Removing Epoxied Joint

For an older project, I had epoxied a 3/4" male adapter onto a piece of .68" aluminum pipe; all parts of the male adapter cover the pipe (not just the socket part). I abandoned that problem, and now use that aluminum pipe as a barrel. The 3/4" male adapter greatly hinders my aiming ability (more so than usual

). I need to remove it, but I am not sure how. I have tried wrenching it off with a monkey wrench; no luck. I have tried to make it slide off by repeatedly smashing it with 3/4" pipe; no luck. I think that my only option (other than chemicals) would be to use a propane torch to break the epoxy seal and then pull the male adapter off. Will this work, or will it do nothing? Are there any other methods you can think of to remove this male adapter? I do not want to shorten the barrel at all, so cutting it off is not a possibility.
If you have any reasonable suggestions, that you believe may have a reason to work (in other words, don't just post random ideas that you have no idea whether they will or will not work just to up your post count). Thanks for the input.

hehe welcome to my world
I think heating is the best idea, it tends to soften most epoxy adhesives.

hehe i noticed that random fitting on your gun..anyway i took off an epoxied part with an oxy-act torch it probably would work with a regular propane torch but i dont used propane

Using the Oxy torch was the same as using propane......

Ok... I just used a propane torch, and it quickly loosened the fitting. In a bit, I will just use the monkey wrench to take it off.
The smell of burning epoxy is DISGUSTING. I almost vomited when I was doing that. I feel like I have lost my sense of smell after doing that. It was HORRIBLE

Alright, finally removed that epoxy joint. I burnt the epoxy and let it cool off for a little while. The joint still wouldn't break. I twisted it with a monkey wrench, but I couldn't pull it off. At this point, I ripped the barrel out of the gun (another epoxy joint; why couldn't the first one break so easy

). I grabbed a piece of 3/4" copper pipe, sleeved it on the aluminum barrel (a perfect fit, by the way), and proceeded to continually smash the joint down. Finally, it broke off. I threw it as far away from my house as I could (probably not a good idea in retrospect), and the deed was done.
The gun looked like crap at this point. It was tarnished, thrashed from the wrench, had a broken barrel, and no supports. I polished both the aluminum barrel and the copper chamber, and now both shine really nicely. I just put some epoxy (grr....) on the barrel and slid it into the copper valve, and it is currently drying. I will replace the barrel supports soon and take a few pictures.
