So I'm one of those guys that can't leave well enough alone. I love the green cerakoted Gascans, but don't really care for the 5.56 black "O" that comes on there. I see that one of the tan cerakoted Gascans has the American flag "O" design. Is there a way to switch the O's? Is it as easy as heating it up with a hair dryer and peeling it off and placing the new one in? Would I even be able to buy just the "O" without having to buy both pairs of Gascans?
