Hmmmm seems simple enough to me. Buy one of those $12 propane torches and take the barrel off the stock, put the barrel in a vise with a towel around the clamps, clamp the barrel firmly down and slowly heat around the breech plug area. Have your tool ready and when the breech plug area is hot enuff to sizzle water, put the wrench on the plug and give it a good forceful push to break loose the breech plug. Ive had to do this quite a few times due to the crappy non working anti seize they sell. After you get it out, clean it up good and buy some TC anti seize TAPE. Its the only stuff that will work in my rifle.
