Soak it with AEROKROIL, muzzle down, overnight. That will do it. Oh yeah, remember "Lefty Loosey, Righty Tighty" too...For the life of me. I cannot get my 20S oem hider off.
Applied torch heat for 30-40sec...nothing.
My old 20S barrel hider came right off but FN got me a new barrel due to chrome plating flaking off inside the gas block...and this new barrel is being difficult.
The crush washer is resting on the shoulder of the barrel below the last muzzle thread. Spins freely but cannot be "tilted" even 1 RCH. Instead of a hack saw, what about a coping saw or a jeweler'I don't have a 20S but if you are having trouble with the crush washer, it seems to me that after FN placed the crush washer on the barrel then torqued down the flash hider, it crushed the washer enough that it no longer will slide off the barrel threads because the opening has been made smaller. Are there actual threads that the crush washer sits on or is there an area behind the threads that the crush washer sits in? Can't say it enough times, a picture is worth a thousand words.

Are they made for cutting steel, even "soft" steel as the crush washer is described (that's bullshit as you can see what my nippers did to it)? I figure a coping or jeweler's saw would be easier and more precise to control...
Yep, that's what I figured. No Dremel for me, my hands shake like a dog trying to crap a peach seed! A fine tooth blade in either a hacksaw or a jeweler's or coping saw if they make one for such things. I get more pissed every time I look at that *** thing. An inanimate object is trying to get the best of me!!! Again, **** FN!!!Well, I agree you are going to have to cut it. Best tool to use is the question. A very fine tooth metal saw blade or Dremmel cut disk. Be very careful though. If you are not 100% confident, use a gunsmith.
You should only have to cut once and use a screwdriver to split the washer enough to remove it.
