URX4 and gas block removal

[nightchief]

Anyone ever install a URX4 hand guard, then have to service the gas tube or gas block? I'm curious about how to remove the gas block if it's snug on the barrel. Is there sufficient room under the internal barrel nut of the hand guard to get a brass punch or wood dowel to the gas block to knock it off? Would it be wise to some anti seize or aeroshell on the barrel and gas block interface, as long as it doesn't get inside the gas port?

I have an MLOK URX4 and have been able to use a brass punch through the MLOK slots to motivate stubborn gas blocks. I would think a wooden dowel of sufficient of sufficient size would also work.

Haven't used specifically for the URX gas block but PB Blaster is the best penetrating oil I have ever used to separate slip fit parts.
