ATI Releases .410 Gauge AR-15 Shotgun – SHOT Show 2017

ATI released their polymer OMNI rifle a few years back, and now they are introducing another caliber conversion: .410 gauge shotgun shells.

The only real change is the upper receiver and bolt assembly (which wasn’t installed for the gun at the show). ATI is also producing their own line of five-round and twenty-round magazines for the project. MSRP on the whole package is about $650.

    An answer to a question never asked.

    1. avatar GlocksRock says:

      Sorry, but the deadline to enter the contest for dumbest AR at SHOT has already closed.

      Maybe next year.

    2. avatar Curtis in IL says:

      The question asked was: Can I get a .410 shotgun with a 20 round capacity?

      This is the answer.
      So, for whatever you would use a .410 shotgun for (squirrels, snakes, varmints at close range, two-legged predators), this is all that, and more.

      1. avatar Frank in VA says:

        Remember when Indiana Jones was dropped in that pit of snakes in Raiders? This might be the ideal gun for that scenario. Other than that, I got nothin.

        1. avatar Sunshine_Shooter says:

          What about a pit of squirrels? I bet you’d feel real dumb if you fell into a pit of squirrels and didn’t have this gun!

        2. avatar Frank in VA says:

          Good point. But I think if I ever get dropped in a pit of squirrels, it’s pretty much over.

    3. avatar Jonathan - Houston says:

      I’d be concerned about feeding reliability of the magazine, but otherwise it seems like a potentially successful marruage of AR-15 platform and its flexibility, with a shotgun’s ammunition and its variety.

      A shotgun offers answer to a lot of questions, what with its bird and buck shot loads, and slugs. A quarter ounce slug is about, what, twice the weight of a 55 grain .223 round? Accuracy and range may have to make compromises, but for the heavier projectile and particular application, that may be worth it.

      Seems like a viable firearm, if the magazines work well, but that’s a big if.

    4. avatar Rad Man says:

      Just because you can doesn’t mean you should.

  2. avatar Sian says:

    Dunno about you but I think a 20rd .410 would be fun as heck, and useful besides.

    Will it still be able to fire .45 Colt? That’s giving me Ideas.

    1. avatar Buzz Word says:

      …. would be great for old folks, women and the disabled to fight off multiple home invaders too: 20 rounds means possibly not having to reload during the encounter, a big plus.

      1. avatar GlocksRock says:

        Yea I heard that ATI makes a wheelchair/walker mounting solution and Jitterbug is working on a oversized trigger.

        1. avatar Pope Gray says:

          HA! If I was drinking something, it would have been all over my screen.

      2. avatar Big Bill says:

        When I read the article, I was thinking the same thing; this could actually be a viable HD gun.
        There are a lot of people who swear by the AR platform for HD; myself, I think a shotgun is far superior (don’t, just don’t. Neither of us would win such an argument.).
        This is obviously a melding of both. Make fun of it all you want, but a slug out of this is just as devastating as a .223, without the overpenetration problems. (Remember, we aren’t talking 200-300 yards, we’re talking 10, tops.)
        If the AR platform is good for a rifle or pistol bullet, why not for a shotgun? It certainly isn’t the first that has the same basic configuration. Being a .410 isn’t really a drawback for HD. While it doesn’t pack the same punch as a 12 or 20 gauge, it’s certainly nothing to sneeze at with proper loads. And it has the plus of answering one of the biggest drawbacks of traditional shotguns: ammo capacity.
        A solution looking for a problem? Hardly. A melding of two different platforms to make a good system seems like a good idea to me.

    2. avatar Vhyrus says:

      a .45 colt AR would be an excellent poor mans 458 socom.

    3. avatar Paul says:

      Magazine fed, 20 round capacity, Alternate rounds of .410 and .45 Long Colt and you have a tool suitable for the apocalypse.

    4. avatar Cloudbuster says:

      Will it still be able to fire .45 Colt? That’s giving me Ideas.

      What’s the point? Just go buy a .45 ACP carbine.

  3. avatar Buzz Word says:

    This is great for women and old folks who need something ergonomically sound, that doesn’t kick all that much and that won’t penetrate too much into neighboring houses or apartments. I hope this gun is durable and reliable. If so, I think it will fill an important niche.

    1. avatar bLoving says:

      As stated before: an answer to an un-asked question. The 5.56mm already has almost no recoil and in a light 45 grain loading, preferrably a ballistic tip of some flavor, has less wall penetration than most handguns. So why change to a shotshell then? Shot spread? At close, in-the-house distances?
      This is one of those “just because I can”-type guns.
      That said; sure, knock yourself out there dudes.

      1. avatar Ral says:

        Ever fired a 5.56 inside a building……….it ain’t pretty. Beyond the concussion and flash rendering your hearing and vision useless temporarily you most certainly will lose a degree of hearing permanently with a nice steady ring in your ears forevermore.

  4. avatar CTstooge says:

    Squirrels worldwide just felt a great disturbance in the Force.

    1. avatar Walter, not The Dude says:




  5. avatar Nanashi says:

    If the lower is untouched, will they sell an upper separately?

    1. avatar Trollololol says:

      Talked to them at Shot and there isn’t plans to sell it separately.

  6. avatar Capybara says:

    What’s next, a .51 muzzle loading, black powder AR?

    1. avatar ColdNorth says:

      CMMG has you covered. .50 black powder muzzleloading upper, 20 inch barrel.

  7. avatar Kit says:

    Wouldn’t this be .410 bore, not .410 gauge?

    1. avatar Curtis in IL says:

      Yes. Yes, it would.

    2. avatar Jeff says:

      Yep. That would be the truth about .410 guns.

  8. avatar Jeff O. says:

    Oh. My. Gosh.

    This sounds like so much fun!

  9. avatar Texheim says:

    Imagine this thing with the echo trigger in it…

  10. avatar Defens says:

    Perfect for introducing FUDDs to the MSR!! “Be wery wery quiet! I’m hunting tiny ducks!”

    “Widdle wabbit season!”
    “Pygmy duck season!”
    “You’re deplorable….”

  11. avatar Nick says:

    Wouldn’t this need to be on an AR-10 lower? Seems the shells would be too long for standard AR-15 mag length unless you had to use some super short ones.

    1. avatar B says:

      .410 is 2″, 2.5″, and 3″. 5.56 is 2.26″ so short shells should fit. Incidentally, Lehigh .45 Maximum Expansion is 1.9 OAL so it should chamber in this.

      1. avatar Nick says:

        Yeah, but how many actually make 2″ shells? It’s not something I ever recall seeing (though admittedly I’m not a fan of the .410)

        I know Aquila made some ridiculously short shells for 12ga, but it seems like this would’ve been better suited on an AR-10 lower to allow better use of calibers load options. They’re already limited as is compared to other shotshell calibers.

  12. avatar Jeff K says:

    Actually sounds like an interesting gun. Now if only the price of .410 ammo was more reasonable.

  13. avatar B says:

    Can you shoot Lehigh Defense Maximum Expansion out of this sucker? 20 rounds of copper broadheads that expand to almost 2″ flying at probably 1,500 fps sounds like a bad time for any intruders.

    1. avatar Sabrewolfe says:

      Sadly, probably not. I’m sure this is a smooth bore barrel, considering it’s being marketed as an AR shotgun. Rifling the barrel doesn’t make much sense, under the circumstances. Which is too bad. Being able to send a hail of those monsters at a home invader(s) would be lovely.

      1. avatar Eric in Oregon says:

        Even if it’s a smooth bore (which I agree would make the most sense), I’d be willing to bet that it’d be just dandy for shooting 45 at inside-the-house range. Probably even longer distances – think slugs, which can be reasonably accurate out to 100 yards without too much effort.

        1. avatar Kapeltam says:

          I think it would come down to what size choke is used. if it is too tight, you risk destroying the gun. It would have to be .452″, which is bigger than even typical cylinder choke dimensions for a .410 bore.

        2. avatar Sian says:

          Rifled choke tube could help.

  14. avatar Mike Betts says:

    At last! Somebody has finally invented a practical dove hunting gun where you can burn through cases of shells even faster.

    1. avatar Dyspeptic Gunsmith says:

      Better not be caught hunting doves with this gun.

      You can’t have more than a three-round capability before reloading in a dove shotgun.

      1. avatar Lance F says:

        Yeah! But clays, 5 stand, now I have a chance. Give it a rifled barrel and I could hunt deer with it, WA has shot gun only areas, but pistol caliber rifles are not legal.

    2. avatar matty 9 says:

      No need, I can blow away 3 or 4 boxes of 12 Ga with a double barrel shotgun and bring home my 8 birds.

      damn, those little birds cost a lot!

  15. avatar VerendusAudeo says:

    If the upper worked with a Fostech Echo trigger, this thing would be fun as hell to shoot.

  16. avatar Dr_elusive says:

    If it would shoot .45 Colt, it might be kinda cool. Can’t think of a reason to shoot 410 out of an AR though

    1. avatar Jeff K says:

      If you could get bulk .410 for the same price as 12 gauge, it would be a hoot. Otherwise too expensive.

      1. avatar SouthernPhantom says:

        All things are possible through reloading.

        Okay, almost all.

  17. avatar Geoff says:

    But I am only allowed THREE ROUNDS in a shotgun for hunting.

  18. avatar strych9 says:

    My first thought is “Slidefire Stock”. Granny can really lay out the whoopass on the home invaders with that.

  19. avatar MarkF says:

    I cannot imagine any reason to own this, but damn, I want one! Why? ‘Murica, that’s why.

  20. avatar Bfitts says:

    This sounds like a good gun for thick brush hog hunting. Load up on 000 buck shot and kill the little piggies.

    Surprised no one has mentioned this yet.

    1. avatar ACP_arms says:

      A .410 shotgun for hogs?

      I can see using a 12 or 20, but .410… nope.

      1. avatar Vhyrus says:

        Well, remember, you have 20 rounds. I am pretty sure 5 or 6 in quick succession would lay down any normal size pig.

  21. avatar Freds says:

    The bird hunting gun you load on Sunday and shoot all week!

  22. avatar Mr Bad Example says:

    We live in crowded apartments and my 4’10, petite, pregnant wife would certainly make good use of 20 rounds of .410 buckshot.

  23. avatar S.CROCK says:

    This may seem dumb but I actually want one. And 20 rounds of .410 buck is no slouch. Quick follow up shots and you might still have some hearing after shooting this in a hallway. And the fun factor would be worth it for me! Reliability is my only concern.

  24. avatar Me. K says:

    It’s a different version of an AR, I am now required by OCD to buy it. Crap.

  25. avatar Ed says:

    I love using a .410 for trap. Adds that little extra level of difficulty

  26. avatar Ozzallos says:

    People are all ‘answer to question never asked’, but if you can’t think of a use for a 20 round AR that can fire anything from light shot to self defense buck and .45 slugs, you’re not trying hard enough. .410 isn’t exactly cheap, but people spend more for less utility, so whatever.

    1. avatar Salty says:

      This is a .410 BORE. That’s .040. DIFFERENT (ie smaller ) than a .452 45 colt slug. That extra 40 thou is prob gonna cause Darwin to come knocking on your door. The diff tween this and a judge is a judge happens to have a ,450 bore, and 410 chambering, this has .410 chambering AND bore…. Details!

      They used to have one of these as just an upper. Reliability/craftsmanship were lacking. They took off market, sounds like they spent 5-7 years refining it, will be fun. Don’t like it? Easily solved, don’t buy it!

  27. avatar Fight islam Now says:

    Is it available? Is it NFA? Does it fall under atf rule 94-7?

  28. avatar Fight islam Now says:

    Just spoke to ATI- NFA applies.

    This may be the best time ever to get abolishing GCA 68 in front of the president. WE need
    To enlist the presidents sons to carry the message to the dinner table.

  29. avatar Otto von Siegfried says:

    Companion piece for a Taurus Judge owner?

  30. avatar James69 says:

    About oh crap… 8 years ago somebody was building these. I ordered one but never got it. Now build this for my AR pistol and I’m in. Shooting Hornady critical defense rounds (41 cal hollow point and 2 buckshot) would be cool.

  31. avatar JB1000 says:

    Speed Skeet? 20 clays over a minute and you have to run between the positions?

  32. avatar Jack says:

    Funny thing is, they have been working on this since the last shot show. And it sounds like they still don’t have it figured out.

  33. avatar Robert W. says:

    Not sure why all the criticism. According to GunsAmerica there are 53 calibers that can be fired off the AR 15 or AR 10 platform so why criticism of the .410? And considering they range from 22LR to .50 Beowulf the .410 not only is nicely in the middle but has a wide range of options from slugs to salt. Would not be my go to choice but certainly not any more absurd than the AR 57 upper firing 5.7x28mm round….which for the record is a hoot. If money and marriage weren’t an issue wouldn’t mind adding this to my collection.

  34. avatar The Lil Guard says:

    Where can i get this exact set up??

  35. avatar Chris T in KY says:

    The 5.56mm fan boys will never understand choice.
