Was wondering if WMD had any tips for removing the gas block on my M&P15. I was able to remove the roll pin holding the gas tube no problem with a punch, but how do I remove the pin below it? It's on both sides and won't come out with a punch. Also I did remove the set screw which was on the bottom of the block - still wouldn't budge. Also, any tips for removing the flash suppressor? It's an A2 style and I don't believe it's perma, but the fucker won't come off with a wrench. Pics below.
