Removal of iron sight

I have a Superior Arms AR and I am looking to remove the front iron sight. Any ideas?

This depends on how the original sight is mounted on the barrel.

Original type AR front sight assemblies are held on by two tapered pins, usually entering from the right side.
Many other of todays rifles have front sight-gas block assemblies held on by Allen screws.

The pinned sights are removed by getting the rifle well braced with wood blocks and using a punch to drive the tapered pins out.
It's best to get the pins started with a "starter punch" which is just a standard punch that's cut off to a 1/2" working length.
Once the pins are moving, switch to a standard punch to finish removal.
Then use a block of wood to gently bump the assembly forward and off the barrel.
Note the the tapered pins "usually" are driven in from the right side and out from the left side, but check the ends of the pins to insure they were not installed from the left side.

The Allen screw type is removed by just removing the Allen screws and bumping the assembly off.

Thank you!!!!! I will post a picture tomorrow. It does not have the Allen bolts. They look like pins.

Are you looking to install a free-float forearm that extends longer than the front sight base/gas block will allow?

If so, you could just use a Dremel or grinder to remove the front sight and leave the gas block in place.

Out of curiosity, why are you removing the sight?

I wanted to remove it to go with the flipup style for when I am not using the scope.

In that case, the best option is to remove the entire front sight assembly and replace it with a gas block that has a rail for a flip up sight.

The only "trick" to mounting a new block once the original sight is off is making sure the block is centered over the gas port in the barrel, and making sure it's not canted to one side.

You should be able to re-use the gas tube with the new block.

I have a quad rail so I have room for the flip sights. Any recommendations on a gas block off to replace the iron sight before I remove it? I might just dremel it like stated above.

I've been running a railed HBAR retaining its standard front sight for years now, switching out between scope
and irons depending on my mood. When using the scope, the front sight has never resolved itself in the scope
picture and is therefore not even noticed.

`You sure you want to pull that front sight?
