Got a Colt M4, but i cannot knock the front sight pins for the life of me, I realize they are tapered, so I know I am knocking the right side, and I am tried in my drill press and i am worried of damaging the barrel. I think I am going to have to cut it off, best way?
thanks |

Make sure your working on a good solid surface. A flimsy table top or work bench only absorbs the energy from your hammer, instead of transferring it to the pins.
You may also want to invest in a nail set for removing and installing FSB pins. The concave tip of the nail set fits perfectly on the head of the pin, better than the flat tip of a standard pin punch, and works great for busting the pin loose. The same goes for setting the pins during installation. |

They should drive out left to right........ when i said i was knocking the right side, it was a metaphorical right side. I have a sold work space, and have been supporting the barrel with wood to avoid damage, I will look into nail set instead of the different punches and stock i have been using. It soaked in CLP and even then the drill press wouldn't make them budge with a significant amount of pressure, and doing them with punches and hammer was no success, it got to the point where i was worried I would bend the barrel. |

| I'm having the same issue. Drove the front one out easily. I've flattened the "special taper pin punch" from Brownells and one other trying to get the rear one out. I also have been using a wood block for support. I just ordered the front sight bench block from Brownells, maybe that'll help. Tried heat, too... If there was enough room I'd just grind the bitch off at this point. |
