a Dent in the FSB

[ducdungt]

Hi everybody.
I have a Colt 6520 AR15 with a big dent in the FSB due to removing the gas block roll pin:mad: . I'd like to know any paint that I can touch up the dent?
Thanks for all your help
Peter

Degrease then use G96 cold blue or Birchwood Casey aluminum black, wipe dry and apply some oil.
