Thread: Need help with A2 frontsight removal

Evening,

I am trying to remove the A2 front sight gas block from my Ranger AR15 upper to fit a low pro and free float handguard.

Has anyone done this?

So far I have measured the pins to see that they are tapered and attempted to drift them out from the smaller side. I have tried heating the block and grinding off the rear of the pins to help.

I am in the process of trying to freeze the upper to shrink the pins.

I have already broken a punch...

Getting frustrated.
