G&P trigger guard roll pin issue
I recently purchased a magpul advanced trigger guard for my G&P AR, but I have run into an issue with the installation. I am unable to remove the pin, even when I support the trigger guard ears with a block of wood and attempt to hammer the pin with a 1/8" punch. I have a few questions for anyone to answer. First off, is the size of the trigger guard roll pin on an airsoft gun the same as a RS? Secondly, will a normal pin punch do the trick, or do I need a specific roll pin punch? Finally, Are there any special tips or tricks to removing this pin, specifically on a G&P? Any help would be GREATLY appreciated.
