Just kidding about the pink/purple.....

But I would like to personalize my RRA Varmint 16.  Generally, I want to keep it simple.  It will only have a Eotech, ARMS #40, ??? flip up front sight, magpul on the mags.

I just want something that will make it "different" but not goofy (gold bolt carrier assembly anyone?).  I thought about a couple of stainless bits, like mag release, safety selector, etc.  Any ideas?  Pics?  (not to copy, just for ideas)

Thanks in advance.
