Ralston Scavenger 6 Multi-Caliber Rifle

At SHOT Show 2016 I stumbled upon the Scavenger 6 Multi-Caliber Rifle from Tim Ralston. It’s a survival rifle that can shoot up to 21 different calibers. If you don’t remember Tim Ralston is the guy who shot himself in the thumb on the Nat Geo show “Doomsday Preppers”, but he’s also the guy behind the X-Caliber system we posted about a while back.

Back to the Scavenger 6 rifle, it was designed for bugging out and survival in mind. Instead of having a rifle that can fire just one caliber the Scavenger 6 can make use of 21 different popular calibers from .22LR all the way up to .308 Winchester. The revolvers six clinders are also barrels, each being 7 inches. Ralston will offer different cylinder barrels he calls a “CB”. His standard CB will fire .22, .22mag, .17 mag, .380, .38spec/.357 magnum, 9mm, .40SW, 10mm, 45acp, .45colt/.410, .44mag, .223, 7.62×39, 7.62×51, .270, 30/06, 5.56, 30/30, .243, .270 and .308.

The Survival CB will shoot .22, 38spec/.357 magnum, 9mm, 45acp, .45colt/.410, and .223. The Hunter CB will shoot .243, .308. 30/06, 30/30, .223 and .45colt/.410. The Battle CB will shoot 5.56, 7.62×39. 30/06, .270, .308 and 7.62×51. Whew, that’s a lot of calibers. While I get the idea behind this firearm it just doesn’t seem all that practical really. I’ll stick to my AR15 or AK47 if I ever had to run to the hills. The Scavenger 6 is still a prototype and no pricing or a release date is know just yet, check out scavengersix.com for more info.

  • Don Ward

    He’s that idjit that blew his thumb off when his plan was to survive an EMP blast by driving his modern Jeep to his “bug out” location?

    Oh HELLLS no!

    • thedonn007


    • Vhyrus

      I don’t know who you’re referring to, but the man in the video definitely has both of his thumbs.

      • JamesRPatrick

        He has 1.5.

        • Tassiebush

          Or as he calls it a midget didget

          • Isaac FluffyWolf Rader

            …Okay, that’s pretty funny.

          • Tassiebush

            Yeah I thought so too. I’d give him minus points for having the accident and referring to it as a misfire but plus points for his calmness and composure around his kids when he did it and for the midget digit line. Plus he paid for it in suffering. I thought his son was awesome for giving him cheek about it.

    • JK

      He’s got brand recognition because he blew half his thumb off, on a crappy TV show.

      • JamesRPatrick

        Hey they put it back on…mostly…

      • Tassiebush

        To give him his due the crovel tool he co developed seems pretty good. I’d actually buy one of those. If he hadn’t shot himself I’d remember him for that.

  • TVOrZ6dw

    I’m always intrigued by multi caliber weapons. I will hold judgement until some demo models are in the hands of testers.

    • Some work well if you pay attention to what is in the manual that says it can shoot.

  • AD

    The fact that you’re basically just swapping barrels and chambers means it’s not that different from a Thompson/Center gun, though being able to swap for a whole cylinder of one caliber or a cylinder with multiple calibers does mean it’s potentially more versatile.

    I kinda like it, though a part of me isn’t happy with the fact that there’s a large and functionally unnecessary fake “barrel” out front.

    If it ever sees the light of day, it could be good for places with restricted gun ownership?

    • Iggy

      I’m not sure if some of the caliber options would prevent it, but couldn’t he just sell it as a pistol with just a short ‘barrel’ as pictured below and *separately* sell a shoulder stock shaped ‘melee weapon’, which is definitely not to be used with the pistol, but if it’s the end of the world I don’t feel the NFA’ll be enforced (unless you’re expecting to be avoiding IRS commando squads whilst you get to your re-purposed grain silo). That’d get rid of the fake barrel at least.

      • Tassiebush

        An impressive set of pepperbox pics there!

        • Raven

          IIRC, that’s actually a Webley tranq dart pistol.

      • Cymond

        “but if it’s the end of the world I don’t feel the NFA’ll be enforced”

        True, but the gun obviously needs to be legal now. Your club stock idea would probably get shut down for constructive intent.

        OTOH, since that long “barrel” doesn’t contact the projectiles and probably isn’t rifled, it would probably be easy to chop off with a common hacksaw post-Apocalypse. I notice that the picture at the top doesn’t have a front sight on the barrel (I can’t see any iron sights, actually).

        • MR

          Kind of what I was thinking. I’d want a longer top rail on mine for more flexibility in mounting optics/buis.

  • Budogunner

    Anybody else uncomfortable with the placement of the foregrip relative to the barrel cylinder gap? The dude shooting himself on TV doesn’t inspire me to give the benefit of a doubt regarding this, especially when you can dump .308 powder down that super short barrel.

    • drambus ambiguous


      The idea is interesting. It reminds me of some of those crazy multi-barrel break action guns from Germany that have 3 or more barrels for hunting various game.

      But this looks like a strange way to do it. Especially the barrel sticking past the barrels. It must be as large as the largest diameter bullet the cylinder can shoot. Meaning the smaller ones gain no benefit from flying through it.

      Combine it all with the grip position and I feel the intention was good, but it wasn’t thought through very well.

      • oldman

        There called drillings.

        • JK

          Where called drillings?

          • oldman

            Drillings are German three barreled long guns usually a riffle barrel under a double barrel s/s shotgun but it can vary.

          • iksnilol

            There’s also “vierlings” which have four barrels.

            To explain: “Drei” means “three”, it is from that that “Drilling” or “Dreiling” comes from. “Vier” means “four” and follows the same theme.

        • Bill

          IIRC, the Luftwaffe even issued them to flight crews as survival guns.

          • Tassiebush

            Yep and if I recall correctly that had a 9.3x74r rifle barrel

      • Budogunner

        I get the extra/fake barrel. That is needed to meet minimum barrel length and overall length requirements so they can make a non-nfa version from the factory. I was just concerned about the fireball rifle calibers might produce so close to the off-hand.

      • iksnilol

        Those “crazy” multi-barrel break actions are called different things after how many barrels there are… also they aren’t crazy, maybe a bit heavy but superpractical if you’ve got some decent earpro.

    • William Elliott

      Taurus solved that with the Circuit Judge. The swing arm has a shield on it that blocks the gap blast. Simple solution would be a similar cup on both sides with venting at the 2:30 and 10:30 position so it doesn’t all blow back into your face

      That and a tunable cylinder gap to minimize it

  • Fred Johnson

    Ummm, so if you fire something like .308 out of this thing . . . won’t the recoil slowly, but surely put a nice bend in the stock extension?

    • Nick

      And possibly a hole in your ear drum. That “barrel” on the end of the revolver is just a tube, far above the diameter of anything it fires. The muzzle blast on this thing could be horrendous with something like 308.

  • MrEllis

    They said I was a chump for looting all the ammo types…

    • DW

      They weigh nothing, so yeah feel free to carry 500 fusion cores on you.

    • M.M.D.C.

      What’s the reference?

      • Bear The Grizzly

        Fallout 4, a video game about survival after a nuclear war.

        • Isaac FluffyWolf Rader

          Though just so we’re clear, Fallout: New Vegas is a better game when it comes to guns. It has a staggeringly large arsenal even before you get to stuff like energy weaponry.

          • Rabies


          • DW

            Fallout NV was obviously developed by gun nuts, you have “change ammo type” key binded by default, reloading benches everywhere, and wasterlanders packing SAA, leverguns and M4gery.

          • iksnilol

            I was disappointed FO4 didn’t keep the reloading and ammo types


          • Isaac FluffyWolf Rader

            Yeah, I know that one of developers – I think it was Avellone? – was a firearms hobbyist. Granted, there’s little hiccups in the caliber, like with a Garand being in .308, but overall excellent. Though imfdb lists them as packing Ruger Vaqueros, but I’m guessing the difference is pretty small. It’s also got the Deckard gun!
            Also, the game managed to make a BFR with a swing-out cylinder. I’m not even mad, that’s pretty cool.

  • Zingbex

    interesting concept. This could eventually become a useful firearm in a
    future iteration. I wonder what the ATF will make of it? Is it a SBR
    because the barrels are only 7″? Or do you add the rifled barrel to the
    unrifled tube in front of it?

    • oldman

      Wondering what the ATF will make of it.

    • Budogunner

      The ATF does not determine barrel length of revolvers based on cylinder length so it makes no sense to do so here. That barrel extension thingie hanging of the front of the frame should be as legit at meeting minimum barrel length as those tac-sol barrels with permanently attached, vented barrel shrouds. Length of the actual rifling is irrelevant.

      There are precedents for this being fine with the GCA and NFA so the ATF ruling against this would screw up many companies.

      • MR

        Agreed, the barrel length should be measured from the muzzle, clear back to the breach face.

  • Edeco

    It’ll be a while if ever ‘fore I trust the lockup to be durable, given the epic frame window.

  • oldman

    Is it me or is that nothing more then an old pepper box revolver mated to a modern revolver. It is a somewhat insetting concept but he missed the obvious it does not take shot shells.

  • It would make a shiat-ton more sense if each cylinder was for 1 caliber each.

    • AD

      The impression I got from what he was saying is that you can either get a whole cylinder for a specific caliber or get mix-n-match cylinders. I might have misunderstood him.

  • Vizzini

    Silly concept.

  • Cal S.

    What, no .50BMG? SMH. For some reason this recalls to mind Brian Regan’s tri-focals sketch (if you don’t know it, look it up). But instead of seeing a bird, a plane, and then Alpha Centauri, you could shoot a squirrel (.22lr), a coyote (.22mag), and then a plane (.30-06)!

  • Trey

    Medusa M-47 gun with a stock, cute if the price is right (it will not be..saddly) would be a nice toy to have.

    A simpler option is of course the Barrel insert system for shotguns. Like X caliber

    • sundancer32

      um, no. EACH of the cylinder holes of the medusa could accommodate all 25 calibers.

      each of this guy’s cylinder holes can only accommodate a single caliber.

      • Trey

        True . I should have been more accurate, it is in the Spirit of the M-47 but different in execution. It is actually more of a verling using revolver / pepperbox tech.

  • LV-426


  • JamesRPatrick

    He should be marketing it as a survival hunting weapon, not a fighting weapon.

    • Vizzini

      It’s not even a survival hunting weapon except in the most esoteric post-apocalyptic scenario. If you were really packing a survival hunting weapon, you’d pick a lightweight weapon in a good general-purpose caliber for the area you expected to be surviving in and would carry as much ammo as reasonable for that weapon.

      Carrying a bunch of super-heavy cylinders that can each only fire one round out of any given caliber is just stupid unless you find yourself scavenging for available ammo as you make your way across post-apocalyptic America.

      You are not Kevin Costner. You will never live in The Postman.

      • JamesRPatrick

        Yeah I wouldn’t want to pack it. Almost makes more sense to make a flintlock muzzle loader that could handle all manner of smokeless powder. Then you could break down any ammo and make it usable.

      • Isaac FluffyWolf Rader

        Why not just get a rifle that fires a really common caliber?

        • iksnilol

          Single shot 7.62x.39 with a 10-12 inch barrel (and appropriately shortened stock) would be pretty handy. Top it with a red dot or lightweight scope and you’re set.

      • Tassiebush

        Must admit that it seems way easier to hoard something that’s cheap and light.

  • iksnilol

    Problem is that you’ve got 6 different cartridges for each cylinder.

    So if you only have one caliber you essentially have a very heavy singleshot.

    • Single-caliber cylinders are also available for any of the calibers listed in the article.

      • iksnilol

        That makes it more useful. Still, wouldn’t something like a KelTec SU16 be more useful? Would weigh similar, have better range and would be much more comfortable. I mean, it has 7 inch barrels, that’s pretty weak IMO.

        That whole X-caliber thing seemed way more handy/lighter to me.

        • Tim started out by telling me (it’s my video above, btw, and I definitely appreciate TFB sharing it) that he received tons of feedback from people saying they love the X-Caliber but that he needs to invent a multi-shot version of it. That’s what he was going for here. 6 shots of any one caliber in a single CB or 6 shots of 6 different calibers in one of the three multi-cal CBs. Get the single-caliber one(s) in whatever caliber(s) it is that you’re well-stocked on and would bug out with, then get one or two or all of the multi-caliber CBs so you can use whatever ammo you scavenge during your TEOTWAWKI adventures.

  • I don’t like the placement of that cylinder gap.

    • Don Ward

      Because everyone needs to have their thumb blown off, that’s why!

  • Patrick K Martin

    They need to bring back the M47 Medusa revolver or maybe just a cylinder conversion for the Ruger GP100

    • William Elliott

      either that or S&W needs to offer their .460 with the full moon clip conversion…
      .45 GAP, .45 ACP, .45 Auto Rim, .460 Rowland, .45 Colt, .454 Casull, .45 Win Mag, .460 S&W, and .45 Raptor all out of the same revolver…just a thought.

  • Bill

    I’ll never be able to watch “Christmas Story” again without transposing “You’ll shoot your thumb off” for “You’ll shoot your eye out.”

    • Tassiebush

      I double dog dare someone to hold it without the vertical foregrip ;p

  • Southpaw89

    So its basically a pepperbox with a stock and a barrel extension, not exactly new, just an old idea implemented differently. Personally I’d prefer to see a .308 bore revolving rifle that could take anything from a .32acp up to 30-06, depending on the cylinder used, keeping the advantages of a useful full length barrel, just limiting yourself to something 30 caliber, and considering how many options are out there that’s not much of a limit. Also being less ugly couldn’t hurt. I’m actually not sure this design even conforms with barrel length restrictions, I believe with revolvers the cylinder is not included in barrel length.

    • AD

      I like that idea, between 300 blackout, 308, 7.63×39, 30-06 etc. you’re covering some of the most common calibers around.

    • Tassiebush

      If single shot on a budget was okay then I reckon mcace chamber adapters on a 3006 bolt action rifle would do that for you.

  • Tassiebush

    It’d be interesting to see how much this weighs compared to the x calibre set plus the shotgun to host it. It’s possibly lighter but at the cost of no 12gauge. I imagine that there are some significant variations in zero between barrels in the “CB”. It’d probably be best used with one cartridge until that supply was exhausted.
    I might not want one but kudos to him for making one for those who might.

  • DIR911911 .

    enough calibers to shoot off all his digits and still have one for the dome 🙂

  • DIR911911 .

    different calibers on the same cylinder? looks like an accident(lawsuit) waiting to happen.

  • Blake

    How is this better than a sack full of TC Contender barrels?

  • Paul J

    This is just stupid and dangerous. They place a “front” grip right in the cylinder gap and put a faux barrel in front of it for no reasons. I would never trust a company that announce a product without even a prototype.

  • William Elliott

    heh, I actually built a .50 Beowulf replica of that rifle from NV…that was fun]

    • Isaac FluffyWolf Rader

      That… sounds AWESOME.

  • Secundius

    My perception was a Firearm with a Single Caliber Cylinder with Chamber Inserts, and NOT a Cylinder with SIX DIFFERENT CALIBERS: .22LR, .38Spc/.357Mag, .45Colt/.410-Ga., .223Rem, 9-Mil, and .45ACP…
