Haven't had a Steyr for a while and can't remember if it will be possible?
It could work but the area where the velocity adjuster widens is very slight. It might be difficult.
I don't know if removing the remaining threads will actually work either come to think of it as it will make it narrower at this area. It will still probably screw into the block.
Maybe try running solder onto the threads and file it smooth, or try some two pack epoxy metal filler.
