Can The Slidefire Emulate Full Auto in a Support Capacity?

Capture

Never having enough ammo to just go out and test this philosophy, I am grateful to our own Ian Mccullum from Forgotten Weapons for experimenting to see if the SlideFire is indeed useful as a support-weapon. Turns-out, yes. While the Slidefire may not simulate full-auto, it does not maintain the POU (dangit… NutNFancy reference) by losing accuracy. On a support weapon, whose job it is to blanket an area with fire, it turns out to be rather effective.

So, those who own an RPK or perhaps someone looking to purchase one of FN’s new semi-auto SAW’s, a SlideFire or bump-stock may be just the ticket.

What say you? Would the SlideFire meet support weapon objectives?

    Nice vid! Those slide-fires look interesting. I’d like to have seen Karl shoot it some, since he is indeed experienced with the device. Watching Stage 3, I kept thinking, ‘My knees! My knees!’ Was ‘hammer follow’ the cause of *all* the stoppages?
    Lastly, thanks for the out-take at the end! What was that guy shooting?

    • Ian McCollum

      It turned out to be an SBR AR with a coockie-cutter brake.

      • KestrelBike

        The noise performance was damn impressive, then. How brutal for the RO!

      • Pete Sheppard

        I’d have thought something with ‘cannon’ in its name.

  • E M Johnson

    I quite at 6 minutes. The lack of consistency in being able to use controlled bursts and the stoppages just highlight the novelty nature of these stocks.

    • DIR911911 .

      your loss, the last minute or so is priceless 🙂

      • Nicks87

        “They cant afford to shoot that thing forever.”
        Thanks for the heads up. I went back and listened to the last minute and laughed my @$$ off. Best part of the whole video.

      Around 7 minutes he talks about how that match was one of his first times using the slide fire stock.

      >and the stoppages just highlight the novelty nature of these stocks.

      The stoppages are probably due to the gun, not the stock. In stage 3 he isn’t using the bumpfire feature and still gets 4 stoppages, 3 appear to be due to hammer follow and would be a problem with the trigger.

      • chead

        It may be an issue of hammer follow but only because the gun is short stroking due to the Slidefire. When using it off a bipod there’s even less resistance than there would be from the shoulder (as intended).

        • Ian McCollum

          It was an ammo sensitivity issue with the rifle, unfortunately.

        • Xaun Loc

          I’d be interested in seeing your explanation of “short stroking” on a GAS GUN!

    • Ian McCollum

      This video was my first time actually using the stock – it had enough potential that I have since picked up my own, and will be spending some time climbing the learning curve with it. A followup video will be coming once I am better with it.

      • Tassiebush

        I’m definitely looking forward to seeing it. It’s an interesting idea to see tested out!

      • Anon. E Maus

        Looking forward to seeing the results.
        Are you gonna keep your RPK ‘vanilla’ or will you put synthetic furniture on it to match the aesthetic of the typical bump-stock?

    • Anon. E Maus

      Done right, these things actually work quite well and consistently, just gotta get the knack of it down.

  • DetroitMan

    “Would the SlideFire meet support weapon objectives?”

    For the military, absolutely not. Too complicated, too unreliable. Full auto works better, period.

    For a civilian, what are you looking to accomplish? A support weapon requires something to support. With no squad, you don’t have objectives for a support weapon. An individual is better off with a rifle / carbine. As a range toy, sure, have fun. As a self defense weapon, forget it. Too unreliable, too cumbersome, too much liability when you spray rounds.

    • USMC03Vet

      I fireteam rush to the fridge every day. Of course that is after I’ve written out a 5 paragraph order and request departure from the coc to exit friendly lines.

      You don’t choose the tactical life. It chooses you!

      • Army11B

        Sadly, I have to put on my PT belt before my daily routine, which includes route clearance to the objective and copious hydration time. Any tactical movement requires maximum safety first and foremost.

        • USMC03Vet

          Better to wear a glowbelt than to suffer in 6 hour long ORM classes…

    • What about militia drills?

      • DetroitMan

        If it’s a drill, that still puts the weapon in the range toy category. Is your militia going to be there when something goes bump in the night? Probably not.

    • David Sharpe

      WHAT ABOUT WHEN THE ZOMBIES COME!?!?

      Just kidding, but I think it would be fun to have one of these….IF THEY WERE LEGAL IN CANADA!

    • The Brigadier

      I agree totally. We occasionally bump fire at the range when we are bored and rat-a-tatt-tat picks up the mood, but you are right on all points.

  • DIR911911 .

    if you don’t do anything else then at least watch the last minute and a half , classic.

    • JQPub

      haha yeah that was classic. have a few buds I’m gonna have to forward that to now, who always seem to find the loudest brake devices manufactured

  • Ethan

    So the slide-fire stock caused the hammer-follow-downs? I didn’t think the AK platform was that sensitive to inertia..

    • Ian McCollum

      No, the malfs were an unexpected ammo sensitivity issue with the rifle

    • AK7n6

      probably tapco trigger

  • Dave The Great

    No, this would be “fun toy” territory. Only.

    There is nothing at all wrong with setting aside a few guns purely for fun purposes (c’mon – those of us who have dozens of guns can’t possibly designate each and every one for purely utilitarian purposes. We have only so many hands. Hell, I have half a dozen flintlock pistols, THOSE at least will never be home defense guns or hunting weapons because far better guns are sitting right next to them in the safe). Slidefire is firmly in the “fun toy” category.

    If you need rapid fire and for various reasons can’t get full-auto, then learn to squeeze the trigger fast while aiming.

  • Nandor

    There’s a good number of youtube videos of people using a bumpfire stock with the RPK to good effect. They were all using the Fostech metal version however. I think the RPK is going to be more difficult than a normal sized AK since this bumpfire method is recoil driven and the larger receiver and barrel assembly weight absorbs more of it.

  • Billson

    It’s McCollum, he’s posted on this site before, but you guys love his content so much you’ll just post it yourselves.

  • David Sharpe

    Can someone enlighten me on what POU means?

    • GearHeadTony

      Philosophy of use

      • David Sharpe

        Ah I see, thanks.

  • Leigh Rich

    BumpFire is same thing but half the price.

  • Ryan Bond

    When you were firing from prone on the first stage you had an nd.

    Maybe practice a little bit of trigger finger control. I think removing your booger hook from inside the trigger gaurd is a good idea, especially when the stock moves and pulls your finger into the trigger.

  • Zebra Dun

    Nice Toy, nothing more. If your concentrating on the function of the weapon your not concentrating on your target.

  • whamprod

    It turned a normally reliable weapon into an unreliable weapon with multiple failures. However, if your mission objective is to die in place in your foxhole, clearing jam after jam while your opponent assaults your position, then this weapon “upgrade” makes a lot of sense.

  • Hank Seiter

    Epic fail I would say. Semi-auto fire is far more accurate and reliable than any slide-fire/bumpfire system, but then I’m preaching to the choir here. Unless one is running a belt-fed off a bipod/tripod, any target past 75 yards should be engaged with semi-auto fire by the average rifleman. Just sayin’.
    Now for suppression fire …

    • The Brigadier

      it is kinda fun bump firing an SKS, a rifle I dislike in semi-auto. In fact I dislike the rifle almost completely except when bump firing it, then its my favorite. It cycles at the correct rate and you can empty a complete mag without a hitch. Still I can fire an AR almost as fast, and I can single fire my M1A a thousand yards with no problem a’tall.
