Remington 7600 Barrel Removal Issue

[Halligan]

Hi all,
After a couple years of looking, I managed to score a barn find, an unfired 1985 production 7600 in 270 win. Since acquiring it, I did basic barrel clean/lube, and test fired it at 50 yds with irons, and managed to shoot a ragged 5 shot group, happy days. Functioned well, just a bit stiff on the slide.
Anyway, I decided it may be a good idea to break it down, as there is a decent amount of dry original grease in the action I want to remove. Long story short, I reefed on the tube with a punch to no avail, it’s rock solid. Tried a few other methods but with not wanting to mar the tube and an upcoming bear hunt decided to leave it alone for the moment.

To my understanding thread locker was used at the factory on the tube extension, so is the play penetrant and some heat? Or just let it ride for a while and let loosen up/ break in with use? This is the first time I’ve had one not come apart for me in my travels. My only concern with heat is the location being close to the receiver.

Appreciate the help all, want to make sure this old gal has a long hunting career.

Heat the tube/reciever junction with a propane torch. Don’t get crazy and get it hot enough to change colors or anything but they usually need to be pretty hot.

And a punch is very possibly going to raise a burr on the hole in the tube. I made a wrench by milling a radius in a piece of cold roll and drilling and pressing a hardened dowel pin into it. Keeps the tube supported and allows more leverage. I think the good Brownells wrench is discontinued, maybe find one on EBay or online somewhere.

Good luck
