Somewhere in the Numrich/Gunparts paper catalog they had "universal" tubes of different diameters that you could whack to length and drill for the end cap to whatever length you required. Fit Marlins, Winchesters, whatever. Brownell's had the same. Probably a tube for a 92 Winchester could be adapted, too. Doesn't sound right that a .357 1894 tube would be the same as a .44, I know that the .32-20 tube is a lot smaller than the .44. So Marlin DID have different tubes sizes for different calibers. I imagine that the 336 tubes are pretty much all the same, though, the base sizes of .30-30, 32-40, .38-55, .375 and .35 Rem are all pretty close.

So just looked on Brownells under Marlin parts. They have one tube that's pretty much for all the rest of the callibers, .44, .30-30 base, .375, .35 Rem. They list three different ones for .357 1894s, the CB, the C and the CP. You probably want the one for the cowboy. No lengths listed. If you really wanted to make sure, there's a question feature so you can ask a live person about it. Looks like they're all in stock, too.

I never thought about Brownells'. Thank you, I'll check it out right away.

I responded to your other thread...I'm in the middle of the same problem...I neede a tube for my 1984 357...its .57 and the others are .62....I called marlin and the kid on the phone told me they were all the same !!!! I got him to look up my rifle by serial number and send me the tube recommended for that rifle...should get the package Mon and will let you know....let me know if you find one somewhere else...between the 2 of us we will win this one....I've tried to find steel tubing the proper size and havent had any luck with that either...dont buy from numrich they only have the big ones (anybody want to buy a 30-30 mag tube??)

 

Strange ?? if they're universal why then have different diameters installed at the factory ? Makes no sense.

 

No matter who says that they're all the same size, they're blowing smoke and don't have a clue what they're talking about.

There is a size difference between a 357 tube and a 44.

 

I got to agree with this 100%, I would'nt fall for anyone saying anything else.

 

I'll watch for your reply. What length were you looking for? I am not opposed to having the bigger diameter except that I don't want to modify my receiver. If necessary I will machine a tapered transition from the larger diameter down to insert into my receiver. It will be covered up by the forearm anway. What length is the tube you bought from Numrich. If it is 24" I'd be interested.

 

I knew someone would have me digging through reference material. The Marlin part numbers are different because of the size difference and length difference. Part number for 1894c is 214525 and 1894cb is 214600. But to my knowledge, they did not make a 38/357 with a barrel longer than 20 inchs. You might have to get another and have then welded and cut to length. Would still be hidden under forearm stock though.

 

But to my knowledge, they did not make a 38/357 with a barrel longer than 20 inchs.

Yep, from 1996 to 2002 the 1894 Cowboy in 357 Mag was made with a 24" octagon barrel. It wasn't until about 2003 that Marlin started making them in regular production with a 20" octagon barrel. The 24" was also available in 44-40, 44 Mag and 45 Colt.

 

Weisners makes a replacement magazine tube for the winchester 92 in 32-20.I have used these; they are just tubing ,no holes or cuts. The diameter is .515" and length is 23 9/16". The part # is 21092.Google Weisners for the site.Hope this helps.These are good folks for lever action replacement parts.Checked a marlin .32-20 and the mag tube measured .532. Rim diameter on .357 mag is .427.What was old tube diameter?

 

The part numbers for the tubes I listed were from new reference material, so probably 20 inch barrels. Might have to check Numrich Arms for the older part numbers.

 

I just check and the part number for the older 1894 cowboy in 357 is 721400 with an overall length of 23 inches. This would be correct for a 24 inch barrel.

 

Tom,

I want to do the same thing sometime and convert a Marlin 1894 or a Winchester 92 to chamber a 256 Win Mag. That seems like a nice round despite it not getting the attention it deserved.

Can you post pictures of your progress on this thread. I'd love to see how things are turning out.

 

just got the 357 mag tube from marlin and its the right size....need to order from your serial number so the guy on the phone cant mess it up...

 

You want to bet?

 

Brownell's has mag tubes that you cut to length. I've used them with no problems.

edit: Below Stans4 has a link to the one at Brownells

 

I had a few min so I thought I'd help out.

I looked over on Numrich and found this one. I'm pretty sure this is what you are looking for.
Magazine Tube, .357 Cal., 23'' Overall Length

Have fun with that project,

I looked on Brownells and they don't have them for .357, so I looked over on Numrich and found this one. I'm pretty sure this is what you are looking for.

Ok, just went looking, Brownell's still lists the tne CB tube I saw previously and says "In Stock":
MAGAZINE TUBE - Brownells

550-000-091WBMagazine Tube
Mfr. Part: F406305

On the site, select Marlin for mfg., 1894 for model, "receiver parts" and "magazine tubes" to see them all. You don't always end up with the same parts on Brownell's with searches that should have the same results. So don't give up with only one search, try a different method.

I understand this is an old thread. but a comment FWIW...if replacing a mag tube on a model 375 and manbe others rifles. know a couple things: barrle shave two dovetail, one to anchor the fore stock and sling swival and a second or tube anchor dovetail.

I wanted to extend the mag tube on a 375 and this has me holding off, for present. might have to do picky work-around...
