    Thumbs up bumpstock/slidestock review

    guys while ive got this at WG im gonna cross post it here for those of you that dont go there...



    here we go:

    DemonDaves Bumpstock came in and this is the one we talked about here.

    they are now using 2 different names for the same stock and lets put them to the test and do away with some rumors right off.

    FIRST:

    the approval, if you read the approval letter you'll see how this got approved and why.

    THERE IS NOTHING MECHANICAL OR ACTIVATED IN THIS AT ALL! ITS JUST A STOCK.

    huh? thats right. its just a stock. pretty slick in how you use it but we'll get to that in a bit.

    this is just an opinion and you know what thats worth.

    it would be very hard to justify a retraction of this, as its quite literally just a slide over stock. all the work happens from the USER.

    its not hard to learn how to use it, but its very easy to use it wrong and get NOTHING. just as easy as it is to run thru a mag with it.

    a little practice and it will be a lot of fun.

    for testing purposes im gonna loan DemonDave my 5.45x39 AR upper and then we'll move over and try it on one of Mad Machinists TOK AR uppers too.

    these are the most affordable to shoot and will answer both speed and reliability questions with mid and light range ammo.


    about the "stock":

    solidly made and a nice look and not too bad of a grip either. it does limit how much LOP adjustment you have but hey nothing is totally free is it?

    its all Zytel style material and comes with good instructions and a copy of the BATF letter.

    am NOT gonna get into the proprietary function or "how to" of this..... but its amazingly simple if one has a polymer casting set up.

    why someone hadnt thought of this before is totally beyond me.

    they stuck to the K.I.S.S. approach and its refreshing to know that everything doesnt have to be engineered to death to work.


    now about those instructions...

    just follow them and its a 10 minute install max. they even give you a "how to" on using it to get you in the right direction.

    ok heres the video on the 5.45.

    first impressions?

    just takes a little practice and it seems that i cant get more than a 10 round burst on camera no matter how hard i try. just need more practice ;D

    DemonDave is camera shy, but he ripped a good 20round run right out of it and would have had more if it werent for the FTE that got a double feed rammed in it at the same time.

    thats when he turned it over to me to get the video..

    + YouTube Video

    you'll notice in the video that most of those are 2-3 round bursts and then there is a 6 round and something else..

    there is also a no reset that was just me holding too much forward pressure and not allowing the gun to cycle.

    maybe with a little practice it will be worth DemonDaves money, but my first impressions are that its not going to be a bit more challenging to get the "run" on a TOK AR.

    Thumbs up

    ok first up is the TOK AR test.

    folks this upper runs flawlessly and is a Mad Machinist style upper... i put over a hundred rounds thru this today with this bumpstock and this is what i got..

    this is UNEDITED as it happened videos of the ones that i got ANYTHING to run with.
    + YouTube Video

    & this one:
    + YouTube Video
    ERROR: If you can see this, then YouTube is down or you don't have Flash installed.



    CONCLUSION: it works and its all about how long you want to play with it on these light recoil rounds to get the right touch with it. im not a very patient person.

    so that brings us to THIS video:

    7.62x39 AR

    it instantly ran as there is a lot more recoil to work with and that is gonna be the key, more recoil can overcome the "strongarm" syndrome that im evidently giving it...

    + YouTube Video
    ERROR: If you can see this, then YouTube is down or you don't have Flash installed.



    as you can see it works in a nice burst on x39 ammo.

    instant conclusion on this toy tell me that the stronger rounds like this and the 5.45 work a lot better than the TOK or the 5.7 and i couldnt get it to ever work with the 22lr set up.

    so all in all?

    the product works but it will take you some shooting to get it down in operation and honestly i think with another mag or 3 on the x39 it would be ripping thru .....

    quality made? YES

    easy to install? YES

    easy to remove? YES

    fit 5 different "brands"? YES

    work on all calibers? NO stick with stronger rounds

    ease of use? HMMMMM time and practice is all i can say there.

    worth the price? Jury's still out on that one.

    I don't see how it can be legal when the Atkins Accelerator wasn't, they seem to do the same thing?


    Oh and try not to hold the foregrip to tight, let it glide on your hand, don't grip it.

    ah Coils you didnt even read my post did ya? LOL

    they dont work any where the same.

    there are no moving parts, there is NO acceleration or alteration of the fire rate.

    this is the principle that their approval letter is based around and why Sterlin Nixon signed off on it...

    its nothing more than a stock and anything that actually happens with it is caused by the MANUAL action of the operator not the stock itself.

    it takes some getting used to even to get it to work as you can see in the vids.

    this is not a "for or against" post. its just a review of the product by me and showing you guys what ive found out so far and the results.

    I read some of it

    The Akin's (yes I spelled it wrong before) worked in the same manor, the receiver bounces in the stock, in this case with the AR it's a pistol grip & stock assembly rather then an entire stock.
    So what your saying it's not spring loaded, it just floats?



    I'm not bashing it and understand your just giving your two cents, the Akin's thing just popped into my head right away, because that's what it reminds me of.

    I bet bluejack could make that scream....he's pretty good at bump firing, but he's a tight ass and won't buy the ammo to do it.

    I think the stock is probably good, you just need more practice with it.

    All of the problems you had were typical bump firing problems.

    This device will not work without manually pushing the foregrip forward, there is no spring to do that, it will not work automatically like the Atkins type device did. According to their sales department, if this goes over well, they will consider models for the Mini 14, Mini 30, AR 10, and, as they put it " the new platforms as well"

    ok just got back.

    YES you actually hold the gun BY the forestock and you hold the grip and rearstock against your shoulder with the right hand and the stock never moves...

    the gun is actually recoiling into you just like any other bump firing and your left hand holds pressure against/forward and that is the moving part (you).

    we actually have 2 of these sitting here now.

    and like 555th said... im actually a pretty good bumpfire-er the regular way, this takes a little getting used to the change over.

    but after several hundred rounds of TOK another 50 of 22lr, 100 or so of 5.45 and 100 of x39 its easy to see that the higher energy rounds are MUCH MUCH easier to make this work with.

    is it worth $350 is what we are trying to figure out.

    555th: i can bring one of them with me next time i come over if you want and everybody can play with it... DEMONDAVE wont mind or if you guys dont care i'll bring him too.

    $350.00 is kind of steep for what it does, $35.00 might be more realistic. I think you could achieve the same effect with a 1" thick dense foam pad on the butt plate.
