So I have removed dozens of pinned flash hiders and have never had a issue having the pin drop out, I thing I have grinded to the limit before reaching the thteads on my socom upper I see the pin looks like its brocken free, I have tapped on the flash hide viced the upper and rocked the A2 flash hider back and fourth and nothing I dont want to screw up a new socom barrel any tricks to get the pin to pop out? Im letting some penetrating oil hopefully sink in
