Paladin Machine gasblock screwdriver idea w/pics

I've been taking a screwdriver to the range with me, but it's a pain when I get all set up in the prone position and realize I don't have the screwdriver in reach to switch from super/sub etc. Also, I want one on the gun so that when I'm out hunting, I don't have to remember to take a screwdriver along. So I made one to fit on the rifle. I made the basic L shape with a grinder and spent an hour with a file finishing it. It fits inside my MOE grip compartment along with the paperwork for my SBR and silencer. I'm happy with it. Anybody done something similar?
