Im trying to remove the Iron front sight on my AR to install a handguard and I cant remove the pins that hold the front sight on. I have the front sight block to help me out but they are not budging. NEED HELP!!!
The block is made by Brownells, it has both sides clearly marked in or out. I have soaked the pins in WD40 and they still wont budge.

That is if you are actually driving the pins in the proper direction.

I do understand that they are tapered pins and yes im driving them in the right direction. Go to Brownells sight and find the Front sight block and watch the video.

Use a starter punch and get a bigger hammer.

It helps to use a punch with a slightly concave tip (I think they're called nail punches). Abandon the WD and get a good penetrating oil like Kroil or PB Blaster. And it helps if you skip the table and put that sight block on concrete so the energy of your WHACK! is not dissipated by poor coupling.

Just as a practical example. I use a taper pin punch, a 48 oz ball peen hammer and a front sight block from Brownells.

When you're sure you have the correct pin side to drive out, Hit it like you mean it.

Cut down a good punch and dish out the end of it with a dremel, this will keep it from slipping off the taper pin head............bring out the big guns and hit it hard.................

If it doesnt move at all (after WD40, heat etc), use a dremel to make the pins head a little flatter.. It will help keeping the punch on them while hitting hard.
