Review: Kynshot AR-15 Buffer Damper (VIDEO)

Screen Shot 2014-11-23 at 10.58.32 PM

A company called Kyntec sells the Kynshot buffer dampers for ARs, and a similar product for shotguns. I’ve been using their AR-15 Kynshot for the past six months and it’s been used in two of my 3-gun competitions this year. It’s an awesome product and anyone looking to optimize their AR should consider this fantastic accessory.

It installs in a snap and it’ll run you $109. Here’s a quick video on the installation and some commentary:

As I discuss in the video, I have this in my competition 3-gun AR, and even though it shoots really flat I did notice a positive difference after installing the Kynshot. I imagine if you have a stock gun with no modifications, you’d see a bigger difference.

This product is useful for shooters who want less recoil or for shooters who are firing multiple shots in a short amount of time. Competition shooters and hunters come to mind. In 3-gun for example, we often have to send two shots into cardboard targets and so all efforts to keep your gun shooting flat will help speed things up. For hunters who need to take follow up shots, reducing recoil is helpful. There are also clear benefits for law enforcement and military, seeing as they often fire shots in rapid succession.

If you’re just the weekend plinker, I’m not sure the Kynshot is for you unless you simply love pimping out your AR with every gadget and accessory on the market. Bottom line though is that the Kynshot has worked really well for me and it’s staying in my competition gun for the foreseeable future.

    Um… AR Buffer review without a highspeed video of bolt bounce? No highspeed or full auto audio capture testing for exact cyclic rate or rpm? No impulse measuring (force of impact) sensor? No footage even in a working gun?

    some “review” :

    • You buy the equipment to do those test and I’ll use them:-)

      • Zachary marrs

        I imagine someone who has this equipment would gladly help you.

        It’ll also help with your credibility

        This “review” is more an ad than anything, all you did was describe how it works, and goes into the gun!

        While i like this site (ok, love it) and the work and time y’all put in, this is not a review

        This is at best, an overview

        • Ok I’ll agree it’s more of an overview. Even if I knew who had this kind of gear the cost of flying there,hotel,meals and everything else just wouldn’t be worth it for this one item.
          That type of review would have to be on a very significant topic that would hold great interest to the readers. It would also take a lot of planning and man hours. It would certainly be a rare event.

          • Zachary marrs

            Oh, and if you have a modern smartphone (as an android fan this kills me, but preferably an iPhone 6) and a friend, you can get slo mo of the bcg in motion.

            While it’s certainly not the best, its still better than nothing

  • Patriot Gunner

    “Umm, uh , like yeah, um uhhh kynshot, uhh um ahh um ahh buffer, ahh um uh huh, ahh, ar15.” Good Lord this is more painful to watch than CSPAN.

    • Ethan

      Everyone has to start somewhere..

  • Zachary marrs

    Every you say “um” in a video, god kills a kitten

    Think of the kittens

    • iksnilol

      What about us who don’t like cats?

      pause more damnit!

      • Zachary marrs

        Then god makes more kittens

        It depends on your preferences really

  • USMC03Vet

    I tried to pimp out a Kalashnikov once but it cut me instead.

    ARs are a bit more subservient.

  • JSmath

    The verbal pauses didn’t really bother me.

    I was surprised this was a 5-minute long video of just talking about the piece, without really going into technical detail on how it works [even speculative, regarding hydraulic pressure/flow/how recoil is affected] and no shooting. Obviously, you did say you have been running it for most of the year now, but maybe *something* as a comparison? Friends/coworkers trying firing with and without, giving their opinion. Then highspeed and sensors and stuff would be nifty.

    • High speed cameras are very expensive and wouldn’t get enough use to be worth the money spent.
      I’ve used this same buffer for about a year and it does soften the recoil impulse. Internally the liquid used to achieve this is the highest grade of military hydraulic fluid. In other words the heaviest they use. The seal around the piston is a proprietary material and design which is part of the reason the recoil impulse is reduced. Does it slow the bolt carrier down maybe I honestly don’t know. All I can say is I’ve used a lot of buffers and this is the one that lives in my AR’s because it just works.

      • Zachary marrs

        That still tells us nothing

        • It tells you nothing only if you don’t believe the person relaying the positive experience they’ve had.
          I tend to believe people until they prove I can’t trust what they say.

          • Zachary marrs

            Recoil is subjective, this is why we want hard data

            I’m sorry, but “trust me, I’ve never lied before” isn’t good enough.

      • JSmath

        I wasn’t saying he -had to- use high-speed as much as I was suggesting he should. I am sure Chris can find someone in his list of contacts and associates that has one. In fact, I’d put money on it. 😉

        • He probably does or could find someone. As a general rule you just don’t put that kind of time and money into something like a buffer.
          If you planned out an article using every buffer you can get your hands on it might be worth it but not for one.

      • DIR911911 .

        ” very expensive and wouldn’t get enough use” expensive ,yes , but when it comes to firearms I would think the investment would be well spent. I’ve learned to check the comments before watching the videos just so as to not waste time. but will skip to checking out the website, hopefully they have something for a 308

    • Ethan

      Gosh I know! Your video was so much better that this….

      Oh wait, you didn’t make a video. In fact you didn’t produce anything of value to others. Rather, you spend your time criticizing others.

      Others, who in this case have graciously chosen to spend their valuable personal time producing videos that provide free information to schmo’s like you.

      Good. Job.

      • JSmath

        I gave constructive criticism, with usable suggestions instead of just baited or guised negative remarks. You could learn to identify the difference. My response is easily one of the least insulting to the author, and at the very least, not nearly as pompous as your reply presumes.
        What the hell is wrong with you?

        • Ethan

          Did I stutter 😉

  • Sulaco

    I have been trying these types of aftermarket products starting with the “recoil reducers” for pistols like the then new Glock, filled with liquid mercury back in the 70’s. I have never found one that improved function; nay most often impaired function or flat stopped the weapon from cycling.

    • JumpIf NotZero

      Handgun ones are the worst! I got a free one from a big name in that “field” and the only thing it did was make the gun stupid hard to rack.

  • JumpIf NotZero

    The lengths people go through to avoid proper technique too!

  • Steve has covered this dozens of times and that is we don’t do paid reviews for anybody for any reason. Using the word shill has gotten past old a long time ago.

  • tazman66gt

    So…how is this different than the Endine recoil buffer since it pretty much looks the same as the Endine system that has been around for a while now.

  • Zachary marrs

    Because recoil is VERY subjective.

    Because simply rattling off specs and showing the install ISN’T a review?

    Placebos are VERY common in the world of guns, especially with all the super über duper recoil reducing gizmos that at best do nothing, and at worst reduce reliability, so without any hard data, this will stay in the drawer with all the ak and sks and glock buffers that do absolutely nothing

    • Dan

      You sure do a lot of whining around about what they could have done, put your money where your mouth is and just buy the damn thing and try it out. It would be a hell of a lot cheaper than investing in high speed cameras to do a proper review of a product on a blog that 99.98% of the people demanding a full scale review will even consider buying. Put up or shut up.

      • Zachary marrs

        I imagine they have a smartphone that can take slow motion video

        The whole point of a review is to tell people whether or not the product is worth the money, so if I have to buy the thing anyway, wouldn’t you say this is a pretty poor review?

        • Dan

          Did he not tell you whether or not it was worth the money? As a consumer isn’t it your responsibility to seek out other opinions/reviews? I don’t remember seeing any promise of a thorough full scale technical review. What i saw was a writer for a blog write about his experience with a product and thing give his opinion on the performance. I didn’t expect anything more. Sorry if i came off as an ass.

          • Zachary marrs

            Again, recoil is subjective

            Is it worth it? I doubt it. What can this do that a $20 H1/2/3 buffer can’t?

          • Dan

            Now that we can agree on.

  • iksnilol

    False asnwer comrade.

    It tried to cut him with a shiv made from rebar and a broken vodka bottle.

    @USMC03Vet:disqus , you deserved it. You tried to tacticool Kalashnikov, Kalash cut you for being stupid.

    /joke

      ….aaaand this is why I read TFB.
