Cant remover ar15 barrel or A2 block sight! Tips?

Do you have a decent block of hardwood? Here's a pic of a set of barrel blocks made of plastic to give you an idea of how they work.

There was some discussion re. this several months back, conclusion, barrel blocks will work just as well. Save some money and just put two hardwood blocks together, and drill an appropriate sized hole through the middle. Use the money you save on a good barrel wrench
 
Barrel blocks were pretty much the only things used for the first 40-50 yrs the AR15 has been in production. Cheapest option as well.
 
OP the magic recipe for the taper pins is to properly set the barrel before trying to move them.
You really need the barrel assembly to be strapped down well and the gas block set. I use a piece of hard wood that I carved out a rough shape to accommodate the gas block.
They are tapered. So you want to pound them out from the smaller diameter side of the pin.
Use a good punch that is bigger than the pin head and a good hand sledge and snack the small end of the pin hard to drive it back flush with the gas block.
Once it's flush switch to a smaller diameter punch to punch it through.
If it's being an utter c*nt, heat the block up with a torch around the pins and spray some penetrating oil into the pins.
Let it sit for a minute and try again.
Proper set up of the barrel will make this job way easier to ensure you are transferring 100 percent energy into the pins and the assembly is not shifting around etc
