Default CA7 buffer tube removal, have tried heat nail polish, wont come off!!!

Franklin Armory CA7 how do you remove the buffer tube? Have had it in a vice, Have put a torch to it , Have put a heat gun to it, Marred up the pistol tube. Dont care its throw away. But Im trying so hard to unscrew it Im worried to bend the lower receiver. I m at a complete loss.

Answer:
Heat Gun 2 times 5 minutes. Torch 2 times 5 minutes would not budge. Then cooled down finally came apart with a pipe wrench and the tube is tossed. Man just put a castle nut already.

The trick is to heat up the RECEIVER while keeping the tube cool.
If you heat up BOTH PARTS, they both expand and you don't get any temperature differential expansion.
Heating only the reciever will make the receiver expand which frees up the thread fit, making it easier to unscrew.

Channel locks, vice block and no heat worked just fine for me.

You guys are overthinking it

Do you use scrap leather to protect from the channelocks or just mangle the tube?
Some people like to keep the original parts without any damage so they could put the gun back to factory stock at some point in the future if needed.

Strap wrench worked like a charm for me. Very cheap from Walmart.

There is no castle nut on the CA7 buffer tube.
The buffer tube retains the endplate without a nut.
Franklin Armory does put loctite on the threads.
