Maxim Defense CQB AR Stocks And Buffer Systems

There is nothing sexier in the firearm world than a short barreled rifle (SBR) with a sleek collapsible or folding stock. And the newest trend of integrating the MP5-A3 “two post” style of telescoping stock into the AR platform has brought a new level of both compactness and style to the market. Maxim Defense’s CQB Stock is one of the best looking options I have seen to date.

Integrating a custom designed JP Silent Captured Spring (of which I am a big fan), Maxim has built the CQB to excel in both form and function. Sliding from just over five inches in the closed position to 10 inches fully extended, the CQB also provides the shooter with a solid cheek weld throughout the range of its four positions.

Unfortunately, functional art comes at a price – MSRP on these stocks range from $395 to over $500. But, for that one deserving build, the Maxim Defense CQB will make a great addition. It’s the perfect addition to any high-budget PDW build.

  • Extended Cheek Weld, Easily installs on mil-spec AR15 lowers, Interchangeable Buttstock Assemblies
  • WEIGHT: 18.59 oz.
  • MATERIAL: 7075 Aluminum Alloy housing for optimal performance with QD mounts
  • LENGTH: 5.375” – closed; 6.875” – 1st position; 8.375” – 2nd position; 10” – fully extended
  • BUFFER: Standard, Heavy, and 9mm weight JP Silent Captured Springs.
    Standard and Heavy weight Buffer & Spring.



Finally, a CQB stock built for comfort and durability for real-world use. No buttons to push, just pull the stock to deploy. At its most collapsed position, this CQB stock only adds 5.35” to your AR15. At full extension, the Maxim CQB stock is the length of an extended carbine stock. And with 4 total positions you can adjust for maximum comfort and multiple scenarios. Rapid deployment, purpose driven materials, and the functionality you need, the Maxim Defense CQB Stock is simply the most thought out, versatile, and durable CQB stock on the market.

    I’m waiting for the Chinese knock-off versions to start coming out before I buy one. Hint, hint, UTG are you listening?

    • David Harmon

      I hope you get it, then it has an annoying rattle and the feels loose and sloppy.

    • Pete – TFB Writer

      Spend the extra $100 and support American made products.

        I’m curious about these stocks, but not 300-400 dollars curious. I’d like to try one but alas never seen one in the wild. I’d rather buy a cheapo, see if I like and invest in a good one.

        • Steve Truffer

          There’s a guy selling m231-inspired stock kits for $200. stock, tube, buffer & spring.

          • imachinegunstuff

            can you point me in the right direction. I’m only pulling old arfcom threads in google

          • Steve Truffer

            Gunbroker. Don’t know if disqus allows a link. search “m231 stock kit”

          • imachinegunstuff

            thanks found it

        • Pete – TFB Writer

          I can appreciate that rationale for sure.

  • TheNotoriousIUD

    Anybody have any word on how these handle FA?
    Does each come with all three springs?

    • Spencerhut

      Plenty sturdy. The ones we sold only had one spring.

      • TheNotoriousIUD

        Mine is a little squirrely when it comes to buffer springs and weights. Took me forever to get it dialed in. Im hesitant to mess with it.
        But I have always wanted one of these.

  • JumpIf NotZero

    lol, nothing is sexier… IN PICTURES.

    It’s like the entire AR world saw the MP5 stocks and got jealous – except that MP5 owners know that stock kinda sucks. If I’m going to use my MP5, it gets the A2 stock – period.

    • Harry’s Holsters

      They do look sexy but I can’t stand to shoot or even handle them. I haven’t gotten a chance to try the AR style stocks but the buffer tube may make a huge difference.

    • TheNotoriousIUD

      So youre saying this is dumb and your way is better.


      • TheSmellofNapalm

        We should go over to his superior blog and check out his content! Oh wait….

        • TheNotoriousIUD

          He says the same thing on every post.

    • Pete – TFB Writer

      Many hours and miles behind an A3. Never found it lacking.

    • Bill

      Well it’s not a metal Remington 870 overfolder.

      • Pete – TFB Writer

        Hated that stock.

        • Dave Parks

          I want one just because it’s the shoulder thing that goes up.

  • Garmanarnar

    Calling guns and other inanimate objects “sexy” is really creepy.

    • J0shua

      I think you’re sexy.

    • Pete – TFB Writer

      For the next week, I will call every product “sexy” and put Garmanarar in parentheses. :p

    • DIR911911 .

      afraid you are in the minority on that one

      • Garmanarnar

        You say that like it’s a bad thing. Being in the majority is not an indicator that you’re correct.

    • Winter

      I’ve always considered the M14/M1A to be the sexiest rifle I’ve ever seen. I’m female but it doesn’t seem to be gender specific thing. There are lots of sexy boats, cars, guns and etc., even planes ( The Velocity XL & V-Twin for example). Come to think of it, I’ve seen some animate objects called “sexy” that maxes out the creepy factor.

  • Paul Epstein

    While I’m not actually surprised because AK furniture is always the last to show up to the party, it seems like collapsing stocks for an AK would be very straightforward and have the benefit of not needing to accommodate any sort of buffer tube.

    • Anonymoose

      Yeah, but AKs already have solid sidefolders, which are objectively the best kind of stock.

    • Vhyrus

      The biggest problem is that a collapsing stock will probably interfere with the safety or ejection port of the AK, and possibly the optic rail.

  • Anonymoose

    Weighs more than a pound and costs more than even the first-gen Troy PDW stock. No thanks.

  • nova3930

    Looking at the website it uses standard carriers too. THAT is what makes it interesting.

  • David Harmon

    Have been drooling over these for a while now. I like it’s weight that will pull the CoG back towards the shooter a little.

  • J0shua

    Fyi for those who may have missed it, there is a pistol brace version done in collaboration with sb tactical on the way in case you live in a no SBR state or just don’t want the hassle of a tax stamp.
    I am in no way affiliated.

    • Justin Roney

      Yep, I’m waiting for the brace version for a pistol build. 🙂 The JP Silent Spring has been flawless in my Blackout build, so $200 for the JP and $200 for the stock doesn’t bother me.

    • Bill

      Cool beans, I’m a happy camper.

  • Jeff S

    Anything that isn’t the Troy with integrated buffer/bcg is a good thing. Wow, that thing is a POS…

  • Budogunner

    Sorry for the stupid question, but how much length does this actually save you over a standard or magpul collapsing stock? That’s a lot of money, how many inches does it save you.

  • Winter

    I’d love to have an SBR with that stock but, in my case, any build would be classified low budget. If these stocks work that well what’s to keep the same spring design from being used with a “standard” polymer collapsible stock? Seems like that would work for shorter stocks in general.
