Magpul Now Shipping MOE SL-K Stock

Looking for a small lightweight stock for your AR-15? Well Magpul just recently debuted their new MOE SL-K Stock. It’s designed as a smaller and lightweight butt stock alternative for compact PDW styled rifles and SBRs. The Magpul MOE SL line of furniture, or Slim Line, is already quite svelte but their new SL-K stock is even smaller and lighter. It’s a lightweight at just 7.9 oz, or 11.9 oz with a receiver extension. It’s made out of reinforced polymer and features an angled anti-slip rubber butt pad with a rolled toe for easier shouldering. It also has an ambidextrous release lever that’s also shielded to prevent snagging and accidentally adjusting it. The SL-K stock has a 1.25″ footman’s loop for slings but also accepts a Magpul M-LOK QD sling mount as well, which is sold separatly. The MOE SL-K stock will only fit on common mil-spec style buffer tubes unfortunately, sorry commercial buffer tube users.

So far it’s only available in black with stealth gray, flat dark earth and olive drab green versions coming soon. As with all of Magpul’s products it’s made in the USA and retails for $39.95 over at


A drop-in replacement buttstock for AR15/M4 mil-spec carbine buffer tubes, the SL-K is designed for compact PDW style weapons or users desiring a small and light stock.
Features a short and slim profile, a smaller rubber butt-pad with rolled toe for easy shouldering and sure grip, and a 1.25” footman’s loop with the ability to accept an optional M-LOK QD Sling Mount for push-button style QD sling swivels. A new, unique, ambidextrous release latch minimizes rattle on the receiver extension without requiring additional locks, levers, or springs*.

Made in U.S.A.

Mounts on mil-spec sized carbine receiver extension tube (not included) from manufacturers such as Colt, LMT, Ruger, S&W, SIG, and others
Sloping cheek weld combines a slim profile with user comfort

    I wish there was a size comparison with other Magpul stocks

  • thedonn007

    I would buy a few, but I already have a pile of magpul stocks and grips that I have changed out for new versions of magpul stuff.
    Is that a LAW tactical folding stock adapter?

    For the same price as a regular MOE stock? That’s not a bad deal.

  • Big Daddy

    I have some LWRC stock I really like. More so than the MOE SL ones I have. This looks closer to those LWRC stocks. On the LWRC stocks, both the compact and sub compact models, I don’t know what they call them, but they both have shorter wider pads that work better for me. I will replace my MOE SL stocks with these in time.

    • Sianmink

      I just got a LWRC UCIW and I’m liking it a lot.
      Now to just get the stamp so I can put it on my 8″ .300 BLK. >.>

      • Rick5555

        I use the MOE SL regular version on my SBR’s. And really like it. I use to run the CTR’s. However, I like the width of the butt pad on the SL line much better. I’m definitely going to try this new stock. But still haven’t find a better stock than the MOE SL…at least for me and my taste. For $40 what have you got to lose?

    • 7n6

      Just picked up a LWRC compact stock on BF for 50$ shipped. Beautiful piece,looks 10x better than this magpul. Honestly magpul just makes a bunch of garbage- MIM and plastic.

      • Rick5555

        We can see that critical thinking isn’t your forte. I’ve never busted a magpul product. And I run some of my AR;s and AK’s real hard. Not all polymers are equal when it pertains to quality. Magpul uses a good quality polymer. Their prices are more than reasonable. What more do you want? As well as, Magpul is always coming up with new and innovative stuff….which benefits shooters…not hinder us. The M-Lok rail system is simple and yet brilliant. And Magpul is allowing other companies to use that system…without having to license it. Yup it’s open source. How many companies do that in the firearms industry? And No, I don’t work for Magpul. Just really like and enjoy their products. Now, if Magpul needs an on staff surgeon…well sign me up.

        • Big Daddy

          I think Magpul is a company to use as a blueprint for someone to copy. Good quality affordable and cutting edge products. The saying haters gonna hate is true.

        • COL Bull-sigh

          Just be careful of the $14 “Magpul” stocks and handguards you find on places like Ebay. I bought a set and a crack appeared around the QD before I finished my next range session. (I thought the Chinese writing on the mailing label was strange!)

  • Jolly

    Magpul = Apple

    ” Hey guys check out my new MOE stock”

    ‘ ..pshh don’t you know. That stock is so six weeks ago. Everybody who’s anybody is running MOE SL-K now’

    • Big Daddy

      I think Magpul makes very good products and continues to upgrade and innovate new ones. The whole tactical firearms business is fast paced as far as putting out the latest greatest new thing, if you aren’t cutting edge and pushing forward you will fall behind. I find Magpul items to be worth every penny and extremely functional as well as cost effective. They continue to give you upgraded products at a low cost. As an older shooter ergonomics rates very highly with me so their products do help in that regard. It’s not so bad shelling out $50-60 even $100 as opposed to so many other products from other manufactures that run in the hundreds and offer little. Those UBR stock were at one time cutting edge, now they are paper weights.

      • Jolly

        Oh I agree. I love magpul products. I’m the guy who just upgraded my LE 6920 with the MOE SL stock and hand guard two weeks ago. Now I see they have a new version out. I am very pleased with it. It’s just like the guy who buys a iphone 5 the day before the iPhone6 comes out.

        • ostiariusalpha

          I have the full-size SL stock also. The new SL-K doesn’t really fit my needs as I have the VLTOR A5 receiver extension, but I did find it a little funny that I’m now obsolete.

          • Big Daddy

            I don’t think the SL is obsolete I think it fills a place as does the new one. I’m not tall so the smaller the stock the better, including the butt that meets your shoulder. That’s why I like the LWRC stocks. The face of butt of the LWRC is short and wide which is great for certain types of techniques like CQB were the butt is more on your pec muscle. I really like having so many options to set up different guns for specific uses. One size does not fit all. I had a few shotguns with the piston and grip, the LWRC worked better than all the Magpul stocks I tried. The face of the butt being wider and shorter helped with recoil and spread it out over a wider space on my chest/shoulder area.

          • ostiariusalpha

            LOL! I mean obsolete in the sense that it’s no longer chic mall ninja tacticool gear, not in any legitimate assessment of it’s actual utility.

          • COL Bull-sigh

            Yes–It’s a TOOL! Who cares if it looks “tacticool” or not. Use what makes you happy and what makes the Scumbag-Low-Info-Voter-Home-Invaders go Waaaah when you go BANG!

    • Magpul

      Different stocks for different missions. The SL is a full size basic carbine stock that replaces the MOE stock which is almost a decade old. The SL-K is focused on the PDW role and is the first stock we have ever created for that mission.

      • Cymond

        I haven’t handled the -SL, but I think the older MOE looks better.

        I’m considering an ACS, Fixed Carbine, or MFT Minimalist when I build a SBR. It will mainly depend on weight & balance. Lightweight is nice, but a heavier stock might mean better balance.

        • COL Bull-sigh

          MFT Minimalist is good. If you are a pro in close quarters, you can handle it cross-handed around corners easier than with a standard MOE styled stock. I actually think they weigh in lighter than the SL-K.

    • COL Bull-sigh

      And a month from now, it’ll be the new MOE SL-*!

    • LetsTryLibertyAgain

      Investing in soon-to-be-old technology is the cost of having access to all of this wonderful new technology. I’m glad that MagPul keeps innovating, and marketing new products optimized for each market niche. In a healthy market, consumers win!

      Did you post your comment from your 1985 era Mac Plus computer? Do you complain that the new cell phones made the eight pound cell phones (that were ONLY phones) obsolete?

  • Sianmink

    Would still take a LWRC UCIW over this on a PDW rifle any day. if I had a real NEED for full-size length of pull for some reason, I dunno. A UCIW with LAW tactical folder adapter is near standard length to begin with.

  • lol



    • Magpul

      The LWRC stock is designed to be used on a propriety short tube and buffer system. The SL-K is fits on a normal carbine tube (the regular SL fits the longer A5 tube) and is shorter in tail height.

      • Big Daddy

        LWRC has 2 stocks that are very short. The shortest one is proprietary and uses a tube/buffer/spring for that stock. It’s a PDW type stock that competes with the Troy PDW design. The other one is a bit longer and looks very similar. I use both, the MOE is similar to the longer one not the short proprietary one.

  • steveday72

    The profile looks a lot like the BCM stock to me.

    • Magpul

      The SL series of stocks was both publicly shown and sold before the BCM stock. Other than a minimal profile they share very little in common construction wise.

  • nobody

    Mmm, a new MOE stock for smaller and more moe rifles.

    • COL Bull-sigh

      “MOE”: MAGPUL Original Equipment!

  • sliversimpson

    I like Magpul products and service, but I do wish they would make a super-minimalist design stock (like the MFT minimalist). I have one of those, and love the profile.

  • COL Bull-sigh

    Only if it has a Mil-Spec sized tube.

    • *sigh* There’s a long list of “If Only” with the 464. And Mossberg.

  • LetsTryLibertyAgain

    Got an AR build on the slow path to completion, and this looks like a winner.

    Now if we could just repeal the STUPID laws that restrict SBRs.
