AT-14: The .410 AR-15 Shotgun

Yes, you did you the title correctly. American Tactical Imports are bringing the Safir Arms T-14 stateside and calling it the AT-14.

At-14
T-14 Classic

Now you are probably asking yourself why would someone want such a gun? When I first learnt about the T-14 a few months ago I asked the same question. The T-14 is very popular in Europe. Many countries, including Turkey where the T-14 is manufactured, either ban semi-automatic rifles or make it hard to own one. This gun is the closest thing the average citizen can get to owning an AR-15.

So why is ATI bringing them to the USA where AR-15s are plentiful? I wondered about this myself. First of all they could be a popular hunting arm for AR-15 enthusiast for use in shotgun only hunting areas (I don’t hunt with a shotgun, so correct me if I am wrong). Ed Friedman made a good point that with the new self defense .410 ammunition from Federal this gun could make a good self defense weapon when over penetration is a concern. A .410 slug should give similar performance to a .357 Magnum.

The ATI advertisement.

Guns.ru describe the gas system as follows:

The gas system utilizes annual (ring-type) short-stroke gas piston, located around the barrel

The gun can be seen in action in this youtube video:

ATI will be importing the Classic model and the Compact model. Both feature a A2 carry handle style upper receiver, fixed stock and 20″ barrel. The only different is the length of the handguard.

AT-14 Compact

According to Ed a 5 round and 15 round magazine will be available. I have read that AR-15 magazines can be converted to hold 10 .410 rounds. Ed hopes to review the shotgun in an upcoming issue of Guns and Hunting.

UPDATE: The MSRP is $979 and dealer price is $800. They should be available shortly (thanks War Wolf and Todd for the info).

    If somebody were to make rimless .410, this could be very cool. That way you could double stack the mag and easily have 25-30 rd mags. Come to think of it, why has no one ever made rimless shotgun shells (aside from pistol cal shotshells)?

  2. Peteon 26 Jan 2009 at 11:37 pm link comment

    For instance, if somebody made rimless 12GA, then Saiga 12’s would instantly become WAYYY more practicable.

  3. Daniel E. Watterson 27 Jan 2009 at 2:52 am link comment

    If shotshells were rimless, they wouldn’t be able to maintain proper headspace. Remember, loaded shotshells are shorter than the chamber. The difference in chamber length allows the crimped hull to unfold.

    At best, you could hope for a belted shotshell, instead of a rim. While there wouldn’t be much difference in width, at least then you would have fewer issues with rims interlocking.

  4. Donon 27 Jan 2009 at 3:20 am link comment

    I was never a huge fan of the AR (big M14 fan), though this thing is really cool. It’s a shame it’s a smooth bore. A sabot slug would be great in that thing. So would shooting trap.

  5. ZerCoolon 27 Jan 2009 at 3:51 am link comment

    At least here in NY, the .410 is not legal for large game hunting – DEC regs require a minimum of 20ga.

    While it would be theoretically possible to hunt birds or small game with the .410, I don’t see the AR as being the ideal platform for that. Accurate shotgunning is about smooth swing and follow-through… I don’t find that with an AR.

  7. R.A.W.on 27 Jan 2009 at 5:14 am link comment

    Interesting choice; going with the annular piston. A few other designs, like the VZ-52 and the Steyr ACR candidate also use a piston that surrounds the barrel like that.

  8. UraniumHeadon 27 Jan 2009 at 5:14 am link comment

    Rimless shotgun shells are unfeasible because all shotgun shells are shorter than their stated length when unfired. This is because the end of the the shell has either a star crimp (for shot charges) or a roll crimp (for slugs) to contain the payload in the cartridge. For example, a 2.75in shell is more like 2.5in before firing. With no fixed length there is no way to headspace the shell without a rim.

  9. 22lron 27 Jan 2009 at 5:21 am link comment

    Ok a definite buy.

  10. AughtSixon 27 Jan 2009 at 5:38 am link comment

    I believe the shell headspaces on the rim. The chamber is long enough for the front of the shell to unfold, so I don’t think it could headspace there. So, take away the rim, and it won’t work. Not insurmountable, but there’s no shoulder to headspace on, and you need clearance at the mouth, headspacing there would be problematic.

    Wolfwood, I am not sure about that. I wondered myself.

  17. Billllon 27 Jan 2009 at 1:33 pm link comment

    If one were to make a rimless shotgun shell, what’s to keep you from headspacing on the brass, and treat the front like a big plastic bullet? Make the brass a tad larger to keep it out of conventional shotguns, and the rim on the conventional shell will keep the new gun from going into battery with the old ammo.

  18. Justthisguyon 27 Jan 2009 at 2:32 pm link comment

    Years ago, I looked at my copy of Cartridges of the World, and other references, and decided that a sawn-off and somewhat blown-out 20mm case would make an excellent rimless 12-gauge case. Failing that, we still have the Saiga 12. There are drum magazines available for it. At the moment.

  19. Steveon 27 Jan 2009 at 4:13 pm link comment

    Justthisguy, the problem is cost :( No one would buy them because the cost of the brass. One of the problems with using a stacked magazine (as opposed to tube) with plastic shot shells is that if they stay in there long enough the cases can deform. Brass cases fix this problem but are very expensive, which is why you never see brass 12 guage, although they are available. Brass 12 guage can be seen in that western staring Russel Crow playing the good-guy-bandit (I forget the name).

  20. jdun1911on 27 Jan 2009 at 6:04 pm link comment

    I’m not familiar with shotguns but if the 410 can fit into the magwell (or any cartridge), you can use a standard AR15 lower.

  21. Steveon 27 Jan 2009 at 6:18 pm link comment

    jdun1911, that depends on the upper design. It is an AR in spirit but I am not sure how much of an AR it is in practice. Standard AR magazine can be modified to take the .410 using a dremel tool so presumably they fit in the mag well.

  22. jdun1911on 27 Jan 2009 at 6:46 pm link comment

    It would be foolish of them to not use the standard AR15 lower if that is the case.

    All websites about Safir T14 and wild boar hunting;I experienced it at range a friend of mine has one.Use federal ammo instead of cheap imitations like zuber spreads,ital 410s are good federal superb,do not use ammos other than slug,so this is a wild boar rifle not for birds. http://www.metacafe.com/watch/2344459//,like every semiauto even 0,5 gr more blackpowder makes a change,clean rifle at every 100 shots,if you are a shooter clean before storage,factory says every 200.Low recoil,comes with a beatiful pelican case,price in Turkey around 1000 USD has 4 different models.Factory is at Umraniye Istanbul;owners are ex special forces officers and NCOs who relied on M4s for their lives in their entire carriers,so the result was Safir,lovely to think all USA market M4 accessories suit them well,pointers,scopes,you name it.Wild boar shot claims differ alot,but 287 meter claim I saw on the web,happens like this I figure first shot before 100 mts,second when target tries running,second shot distances vary but do not take risks I say above are the results.Think of your shot buddy,dog and yourself.I hope laws wont change letting many people enjoys and owns this lovely rifle.I also ask myself why not M14 410 slug firing models for Safir,which will sell just fine.
    Lately I saw taurus has a 410 firing revolver?410 s on the run?

    I saw one of these at the SHOT Show. It’s an interesting idea and really a pretty good one for dealing with snakes and varmints(big and small) in the woods. Of course I have a Saiga 20ga (and wish I had bought the .420 version back when they were <$200) so I may be a little prejudice.

I have the Saiga line of shotguns but this is totally different, not better just different. The ease at acquiring clay pidgeons and ground targets is amazing. What a great hunting gun this is going to turn out to be and the cool factor is off the charts.

    Hey fellas … here is a place to get metallic brass. It can be reloaded. I have some metallic brass .410 brass from some Russian shells,but they have BOXER primers and are a pain to reload.These have the Berdan peimer pokeys that are eat to reload,,….Dave…..PS…I am having a hard time attachingbut they are at MIDWAYUSA firearms supplies site and are bags of 25 empty brass fully metallic shells in lots of 25. I am a .410 “BORE” nut too.

  37. Keith Applegateon 08 Mar 2009 at 4:38 am link comment

    Umm, D.S. you have that bass-ackwards. Those Russian shotshells are Berdan primed. The Magtech brass from Midway is Boxer primed and, like all of the older US produced all brass shotshells, are designed to be used with PISTOL primers not rifle primers.

    Boxer primers have a self contained anvil and the primer pocket in the case has a single flash hole. Just about every cartridge produced in the USA uses a Boxer primer as they make it extremely easy to deprime and reprime a cartridge case.

    It’s Berdan primers that feature the anvil machined (stamped) into the primer pocket and multiple flash holes. Berdan primers are heavily favored in Europe where civilian reloading is nearly unheard of. While you can reload Berdan cases it is a very laborous procedure an the primers themselves are nearly impossible to find in America.

    The irony of it all is that the Boxer primer so popular in the US was invented by an Englishman named Edward Boxer (of course) while the Berdan primer which is rarely encountered in US produced ammunition had been developed a few years earlier by Colonel Hiram Berdan, famous for his “Berdan’s Sharpshooters” of the War Between The States, who was an American.

    So, how does this fine looking weapon compare with the Saiga 410? I have a Saiga and have found it to be very reliable, based on the AK47, basically the best thing Russia ever built, but I came across this gun and I like the look.

    What length shells can it accept and how reliable is it? The Saiga fires 3” shells but there is a special magazine that allows for 2.5” rounds to be fired properly. I use the Winchester 3” 000 Bucks as well as the Silver Bear zinc powdered metal shell sabots.

    Thanks.

  39. Dave Stanleyon 14 Mar 2009 at 1:46 am link comment

    Thank you for helping me out with the primer situation. I had just came home from the dentists office where I had two teeth pulled. I had broken one and had to have a little emergency surgery so my spelling was off by a long shot. The primer thing I honestly just had backasswards. I shoot a lot of the Russian GOLDEN BEAR ammo that comes in the two and three quarter inch length brass shell. It holds 5 pellets. Their web site is http://www.bearammo.com…In my hometown it comes in a little purple box with 5 shotshells for $4. Once in a while I have to fire the same shell twice in my single shot H&R .410 ,but it always fires the second whack with the hammer. I think the primers might be a little thick skinned,but I find this is an awesome round. A 15 shot mag could send 75 good sized pellets down range in no time. I know there are many arm chair warriors that will dis agree,but I would love to have a Safir loaded with a mag of Bear Ammo for a home defense weapon. I know of NO thief that would try and stand in the doorway and argue with this gun blasting away at him. If he did I doubt if he would be there long.

    i didnt even know these were already being important until i saw one for sale at a local firearms dealer. not sure how much they wanted because the one they had was already sold so i didnt bother asking the price. i dont really know much about the .410 as i dont own any shotguns in that bore. but im thinking of purchasing one just because it looks nice. and the best part is, its legal up here in NY so long as it dont have the collapsible stock and the magazine capacity is not more then 10 (im not sure about 10 as it may be 5 for shotguns)

    I have both the Saiga 410 and the Safir T14. The saiga will shoot anything while the Safir is a little picky, especially with shotshells.

    Manzahn
    Try a different brand of ammo. Also make sure the Safir is clean and well lubricated. While the AK platform will work under any condition the AR platform needs to be clean and well lubricated. If you continue to have problems after this contact ATI. They support there other products very well and I would expect the same with the Safir.

    I bought one of these a couple of weeks back, the first one I saw/held. I have already posted my initial impressions and experiences on AR15.COM. I want to give it a much better workout with many more loads before making any pronouncements, but I like it so far. It seemed to feed the smooth-shell rounds just fine, but hung up every 2-3 rounds with teh ribbed ones. I will tell you that the sight of busting clays with an “AR” was almost worth the price of admission by itself!

    Except .410 slugs are only 90 grains. Use a pistol caliber carbine instead.

  52. Steveon 29 May 2009 at 2:10 pm link comment

    .410 slugs are perform similar to .357 magnum (so I have read online).

  53. Overload in COon 29 May 2009 at 2:52 pm link comment

    I had the same question with regards to a Taurus Judge, which can shoot .410 or .45 Colt.
    A .45 Colt load is a 255gr bullet with a muzzle velocity of 961fps, for a muzzle energy of 523 ft/lbs.
    A .357magnum 158gr JSP muzzle V is 1240fps with 539 ft/lbs
    A .410 slug weighing 90gr muzzle V is 1830fps 651ft/lbs (out of rifle barrel)
    (all stats from wikipedia or winchester)

    So, yes it does have power of a .357 Magnum.

    or you could carry an M1 carbine in .30 carbine. 110gr bullet, 600fps, 880ft/lbs. 15 or 30 shot magazines.

    or a Carbine Conversion Unit for a 1911
    230gr bullet, 830fps, 352ft/lbs (out of a 5″ barrel so speed and energy would be higher) 7,8,10, or 15 round magazines.

    or .44 magnum out of a Ruger 99/44 Deerfield carbine….

    or an M4 .223 AR-15 with rifle rounds!

    I question the use of a rifle (minimum length 26 inches, usually longer) for the tight confines of home defense. I’ve seen TV shows and read articles that talk about home defense with a rifle, so there are those that support it.

    I purchased a 410 T-14 upper and was very excited about it because I hog hunt, and I thought this would be great in the brush, etc. I was told on the phone that it would shoot 3″ shells. I was terribly disappointed when it arrived to find that it will only use 2 3/4″ shells. I am going to keep it, but that does cut my firepower in half.
    I am putting this information out for those who might have the same question. Nowhere on the website does it state what ammo the gun uses.

AR lower, I have purchased a DPMS 223 upper and it works great – A little bit “off” with the rear pin, but a slight tap with hammer and all is well. The T14 only takes 2.5″ shells, but will shoot anything – I prefer 000 . Fun to shoot, has been totally reliable, glad I got a great deal. I checked with Safirarms and ATI and they say 15 round mags ( I think it was 15 ) should be available soon, if not now. Three weeks ago ATI said they were expecting them any day, then they had to quality check and get out to distributors.

    tried two mags and gave up. With the release of the 15round magazines I just went that way. A lot of time tig welding the feed lips in the correct position and fabricating a follower all to no avail.

    Good luck if you choose to pursue it, just seemed more cost effective to buy the ones already out there with higher capacity.

  66. grivon 14 Jan 2010 at 6:41 am link comment

    The comments on the unreliability were widely available when I was interested in the AT-14, so I ended up going with the Saiga .410. I upgraded the compression and the trigger springs and it has NO problem firing 25 round magazine after magazine. The Silver Bear .410 Sabot was actually designed specifically for that gun. There is also a magazine available that allows the use of 2.5 inch shells.

    The Saiga 12 gauge works great too and can handle different length shells in the same 12 round magazine. 2″, 2.5″, 2.75″ and 3″. That’s a lot of flexibility in what type of shell you need.

  67. Mikeon 14 Jan 2010 at 2:47 pm link comment

    25 round saiga magazine for the S410? I have a few of the drums for my S12 and 10 rounders for the S410 but have not seen the S410 25 rounders. My S20 gives me fits with different types of ammo but is reliable with the brands it likes.

    I have not had the issues with the AT 14 that some have had. It shoots very well even using the higher cap magazines. I still find the AT14 in need of some chokes so I can use it effectively for hunting birds.

    Oops, that would be 15 round magazines NOT 25 rounds. Sorry!

    anyone know what happened?
    I ordered a 14 from a gunstore three months ago and they couldnt find one for me, something about Safir sold the design to another company? new factory? or something like that. confusing, all I know is the gun store hated to give my check back to me.
    who is the new company,and when will the gun be available again?

    I just bought an AT-14 upper and mated it to a DPMS lower with a Magpul 1LX50 adjustable stock. I have one question, and a comment that might help some future reader.

    Question: I understand that this gun is ammo sensitive, ie it won’t shoot and cycle just any .410 2 1/2 inch shotshell. What will it shoot well?

    A customer service rep. at ATI told me that I could use any roll-crimp (not star crimp) 2 1/2 inch shotshell and it should work fine. Well, not quite …

    I bought a box of roll-crimped Federal Premium .410 2 1/2 inch buckshot (4 pellets – 000 buck) and they are too long to fit in the magazine (but only by less than 1/16 inch). The box specifies “.410 HANDGUN” (eg Taurus Judge), so that alone may account for the incompatibility.

    Comment: With the set up described above the bolt would not lock in the open position unless I really yanked back on the charge handle. The guy at the gun store from whom I purchased the AT-14 had told me that the gun didn’t lock open, because it was designed to accomodate the .410 shotshells. I’m now pretty sure that is incorrect.

    Instead, the problem turned out to be caused by the Magpul stock. I guess the travel was not great enough for the bolt spring internal to the stock. I switched to a more vanilla stock (ACE LTD) and the problem disappeared. A gentle pull on the charge handle while holding down the bolt catch is now all that is necessary to lock open the bolt.
