Stuck gas block pin in an AR15

Does anyone have any tricks for the above?

I went to install an adjustable gas block but my plans were foiled by the above.
Its a low profile gas block with 1 grub screw and a pin. I have also checked that im am trying to knock it out the correct side.

What have you guys used?

Cheers

What about applying some heat?

Drill the fucker if nothing else works?

This gets a step closer with every failed attempt.....

The pin will be hardened so you wont drill it.

I take it by your txt above that there is a horizontal cross pin through the bottom of the block which passes through a notch in the bottom of the barrel?
Has the pin moved at all?
How old is the rifle?

Is it a Stag Arms by any chance?

If the pin wont move, then you 'safest' solution is to sacrifice the gas block, take a disc grinder with a new cutting disc and skelp the bottom off the gas block and then use a grinding disc and carefully grind the gas block down until you get past the mid point on the pin and it comes free. At this point the block should come loose on the barrel can can be removed. Time and patience is the key. You loose the old block but don't risk damaging the barrel.

Yeah there is a horizontal pin and I am guessing it passes through a brrel notch (based on position as I cant see).
Pretty sure the pin has not moved at all, rifle is about year &1/2 old and its on a Spikes Tactical
Well seeing as drilling is not an option this is now plan B - cheers

i gave up eventually and gave it to my gunsmith who had nothing but problems. in the end it was heat and a hydraulic press

It is possible to drill, just have to use a drill that's harder than the material you're drilling. A $2 warehouse drill bit probably wouldn't cut the mustard so to speak, but tungsten or carbide drill bits certainly would. Go one size up and use a slightly fatter roll pin. How'd mr gunsmith go about it?
