View Full Version : Mauser 98 large ring barrel

March 24, 2002, 09:28 PM
I am looking for a NEW military barrel for a Mauser 98 large ring in 30.06. I have exhausted all my leads. Of course Gun Parts Corp was at the top of the list. No luck. If anyone knows where I can find one, I'd appeciate it.

There could be more, but IIRC the only large ring Mauser 98 military made originally in .30-'06 was the Belgian Model 1950, so there are not a lot of .30 military barrels out there. Plus, of course, a used barrel can have headspace problems. But try the wanted sections of the gun web sites like this one and see if something turns up.

Brownells has brand new, in the white, barrels with a military contour, that supposedly drop right in. The 30-06 one is part # 983-000-004

The threaded and chambered barrels from Brownell's are a good deal. Just one thing to remember, there is no such thing as drop in. You will still need to have the new barrel headspaced by a gunsmith.

Just a random thought.

True. I meant "drop-in" in regards to the profile fitting the stock.

Many thanks for the advice. I like that Brownells barrel. I think I'll go with that.

I bought a Colimbian 30/06 rifle .I cracked the receiver when trying to drill for scope,I only put one hole in chamber, never touched barrel area,I'm destroying this rifle, the barrel is perfect,
tight chamber, only ammo I could shoot out of it was factory and
mil-spec ammo,I was going to try a new action but I think George
said the threads are different from other large ring mausers, if
George didn't say it I'm sorry george, someone did,I paid $150
if you want the barrel and other parts I'll sell cheap, but I'm cracking the rest of receiver before i sell,

Zot, the Turks are different being small ring threads in large ring receivers but I don't recall saying that the Columbians are. Easiest thing to do is to measure the shank diameter. 1.100" = LR; .980 = SR. George

According to the All=Knowing-All-Seeing Kuanhusen Mauser book, the Columbian Mausers are the standard LR Mauser thread pattern. Hope this helps. I would still measure. Mil-Surp is still mil-surp and one never knows what one may find.

Can anyone please tell me the thread dia.;pitch and profile,ie: butress, NC/NF etc. for a large ring Gew. 98 (dated 1917). Also does anyone know where I can find blueprints/shop drawings for the 98 action?Many thanks for any help!:confused:

The thread pattern on a large ring Mauser is 12 threads per inch at a 50 degree pressure angle. We Americans tend to use a 60 degree pitch. If you thread an ASME thread pattern into a European 50 degree pitch, the barrel will never stay tight. I bought a bottoming tap that chases the threads to the proper angle. The ID of the receiver barrel hole (can't think of the proper term) ia 1.1"

I've been looking for a set of amchinist drawings or blueprints for a large ring Mauser for a time, myself. I do have a complete action sitting in the workshop. But just haven't had the time or inclination to sit down and make myself a set.

I'm not sure what you need the drawings for, but some one else on this BBS said to me, "They are not as easy to make as they appear. Like all works of genius, they look simple, but they are not."

Also, I would also love a set of drawings for a Winchester model 70.

I believe that those are 55 degree threads instead of 50. 55 degree Whitworth threads if I'm not mistaken.

Yep, your dead on. I'm not sure if that was a typo or I just messed up. Thanks for keeping me honest. :cool:
