Hello, I need to remove the front sight tower in order to install a FF RAS tube, but I cant take those tapered pins out. Any tricks maybe?

Do you have the rifle properly secured in a vice? Along with that and a good hammer and punch, they will come out. You are trying to knock them out left to right?

Yep, left to right but those damn pins wont move a bit.

You can try some spray penetrant like PB Blaster, or giving the area a little heat.

[b]DO NOT[/b] remove the pins with the upper, or barrel, in a vise. That is a sure way to bend the barrel, I've seen it done more than once. Besides that the barrel acts like a lever and absorbs most of the hammer's impact. Lay the barrel on your bench and support the off side of the front sight base with something solid but malleable. I use nylon blocks 1/2" thick. Some use a chunk of wood. Find the biggest pin punch (mine is 1/4" diameter steel) you can and use it. My little 8 oz ball peen has never failed me on hundreds of front sight base removals.

Tweak, Are taper pins meant to be re-used? I removed my front sight to add a float tube and wasn't able to drive one the taper pins completely back in. I was wondering if I should have used new taper pins for the re-assembly. I am afraid that the head of the taper pin may have "swelled" from beating on it and will now not fit completely down in to the hole.
