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

Dont know the answer, but curious on the scope mount. Is that an integral base and rings? What is it?

If it shoots that well, load the action up with CLP for a week, wash it out with more CLP, then let it drain.
You don't mess with a Remington pump or semi-auto that's a good shooter

Quality? Havent run into many good options for these guns, still using 1990’s weaver rail because nothing Ive seen is any better. No issues, but curious.

Fwiw, my impression is that these guns break in with use, that they’re all a little stiff if not used much, ie before the edges are worn a bit on the stamped parts. I dont have experience with a ton of examples though. If thats true I wouldnt do anything to slick it up except maybe use it.

This may be a dumb question, so forgive me in advance if so:

Why remove the barrel?

Growing up, my grandpa had a couple of 760s and his buddies all had 760s or 7600s they'd let me shoot and I always thought of them as very neat deer guns and I've taken the trigger groups out of them for cleaning before (IIRC it's the same as an 870?) and been witness to a few trigger jobs done by hand on them, but nobody ever mentioned removing the barrel.

So....why remove the barrel?

I'm not being critical of your plan here, I just don't understand why you'd remove it unless it was to rebarrel, or clean from the breech end, which I don't think would be enough for me to justify a removal.

Take the stocks off and hose it out with a couple cans of brake cleaner, blow out with compressed air, re lube.

The DNZ work just fine, but all my 7400, 742, 7600, 760 still get Leupold std mounts

I've owned a couple 7600,s. Both were very good shooters. Right around and under an inch on the bench. I've had the trigger groups out to swap the safeties to left hand but that's the extent of my tear downs. My 30-06 was new when I got it, pretty stiff but loosened up. The 308 carbine was bought used but in like new condition, it was pretty smooth. Sold both of them to a friend I worked with for his boys. They are still stacking deer with them. You got a good rifle there, I'd spray some degreaser in it, let it drain, light oil, then enjoy it. By the way, Talley makes their excellent Light weight one pc mounts for these rifles.

Previous post i included a link of a 7600 barrel removal tool. I used this to remove my 7600 barrel and it worked great, although it was on tight. Tool engages 2 holes on the tube. I didn't need to use heat just soaked the threads with wd40 best I could. Spend the money on the tool if you mess around with a punch too much you will elongate the hole and it will become impossible to remove. There's a guy from YouTube Big Woods Bucks his name is Hal he has a good video as well. He uses an older version of the tool will post link if I can find it. Good luck!

The one thing I wanted from my step father was his 742 wood master.

My mom gave it to his biological Son, which I understand.

But he hocked it.

I’m still pissed

@Slickhill gotcha, will apply heat gradually and try rotating it at different intervals. I’ll also get the tool from TGI, just to make sure everything is correct.

@Macintosh , from speaking to some Mainers who use them on their tracking rifles and others, they’ve been well recommended. I will say the fit is perfect. I also like the fact that you don’t need to worry about ring alignment.
To you’re point, it will break in, so plan is to truly disassemble post season at some point, good to do anyway if the rain and snow get to it.
@Chris in TN all good and fair question. Simply it makes cleaning a bit easier, but more importantly, give access to take down the bolt and grease certain components. Also I’m just anal when it comes to getting new guns up and a running, just like to know that I gave it its best chance for success.

Looking at the removal tool, makes me wonder if they’d (TGI) make one with a slot for a torque wrench, like an ar armorer’s tool for consistent retorquing? In the few examples I’ve messed with for friends, it’s wild how many become phenomenal shooters with the proper tightness.

Removing the barrel also makes it easier to really clean the barrel well, including copper removal, without risking your crown and shoving crap into the action. I second getting one of the tools and trying some wd 40. Great find!

Well, I learned something today. I had no idea that these rifles could be disassembled and reassembled like this. Neat.

Does anyone know of a place that has the break down tool in stock?

I used a heat gun and a tight fitting punch to loosen the tube extension on my 7600. It was not easy to get off.

You can even swap calibers (after checking headspace). I inherited a 30-06 but converted it into a .243 after finding a complete barrel and bolt on gunbroker.
