It would have been handy to know that the keeper pins can ONLY be removed from LEFT to RIGHT when watching the 'How to change out a gas block on an AR-15 rifle barrel' video. It sure would have saved me a HUGE headach if it were to have simply been mentioned.

"Removing the Taper Pins from the front post pins can be the most difficult and frustrating part of this conversion, closely followed by gas tube removal and replacement. If you "booger up" the pins, you'll have to drill them out or have them pressed out, neither of which is any fun at all. The pins, as the name implies are tapered. They can ONLY be removed by driving them out of the gas block from the LEFT to RIGHT."
