buy some new parts for mine - right now I have Jet Black frames with the Black O strap and Fire Lenses.
These are just a customizable as the Crowbars and come apart fairly easily - the lens is really the hardest part. Here are some pics of them taken apart and how to take the strap off the riggers (taking the rigger off is the exact same as the C-Bars and the lens is the same as any other lens it's just harder to line it up when putting it back):
All parts taken apart:
So to take the strap off just find this notch:
Then, put something in there (flat head screwdriver works best):
Then, pry it off easily:
To put it back, just pop it in.
