Smile R498, R632, 1220 & 2384 Magazine tutorial!!!



Log in to see fewer ads
Some magazine info!!!

Picture "A" This is a side view of the 1220, R632 and R498 mags. From the side, back, front and bottom you cannot tell the difference between a R498 and an R632. You have to look at it from the TOP to see the small but very important difference. The 1220 mag is there just for comparison, and so that you can see the similarities in the manufacturing method used to make those mags. The "angle bar" channels are formed identically.

Picture "B" Now you can see the difference between the R498 and the R632 mags. There is a small rectangular hole in the front of the follower that will allow the installation of the R504 short adapter, that is if you have one!!! In pictures "A" and "B" the 1220 mag is there just for comparison. Also you can see that the R498, R632 and the 1220 share the same manufacturing procedure for forming the "angle bar "channel.

Picture "C" is a comparison of the 1220, 2384 and the 3235 mags. When Mossberg started production of the 2384 magazines they changed the way the angle bar channel was made.

Picture "D" Shows the back detail of the 1220, 2384, and the 3235 mag. The hole at the bottom of the magazine back and front of the 1220 and the 2384 mags is to allow the tabs (which you can't see) on the mags bottom plate to be folded into the mag body which locks the bottom plate to the mag body. Only problem with this method of retaining the mag bottom plate to the mag body is that if you bend that tab to remove the bottom plate more than 2 times you will generally need a new bottom plate due to metal fatigue causing the tabs to break off.

Picture "E" Shows what the magazine bottom plates look like on the different mags. The 3235 bottom plate design is a big improvement over the 1220 and 2384 designs!!! No tabs to break off!!! The R498 and the R632 share identical bottom plate construction and attachment methods. So hopefully these pictures will answer any questions you have about these original equipment magazines!!!

A mystery mag??? A 2384 aftermarket clone??? Some things to be noted. In picture "B", the 1220 has a slot in its follower to allow for the adjustment of the mag to accomodate the SHV-L-LR ammo. So does the 2384 but I didn't post that view of the 2384's follower. The mag pictured above has no such slot in its follower, so it has to be a LR only mag. The main body of the mag looks like it was made by Mossberg, or at least on tooling originally made for Mossberg, well that is my guess. The bottom of the mag has a different base, and I really like the idea. I now know how I am going to easily repair a REAL 2384 where the tabs are broken off of the base plate that lock the base plate to the mag's main body!!! So based on the follower this is a LR only mag. The mags base plate will be easy to remove if needed, and easy to fabricate, if lost or damaged!!! Probably made with dies that Mossberg sold when they got out of the .22 rimfire manufacturing, again that is my guess. If you only plan to shoot LR I would be willing to bet money that these mags would work just fine in any Mossberg semi or bolt gun that takes a 1220 or a 2384!!!
God Bless, Frank.

Okay Frank, is this where Ed McMahon says to Johnny Carson "Now that's everything anybody would need to know about Mossberg magazines."?

Oh, heck no!!! You'll notice that I was very specific about the mags that I was talking about and picturing... Very specific. Nothing older than the 140's or 150's series of rifles. Nothing in the 40 or earlier series models, if you will notice. Just the group of rifles that I am most familiar with!!! Hope the pics are helpful!!! Copy them to your "Mossberg file folder" if you have one. If you don't have one you ought to start one!!!
God Bless, Frank.

Thanks for your magazine tutorial. It will help many, such as myself, more than one can imagine. My problem is that I have tried to insert a 1220 magazine into the magazine well of a 142 A and it will not work due to the ears on the cartridge adjustment. The only magazine that seems to fit & work properly is a R632. I do happen to have one of the R504 short adapters. Any suggestions on why the other ones that you can interchange will not do so for me?

Very nice pics, thanks tfrank, but I do have a question.

In pics C, D & E, the image labeled as a 2384 appears to me to be a 3235 magazine. I have seen this mag in an original Mossberg envelope marked as a 3235. Of course I cannot swear that the mag was original to the envelope but they appeared to me to belong together.

I was under the impression that the 2384 was a re-numbered 1220 with minimal other changes. This info supports my belief.

I believe the 3235 is the only vintage Mossberg rimfire mag with a removeable baseplate.

I would be interested in your thoughts and comments on this issue.
edited to reflect the fact that these comments are no longer relevant since the OP updated his images

Will do , but on second thought, how about selling me one of your R632 magazines that is missing the adapter? I am on the hunt for one to go in one of my 142A's and will more than likely need the adapter when I locate one .

No, afraid not at this time. I was second in line to purchase the one that chuckbisquits bought on Sunday. One can not have to many "T" bolts or Mossberg carbines.
