if I'm not mistaken, the pins are tapered.
drive them OUT from the small end of the pin.
if I'm wrong...someone who knows better chime in...:bad::sad:
These are sometimes in really, really tight. I had a heck of a time driving out the first ones I tried. As already stated, make sure you're hitting the small end of the pins.
That said, I have found it's sometimes easier to press pins out than to hammer them. For instance, with an old SKS that needed the front sight drifted, I could hammer as hard as I pleased without avail. When I bought a sight pusher, it moved easily.
If you're mechanically inclined, you should be able to come up with a jig to hold the punch in place against the taper pin while it's placed in a vise to press the pin out.

They don't seem to be tapered at all it is an olympic arms barrel ( I know..) and are the same size on each side but I'm driving from left to right and have tried right to left (on the other pin) to no avail.
hmm on the jig.

sometimes its just how hard you can hit them and with what. the first pins i removed where an older QPC which had notoriously hard to remove pins.
i drilled a hole in a piece of hard wood for my punch and used a 1# sledge with a 6in handle. hit them much harder than you think you should.
side note you can find a one pound sledge via sears or snapon chop the handle and if you are your own mechanic its invaluable.
Here's a link to a block to help remove and install check out the video while you are their.

Sometimes I have found pouring a bit of Kroil on the pins, and letting them soak overnight is quite helpful.
An FSB block from Brownells is often a great help. I have used one and found it to be worth the cash.
Make sure to use the right size punch when hitting them out as well, I installed a handguard on my Noveske and mushroomed a pin getting it out and had to hit it with a file to punch it out, heating the pins may help as well.
another thing i forgot to mention is to look and see if the pins have "splines" on one end or the other.
if they do...you have to drive the pins out from the opposite side from the "splines" or you'll never get them out.
push comes to shove...get a hydraulic jack and fabricate a press to press them out.
if you mushroom them (if they're soft pins) they may have to be drilled out...time to take it to a good AR gunsmith.
