I am trying to install a free float rail and having trouble with the front sight removal. I've soaked the pins in PB blaster and have been using a punch and hammer but no luck. I do have the the barrel facing to the left which should be the correct side to punch out. Any recommendations on what else to try? I'm about to just take it to a gunsmith and ask him to punch them out for me.

| Get a concave tip punch so it doesn't slip off the pin as easy. Set up the upper so it does not bounce when you hit it. I use a piece of 2x4 on a sturdy workbench or have used it on a concrete floor for a really stubborn one. Hit it hard and it will move. If it has taper pins make sure you are hitting the small end. |
| The FSB MUST be supported on a very solid surface like a heavy vice on a solid workbench or a concrete floor. Any give in your supporting surface will only transfer the force into that surface instead of the heavy punch and tapered pin. Make sure you are hitting the small diameter end of the pin. This is usually the left side as viewed from the rear looking forward towards the muzzle. |
