New Howling Raven Prototype Mosin 10 Round Mag

Remember the Mosin muzzle brake post a few weeks back? Howling Raven, the same folks who make that muzzle brake posted a cycle test video on their Instagram page of their 10 Round magazine prototype for the Mosin Nagant rifle. It looks pretty interesting, it’s not the first 10 round mag for the Mosin however. Riflemods has been working on a Mosin Nagant 10 round mag for quite a while now, there’s also the Archangel Stocks that have removable polymer mags. Yes I know NYET, Rifle is fine comrade! This isn’t a mod that will permanently change the rifle and is totally reversible, unlike this poor Mosin.


Our prototype Mosin-Nagant 10 round magazine extension being cycled. We plan to have this manufactured out of a poly carbonate material similar to what most modern handguns are made out of. Still in the testing phase but everything is going great

    If I wanted to dump money into a Mosin to get some accurate sporting/hunting rifle then I would simply buy a different gun.

  • Vitsaus

    Now you can have 10 rounds to shoot your 5 inch groups.

    • Anomanom

      Still shoots minute of fascist.

      • Vitsaus

        You mean minute of starving peasant that had the audacity to ask why there was no butter anywhere?

        • mosinman

          obviously a true worker and peasant of the USSR would have no need for such decadence, so therefor he was a fascist spy comrade

  • Matt

    Straight walled mag for a rimmed cartridge? That will only make feeding much more difficult.

    • Raven

      Worked just fine for the Lee-Enfield.

      • S&W Matt

        Show me a sectioned view of the fully loaded Lee-Enfield magazine and I’ll show you how the ammo will auto form into a radius with the driving factor being the rim diameter.

  • David W.

    Oh man, when will this be available. I kinda want it…

  • TheNotoriousIUD

    10 rounds to take down 150 lb capitalist? Nyetsky.

    • Swarf

      150lb Capitalist? So no American then.

      See? I make joke, Comrade!

      • Rock or Something

        150 kg perhaps?

        • Squirreltakular

          And you’ve won the internet for today, imho. Not for your comment, just your username.

    • Tassiebush

      At 150lbs that’d be a vegan capitalist! Eeew gross!

  • Swarf

    I will gladly but some of these if they actually work.

  • iksnilol

    Uh, I want a 10 round mag for a Mosin as much as the next guy but making it out of polymer? Seriously? That’s just weak.

    The straight mag might feed reliably if the rims are correctly positioned (top rim should be the one most to the rear).

    • Tassiebush

      Remember there’s that anti rimlock component in mosin mags that separates top round from column which would still operate with this modification. Dang it I can’t quite remember it’s proper name?

      • Dcoil1

        The interrupter?

  • smartacus


  • Matt Shermer

    The End and his pet Bird are crying into their vodka…

    Might not stop me from wanting to try one of these out.

  • Southpaw89

    While I understand that polymer is cost effective, it would look much better as stamped steel.

  • Grindstone50k

    All these are neat and all, but I’m not buying a bunch of crap that will end up out-costing a $100 gun.

  • Squirreltakular

    Instead, could be just have a company start making modern bolt action rifles chambered in 7.62x54r? Like a Mossberg MVP or Rem 700?

  • Tom – UK

    Or I could just spend the money on more ammunition. Because its really the end of the world having to fire five rounds at a time instead of ten.

  • Tassiebush

    I added a polymer floorplate extension to my Weatherby Vanguard and it worked really well. It was certainly durable enough and it wasn’t a high wear part since it stayed in place. If I was a big mosin fan I’d definitely consider this. I presume it’d still load OK with stripper clips. Best of luck to this company.
