Stiletto Systems Debuts New Ukranian Sniper Rifle – STL-016

Stiletto Systems, a joint Ukranian and British venture, has publicly debuted the new sniper rifle for the Ukranian Armed Forces and national Guard. The new rifle is chambered in .300 Winchester Short Magnum (WSM), giving the rifle an effective range past 1,000 meters.

The .300 WSM, despite having the name “short” in its naming, is actually as powerful as the original .300 Winchster Magnum. The .300 WSM in instead a shorter and squatter case which allows the powder to be closer to the primer’s flash hole. When ignited, this gives the .300 WSM a more consistent burn and thus improves the accuracy of the rifle.

The new STL-016 was shown with an adjustable stock and comb, using a Mosin Nagant style action bedded to a wood or laminate stock. (Actual wood would be an odd choice, given the swelling of the material in a military environment, which has largely given way to fiberglass, polymer, and metal chassis systems).

Specs (Courtesy of

The rate of fire the new rifles is about 20 rounds per minute.

  • Sighting range (depends on scope) – 2000 m

  • The blank range on the chest figure height 0.5 m – 470 m

  • The direct fire range at a body figure with the height of 1.7 m – 750 m

  • The accuracy of the battle rifle R100 at the distance of 300 meters. – No more than 1.2 cm

Its reported that Stiletto Systems is gearing up for production within the Ukraine, however no details have been released at this time.

  • Lt. Dan

    1.2cm at 300m ???

    That seems like a REALLY tight group

    • Anonymoose

      Glorious Slavic Dwarf Magic.

      • Jake

        under the old cccp wasnt it ‘slave dwarf magic?’

        • PK

          Where do you think the word “slave” comes from?

        • borekfk

          “Magic” is a construct of the old bourgeoisie to keep the proletariat in line. For simply mentioning it is a six year sentence in the gulag.

    • PK

      Yes, but technically it’s doable. I’m not holding my breath that the pictured rifle is going to do it, but it is doable.

    • DW

      Stalin guides the shot

    • iksnilol

      Not unusual in the high end market tho. The Lobaevs get that kinda precision, and some German rifles do as well.

      In short, it is possible, just takes some more money.

  • Anonymoose

    >70-year-old nugget rebarreled and restocked for .300WSM
    Pick one.

    • CourtLively

      Re-chambered garbage rod = boring. Next please.

    • Anomanom

      It says “Mosin Nagant style action” so I do not think it is a re-barreled action. In addition Mosin Nagant bolt edifice would not fit a 300WSM cartridge or be able to extract it since 7.62x54r is rimmed. Perhaps they just use design for rifle bolt that is well known locally.

      • Xtorin O’hern

        the .300 WSM cartridge has almost the same rim diameter, the caliber change could be done with a new bolt head, magazine, and barrel, all in all its still a garbage rod

      • Ken

        They might only have to mill out the magazine opening to allow the cartridge to feed. The bolt head, mag, and barrel are easy to do.

        Hopefully, they square the lugs on the receiver too.

    • jcitizen

      I would have thought the actions would be new. I remember that even the Chinese were selling new knockoffs a decade ago. Knowing the Ukrainians and their penchant for perfection. I’d think these are probably better machined that the Russian originals – however – don’t forget that the rifle dominated the Olympics for accuracy for 30 years. I have no doubt the action was part of that formula – it sure doesn’t seem like it was the ammo.

      • Anonymoose

        I bought a Chinese nugget once and it had an Izhevsk bolt in it. I would assume there’s enough bolts to go around that they don’t really have to make more. At least I think Century may have some supply of new-in-box bolts to swap out crappy, rusty, corroded bolts.

  • Martin Grønsdal

    is that a california-legal stock, or something?

    • Anonymoose

      It’s a bolt-action, so that wouldn’t matter. It does look like a sturdier alternative to the those fugly gooseneck stocks that are popular right now, though.

      • Billy Jack

        And they’re just going to outlaw putting fingers into holes next. Not sure why they even bother out there anymore.

        • Gus Butts

          Some girls welcome the thought.

          • Billy Jack

            I can understand why they hate guns and bowling. To much excitement.

      • gusto

        looks like a GRS or KKC stock to me with some work done, even the color

  • alex waits

    Looks like a “Bubba’d” Mosin Nagant.

    • Ryfyle

      ‘Cept Bubba took his time and had a clear thought about how to design it. Personally, I would just make more Mosins developed around domestic chamberings.

  • Gary Kirk

    “The 300 WSM, giving the rifle a range past 1000 meters”. And a barrel life less than 100 rounds.. God those things eat throats..

  • That… is certainly the most professional-looking sporterized Mosin I’ve seen.

    • Billy Jack

      It better be. The guys lookin back at you over there do not scare so easily comrade.

  • Ryfyle

    That’s A nice Mosin. Hopefully Ol’ Bubba can learn a thing or two from his Ukrainian counterparts.

  • Joshua S.

    I don’t know why you’re all calling it simply “another mosin” that’s about as accurate as calling something like the Ruger Hawkeye a “another mauser.”

    Unless we get more details proving that it is a rechambered mosin action and not a mosin type action. Then I’ll have been proven wrong.

    • Anonymoose

      That’s clearly a Mosin bolt in there, though. A Mauser and a Ruger are pretty visibly distinguishable.

    • It IS a rebarreled Mosin action

  • Frank Grimes

    Junk action and a wood stock.

    I hope they lose.

    • iksnilol

      Sorry for having class.

  • jamezb

    Nagant-a-licious. Reminds me of the Finn’s bolt sniper..

    • jamezb

      TAK-86 sniper rifle in action.. look closely at the bolt.. many of the rifles these were built from were pre-revolution era !!

      • mazkact

        TAK-86 is the top of my Grail list. We will likely never see them in the US so I placate myself with my M28/76.

  • Jaehaerys Targaryen

    Why not just clone a Remington 700 action? Nothing wrong with the Nagant, but it wasn’t designed to be highly accurate.

    • Anonymoose

      A Savage, Ruger, or Winchester controlled-feed would be better.

    • iksnilol

      Because the Remington action isn’t that good?

    • Just say’n

      Accuracy is found more in the barrel, bedding & trigger than the action. The Finns made some mighty accurate rifles based on Mosin actions. Even my M39 shoots 1 moa and it’s just a run of the mill standard issue rifle of the era.

    • jcitizen

      Mosins dominated the Olympics for 30 years after it was introduced – I’d say that was accurate enough.

  • El Duderino

    I’ve had a number of off the wall rifle ideas, but a Mosin in .300WSM with an adjustable laminate stock isn’t even something I’ve ever considered…

  • Kitten

    .1 MOA accuracy…

  • jay

    Same power? Doesn’t the .300 WM have a range of 1500 yards? That’s five hundred yards more than this short, no?
