If you can't get it off with a punch and a hammer and you do t plan on reusing it try cutting it off with a die grinder or dremel.

AR front sights have tapered pins. They will only come out one way. I'm not sure which side. You might search ARF.com for tips.

They go in right to left ("right" and "left" are with respect to a gun aiming away from you). To get them out, you need to tap from the left.

I don't know about the .22 lr uppers, but on the 5.56 upper I had those pins were set with a press at the manufacturer. Lay a piece of leather or a thick blanket on some concrete to protect the finish, place the upper on the concrete for a rigid foundation and use a punch and hammer to bang those suckers out. When I called BCM they told me to use a mallet, if that did not work they offered to remove them for free. Try your manufacturer and see what they recommend.
