The Mosin Nagant is a very popular rifle that can be had for under $100 and is pretty much sold everywhere. Not only are the rifles themselves cheap, but ammo is budget friendly and plentiful.
These rifles aren’t exactly tack drivers however, but what they lack in accuracy they make up for in reliability and ruggedness. Lots of people like to custimize them too, while many think it’s a sin. From polymer stocks to scope mounts, to muzzle breaks and paintjobs.

Well now you can extend the ammo capacity of your Mosin from 5 rounds to 10. A crafty member on Calguns.net designed this 10 round magazine extension that requires no gunsmithing or special tools of any kind. All you do is remove the magazine floorplate and pop in the mag extension. They’re currently in their prototype phase however with production versions due out anytime now. You can sign-up to be on the mailing list HERE to get more info as to when they’ll be available.
EDIT: A lot of people are commenting and emailing about these mags and asking when they come out. Please note, we aren’t making these and they’re still a prototype. We are not involved with them, we merely reported about it. Please see the link ABOVE for more info.










Neat idea, he’ll sell a lot of these if he can ever bring them to market.

Hey is that rifle for sale because I’m really interested in it. But if not how did you make the mag well bigger?
This is just what the mosin needs. Especially those of us with rear mounted scopes that no longer allow us to use stripper clips. I know myself and quite a few others that will order a couple a piece. I imagine these will sell like crazy.
so where do i get one of these things i hate the rounder
i want one baaaad! details on how to get one???
I am interested in these to put on my new Center Balance System Stock. This would make the finishing touches to an already nice Stock. Let me know if you are selling them.
I would like 2 of these 10 round mags. Let me know when they become available.
I hope you put these on the market. Soon I would love to have 1 for my brother and 1 for myself
I, too am interested. that seems like a worthwhile mod to do!
I am very interested in this, I just got my first mosin and want to extend the mag. Please tell me when you get these in
Face it, he’s never going to actually mass produce these
Does seem to be a little disappointing so far, no info,up-dates for a long time. Maybe the project was too big or its not a priority? Or the idea is so big that the legal part is the hold up- thats my bet.
I don’t think you guys understand. It’s not a detachable magazine, you still need clips to load it. Didn’t anyone pay any attention?
Clips are not a necessity in order to load these. If there is some legal hold up, or something of the sort, then I ask of someone working on this project to post the schematics so others can start making them. This would put some on the market & relieve legal pressure from the original project, then allowing them to move forward with higher-quality mass production.
I know its a fixed magwell. I also read , forget where, that the hold up was a different project is/has taken priority. Something about having taken outside investments in one of his other deals and he needs to deal with that first. This 10 rd magwell to me has BIG potential for someone somewhere to make and market.
i am very intersted in this. would this work on all types of mosins?
I would like 2 when they are ready
PLEASE LET ME KNOW WHEN YOU WILL HAVE THESE FOR SALE. I (LIKE EVERYONE ELSE) WOULD LOVE TO PURCHASE TWO OF THEM.
THANK YOU,
DON OBERLOH
Hi guys, just wanted to clear some of the confusion up.
We (ArmoryBlog) are not producing these, we just reported about them. You can find a link to the maker at the end of the article. They are currently not available for sale as of yet.
When will your mags be on the market, interested
thanks,
bernard
would love to purchase but are they really in the works? if not im gonna fabricate my own .
im assuming that the guy was making these from dragunov magazines which take the 7.62x54r rounds. If you were looking for somewhere to start to try to make one yourself i would recommend getting ahold of one of these magazines and possibly modifying the existing internal magazine on the mosin to fit these in. hell you you were able to get ahold of a dragunov receiver you may even be able to make the magazines detachable. hope this helps someone
Please inform me when you can provide one of these as I have a nice blonde/sportized remington 1917 that would love to improve on
Where and when can I purchse these? These would br prfrct fot sprnding a day at the rangr. I would likr tonbiy 4.
Jeez these mags are never going to go on sale… Someone please steal this guys incredible idea and actually run with it.
This is actually just an extension of the 5 round mag. It isn’t like a normal drop and replace mag, it still loads from the top with or without stripper clips. The true problem with producing these is that you must have a donor floor plate to butcher up to make the addition on the mag and have a donor AK mag spring. The tooling to stamp out “new” floor plates would make the cost WAY out of reasonable for these guns. On a positive note, I think now that I’ve seen what he has done, I can do it myself on my Mosin-Nagant.
@ Dave B, if you do figure out a design or way to make these please let us know… thanks!
