This is the SM15 from Stubborn Mule Outdoor Supply. This is a straightforward AR 15 built to last. V7 extreme environment gas tube, full auto carrier properly staked. Magpul furniture. 1:8 16 inch chrome lined barrel with AAC non mount FH. Receivers and rail are 100% made in house by free Americans. The rifle is cerakoted in coyote tan.

That’s a very nice looking rifle (and a beautiful photo).

      I tried to post a photo and link, it’s “awaiting moderation”. Sorry. Google search “Malyuk” and you’ll see it.

      • Squirreltakular

        Cool rifle. I can’t wait to see how the mag release works. Not sure about keeping the original AK safety, though…

      • Grindstone50k

        I googled “Malyuk”. Did not get a rifle. Lots of women, though.

    You guys had ONE JOB

    • heh, instead of starting a new post I edit an existing draft that was open in my browser … and forgot to change the title.

  • Title says bullpup

    in the article…. where’s the bullpup?

    lol Stubborn Mule SM-15. Can you say “over-saturated market”? Maybe you can get a MULE Tactical stock for it! I especially love how a “properly staked” carrier key is listed as a feature, as if following standard building procedure somehow makes them a cut above the rest.

      “as if following standard building procedure somehow makes them a cut above the rest.”

      Sadly, it probably does make them a cut above most.

      • Michael R. Zupcak

        lol. Agreed. In a world of $399 complete rifle kits, who has time to stake a carrier key?

        • All the Raindrops

          If referring to psa, all the bcgs I’ve seen from them recently have been very properly staked.

  • TJbrena

    Wrong title. Also, Malyuk could be translated to “Little Boy” or “The Kid”. I’ve heard different things.

  • Nashvone

    Did anyone else notice that none of the writers put their name on this article?

  • SP mclaughlin

    This is hilarious.
    I think TFB may need some “restructuring” in the very near future though.

  • Ok guys funs over title fixed

  • I ok’d your comment and thanks:-)

    • PK

      No problem. I figured if I was curious, so were others. Glad to see the article content/title discrepancy fixed.

    Im curios about this gas tube, anyone has an opinion about it?

    • tts

      If you’ve got a semi auto AR15 I don’t think it offers you any benefit since the gas tube only tends to become prone to bursting under prolonged full auto fire. I’ve never heard of suppressors causing them to burst frequently either though I’m sure its happened to someone somewhere.

      An adjustable gas block would probably be of more use to someone running a suppressor on a AR15 anyways since the suppressor would over gas the action unless you turn it down some.

      Their marketing is a bit sketchy over all to me since I wouldn’t consider the gas tube to be a ‘weak link’ (their wording). I’m sure a inconel gas tube is more heat resistant and all but they’re selling a solution to a problem that doesn’t really exist for AR15 owners.

      Now if you were in the military with full auto M16’s/M4’s and expected to be undergoing situations where you were frequently mag dumping in full auto (virtually never happens and even then the stainless gas tubes tend not to burst) then yes there would be some sense in buying it.

      IMO if you wanted to improve reliability or durability of your AR15 your money is better spent on a better bolt and/or extractors 1st then maybe 2nd work on tuning the recoil buffer and spring assembly. Gas tube would be at or near the bottom of the list for me.

      • Sianmink

        Adjustable gas block is for competition. Period. Has no place anywhere else. Which is fine, cause there’s a lot of competition-only ARs. It’s good for tuning the gas down so it runs with *just enough* gas for your lightweight bolt carrier and reduced power springs and barely-there buffer weight, and along with a huge muzzle brake gets your recoil down to pretty much nothing. Split times, bro.

        • iksnilol

          It has a place in a lot of other places. Suppressors and different climates make an adjustable gas block a big +

        • tts

          Other guns have adjustable gas blocks by default. There is nothing wrong with having one particularly if you run a suppressor on your gun.

          • Sianmink

            I’ll make an exception for two-position gas blocks, which are awful common for just that reason.

    • RickH

      I’m curious also. They have a video of them running full auto and melting a stock gas tube, but don’t show a comparative video using their “superior” tube. Hmmmmm……

  • Esh325

    You guys should post the scans as pics I the articles. I skimmed through the article and it does seem like an interesting design. It appears to be a retrofit kit for all ak74s. I kind of found it humorous they were trying to almost imply that the ak74 had a lot of recoil when anybody that has shot one knows they are some of the most softest shooting rifles in semi auto.

    I think they used to do all the Noveske Gen 1 lower…one of the editor of Recoil magazine told me.
