I removed the "C," which wasn't really all that hard and it's been done before. But what I'm actually kind of proud of are the eye covers. They started out as the jewels on the outside of the composite, shown here (not my gun, just stole the pic to show the jewels):
I popped them off the body, dremeled them down, drilled holes for the screws, and countersunk the holes. I think they turned out pretty well, especially considering how hard it is to get ahold of stock eye covers for a DMC.
Check it out, I'd love any questions/comments.
