The standard breaching shotgun is the Master Key, a tiny Remington 870 shotgun modified by Knight’s Armament Company to fit on the front end of an AR-15 or M-16 rifle. It works, but it’s heavy and racking the action requires you to take your hand off the shotgun. Crye Precision think they have a solution that would let the door kicker fire multiple rounds into a door while still having a finger on the trigger of the rifle . . .

The shotgun has a rotating 6-round magazine that is detachable, so you can reload it on the fly and very quickly. The gun has a solid single stage trigger, and is semi-automatic to make the operator’s life easier. There’s also a convenient blast shield on the front of the magazine to keep the blast from screwing up their hand.

Oh, and they have a standalone version. Which looks BAD ASS!

  1. Cool but can you take the cylinder and set it up as a landmine like the Pancor Jackhammer? No? Nice but I’ll pass.

      • What about AC-130s, apaches, RWS weapon systems, or just in general any weapon in the US arsenal that protects its users and gives almost no chance to the target. Mines and IEDs are a weapon that works. If we wanted to be fair we would still be squaring off in open fields with muskets.

        • Land mines are the weapons of scum. In real-world usage, they maim and kill children far more often than they kill the enemy.

      • There is no such thing as a cowards weapon in war. We use crap all the time that gives our enemies no chance to fight back, why we should we say they are cowards for using what they have. That is war, adapt and overcome, which ever side can do this better wins.

        • How can I say this in a nice way? If you aren’t pulling the trigger and seeing a man go down, I will probably call you a coward.

          I have seen too many innocent people maimed/killed by explosives to condone their use.

        • You want to trot that line out to the relatives of the brave men who manned American bombers to fly daylight raids into the heart of Nazi Germany before they had even as much as a fighter escort?

          I’m sure you will immediately want to qualify your assertion, sir.

        • @Lolinski
          I guess that’s a fair opinion, but I think most practical thinkers would disagree with you. Including me.

        • “If you aren’t pulling the trigger and seeing a man go down, I will probably call you a coward.”

          “If you aren’t pulling face to face and seeing your opponent’s eyes as you chop him down, I will probably call you a coward.” – Japanese Samurai, immediately before being dropped by a man with a muzzle loading musket.

          Call m any fvcking thing you want, I still win.

        • lolinski is from the land of SAABs, which ironically makes a lot of our explosives. AT-4 anyone?

        • Killing your enemies from afar when you can is not cowardly, it’s just wise.

          It’s also doubly efficient, because when the target cannot shoot back (or at least where they know it will never hurt the person operating the gadget that’s raining fire on them), their morale also plummets. People hate not being able to hurt back.

          Which is, again, good. You want your enemies to be demoralized, panicked, and afraid of your superiority. They won’t pick fights with you then.

        • Paul T. McCain: You’re right. Those were brave men to firebomb German civilians, so that Stalin could occupy the Baltic States, Poland, Yugoslavia, and East Germany.

      • Claymores have 2 modes, controlled and uncontrolled. Only the uncontrolled mode, (trip wire,) legally qualifies as a booby trap. Controlled functions as a remote controlled shotgun blast on a much larger scale. There is no practical difference between it and direct fire, your argument is invalid

      • Dude your in no position to despise landmines lol I feel like you probably have little to no experience with them. Its a tactical impliment only an idiot wouldn’t use everything they can to their advantage

      • Basically, yes. But my sense of beauty could be suspect. I think Mosin Nagants are cool. To me the Glock is ugly. But it works and works well. It’s still, in my opinion, ugly.

        As for tacticool. Well, there’s a whole lot of wannabe operators hanging around gun forums. I guess it makes sense for a company to take their money. It’s not like this stuff will ever go anywhere but the range and the safe.

        • I think Mosin Nagants are cool.

          I may be the world’s biggest fan of Mosin rifles and carbines, but they’re about as attractive as Lyudmila Pavlichenko.

        • I shouldn’t mention then that I keep a poster of her taped to the ceiling above my bed?

          @lolinski, try saltpeter instead. It works just as well and it doesn’t cause nightmares.

        • Cool =/= beauty. Mosins aren’t cool, but they are beautiful in their way. This is not beautiful, but it is cool.

  2. Why does that thing remind me so much of the ED-309 from the original robocop? That one didn’t work out so well, but this thing looks flipping AWESOME. Didn’t the M26 MASS already fill the void on this though?

    • If I’m not mistaken, that would fall under SBS, the rifle would get registered as the host, and since it is a rotating cylindrical design, a destructive device? Street sweeper was the same basic principle, or am I wrong?

      • Revolving shotguns are not automagically DD’s. The Streetsweeper was, yes, but there’s a couple of cowboy designs floating around that aren’t. If you bought it as the standalone, then it doesn’t look to be an SBS either. The underbarrel one probably uses a shorter barrel – but I *think* you can count the AR as part of the OAL (it’s the shotgun’s stock, right?), so if you’re willing to take “completely unwieldy for 400”, then you might get away with no stamps. Anyone seen an FTB letter on the subject?

  3. How about just welding a couple of GG&G picatinny clamps to the barrel of a Rossi Circuit Judge, sans buttstock, and mounting that? Not that .410 would be a preferred breaching round….

    • Description on another site says that a commercial version will be made available with a 22 inch barrel. That would put the OAL and barrel length outside NFA. Police/mil versions to be available by end of this year and commercial version sometime after that. I’m not holding my breath for either time-line.

  4. I like it, sadly I live in the **** state of California so any “shotgun with a rotating cylinder” is banned as an “assault weapon”

  5. Damn, this may be the most interesting firearm at SHOT. It’s both new and cool. Any word on availability to civilians and when it will be hitting the market?

  6. I want one. Sadly its illegal in Norway (damn you California!).

    Do they intend on making a full auto version? With 10 or 20 round drums? C’mon, this is an opportunity to revive the Jackhammer.

  7. Is it semiauto or is it a revolving chamber? How easy is it to swap out cylinders? It looks like a cool concept for a limited use.

    • Exactly what I was thinking. This is what they will use when they serve that no knock warrant on your house at three am, because you have guns.
      No other reason for it to exist. Not defensive.

  8. I’m on the fence.

    I see no use for the stand alone version other than the (uber)cool factor but I approve of the ingenuity and hope they sell bunches.

  9. Question is how does it transfer? AOW I imagine for the attachment ($5 transfer tax), but then might it become a SBS if you attach it to an AR (which would act as a stock).

    What about buying it a standalone and then detach it from the stock and to a rifle or SBR. What is it now? NFA is an incredibly stupid law.

  10. Anybody got a clue how you are suppose to hold you hand when pulling the trigger on the shortbarrel on the 10upper. Looks uncomfortable at the least.

    • I’ve seen this on other sites, and there is a pistol grip that can be attached to the shotgun when it is used as a masterkey.

  11. Crye Precision, makers of stuff other than multicam, but yea youll never see it out in the real world so we’ll just stick to “makers of Multicam!”

    Shot show does NOT qualify as in the real world 🙂

  12. Right off the bat it matches a topped-up stock 870 for capacity. How fast can you swap cylinders, and how much do spare cylinders cost? Because even if it’s slower than an untrained AK reload it will still beat a tube-fed shotgun for reload speed. Forget breeching doors. If this thing is done right, it could be the next big “social” shotgun thing. Maybe scale the thing up a bit for an 8 round cylinder and drop the under-barrel option in a Mk2 version?
