[Herr trigger]

I recently purchaced a mint Colt series 70 government. Only problem is that the previous owner for whatever reason installed a high profile front blade and left the original low rear sight. The easy solution would be to put an adjustable rear sight on it, but I would rather return the gun to it's original condition. I have ordered a new sight from Colt. What is the correct procedure to remove and replace the staked in front sight. Thanks
