I have issue castle nut pliers, I've backed off the set screw, but cannot break the castle nut loose. I heated it with a propane torch and still can't get it loose. Any suggestions?
Kroil or Liquid Wrench + a good night's sleep. Mark the castle nut and flash suppressor to each other with nail polish. Tap the flash suppressor head-on with a wooden mallet. Castle nut will come loose with your GI pliers. When you put it back on, pass the side that sets down against the F/S on a piece of 200 grit sandpaper on a flat surface enough times to polish the edge. Put it back in the same place it came off. It'll fit perfectly.I have issue castle nut pliers, I've backed off the set screw, but cannot break the castle nut loose. I heated it with a propane torch and still can't get it loose.

Now do yourself a favor and put on a gas lock front sight with a direct connect flash suppressor. The castle nut idea is pure Rube Goldberg in my opinion.so, I had to go out of town and work instead of working on my new rifle. What I came up with was Deep Creep. I scoured every parts store, etc and it was the best I could find. I am an impatient person.
Will heat, treat, soak and sleep. To answer all the questions, so y'all don't think I am a complete dingdong:
SAI '94 production, no welds, set screw out, no GS wrench but vise grips. I've taken one off before quite easily, but this sucker is ON.
I will post pictures of my new rifle and post. It's a good one.
Removed it yesterday, thanks everybody.
