ATI Omni Hybrid AR-15 .410 Shotgun – Video Review

YouTube personality, Graham Baates, gives us a video review of the ATI Omni Hybrid AR-15 .410 Shotgun.

USA – -(Ammoland.com)- American Tactical, also known as ATI has been known for doing things a little differently.  From hybrid polymer 1911s to MP-40 look-a-likes their lineup always has something interesting.  Of note has been their continued experimentation with polymer AR lowers.  Now entering their fifth generation, ATI continues to improve on the design and expand the application of modern polymers.

Another enduring endeavor of theirs was to create a true .410 AR upper.  Not just a shotgun that looks like an AR, but an upper and magazine that could be mated to any standard AR-15 lower.  That shotgun is here now in the form of the ATI Omni Hybrid AR-15 .410 Shotgun.  That's a long name, but a descriptive one.

A lot of physics and engineering had to go into the creation of such an upper, but ATI has done it.  Their magazines are limited to 2.5″ shells, but thanks to guns like the Taurus Judge there are plenty of loads available in this size.  They are so available in fact that we were able to find a variety of loads.  Defensive loads, slugs, birdshot, and buckshot were all readily available including the surprisingly affordable options now being sold by ATI.

We wanted to test out the widest variety we could after experiences with other box-magazine-fed shotguns.  It seems that shell-hull makers can't agree on the texture and material that the hulls are made of, and in previous experiences some hulls tended to snag or drag when feeding.  That was not the case with this shotgun.  Another issue addressed by ATI was ensuring that the rimmed rounds would not snag on one another and prevent feeding.

Anyone with .22lr or 7.62x54r experience can empathize.  American Tactical included clear instructions warning of this potential problem and even designed the magazine in a way to let the loader clearly see if they've slipped a rim.

Another clever and brilliantly simple design feature is the inclusion of small windows along the leading edge of the magazine to permit for quick referencing of the round count.

So how did the Omni Hybrid .410 do on the range?  See the range test video and watch every shot.  Count the malfunctions for each load type.

ATI Omni Hybrid AR-15 .410 Shotgun Shooting Impressions

Future testing will include patterning those loads at range, and perhaps attempting some groupings with slugs.  That may prove to be more a test of the ammunition than the shotgun, but will be conducted none the less.  We plan to also swap this upper onto one of our conventional AR-15 lowers.  It should be noted that ATI recommends transferring the buffer and spring from their shotgun when mounting this upper to another lower.  They've done the leg-work and found the right spring and buffer weight.  We didn't experience any trouble loading the magazines by hand, but a speed loader is available.

More information can be found on the product website.  My question to the readers is what would you use this shotgun for?

    The upper wont work on a standard lower, I tried it and the magazines are way too tight, it has a deeper than normal notch on the mag itself that looks to be causing the issue. Other than trying to sand down the mag a bit it doesnt seem to be compatible with regular ar lowers….

    Thanks for the update.
    I have a different upper on the ATI lower now.
    The 410 upper been sitting in a box for a while now.
    Was thinking I should try to sell it, but don’t think anyone would want it if it didn’t fit on a mil spec lower.
    Thanks for trying.

    I’ve had nothing but jams with the 410. Put a 450 Bushmaster upper on it. Problem solved. If someone wants the 410 upper, leave a comment.

    Still having problems with the 15 round mags. They sent me two mags that they ran….flawlessly they said…but still wouldn’t work in my gun. Charles is supposed to send me a “return” but after filling out all the information last week I still haven’t heard from him. Called a couple of times….no Charles(perhaps he was sick or something this week). Try again on Monday. Interesting thought on the feed ramp being rough and perhaps the brass is catching on the lip of it. Might look that over tomorrow. Thanks for the tip!

    I got one for Xmas. I have had nothing but problem after problem. Save your money and don’t buy one. I have sent mine back to Omni multiple times. They have had it more than me.

    What did ATI do to supposedly fix your problem? How long did it take each time you sent it to ATI? I am about to send my gun to ATI to try to solve some of these problems. Everything everyone has mentioned has also happened to me with my gun. I seem to be able to get it to run with ATI ammo, but if I use some buckshot, I get a jam, many times with a double feed. I have bent or pinched so many expensive ammo shells in the process. They generally can’t be reloaded into the magazine… Read more »

    This is how the ammo is getting pinched on the front edge. I think the feeding ramp is catching it.

    Love the Omni .410 BUT having a LOT of trouble with the 15 round mags. Using ATI’s slugs and the gun functions perfectly with the 5 round mag…but switching over the 15 round mags and it’s nothing but jam after jam. Shoots 2-5 rounds then jams. Sometimes doesn’t pick up the top round, leaving the chamber empty..other times(most of the time) bolt stops before getting closed, as if there is too much pressure coming up from the top round in the mag. Talked with ATI….and sent my two 15 rounders back in…received two new 15 rounders…same exact thing. Then tried… Read more »

    Please let us know the outcome of contacting ATI. I was also starting to believe that there was something wrong with my 15 round mags. Definitely, I have a lot less malfunctions with the 5 round mag that came with the gun, compared to the 2-15 round mags I bought later. I too have suspected that the top round in the mag presses too hard against the bolt while sliding forward into battery. I do know this: if I slam the mag into the mag well and go, that’s when I get these malfunctions. If I slam the mag into… Read more »

    Ran 3 mags thru it with 4 different type shells, all good. Was loving it. Then the first shell in mag #4 fired and the bolt would not return to battery. Hung up on the back of the mag. ATI says they have never heard of it occurring. Videos on Youtube show just what I have. So I suspect they are full of it. Charles in customer service said he’d ship me a new mag to try out. He didn’t do it. A week later the girl in customer service said there was no record of my call. (Damn you… Read more »

    I shot my 410 this weekend for the first time.
    Similar problems after 2 – 15 round mags.
    The ATI ammo ran pretty good, but Hornady CD all didn’t feed correctly. Remington defense 000 buck worked ok in 5 round mag, but had problems in my 2 15 round mags.
    Federal premium 000 buck couldn’t even cycle out of any mag. It’s longer than all the rest of the shells.
    I got frustrated and gave up.

    I’ll give it another try once I get some more different ammo. Else, I will be buying a lot of the ATI ammo.

    I’d rather have my Judge for the .410 and I prefer my AR-15 to be 5.56mm, thank you.

    The circuit judge will shoot 45 acp with a special ring to hold the ammo in place. It is a pain in the ass but it works. Mine is the older one from when they first came out. Will NOT shoot 3″ only 2-1/2″

    Perhaps because a 410 was my first shotgun, I am a sucker for a new 410 anything. It would be interesting to see the pattern of shot at various ranges.

    Great review and great videos. I’d really like to see the patterns and groups.
    I’m kinda torn on the cost of 410s and me burning them up in an MSR(S) style weapon but it does park my interest.

    Is that just for the upper? Or is that price for the whole rifle?

    I find that the 410 works very well for snakes, skunks, and other varmints. I am looking for a multi round 410 (pump, semi-auto) so that I would have more than 1 shot. Also, with the 410 ammo being produced, there are some good home defense rounds.

    Mike, have you considered the Circuit Judge, 18 inch barrel, revolver holding 5 shells (IIRC it will handle the 3″ loads as well as 2.75s) – and can shoot .45 Colt (NOT ACP!) – might suit your needs. Yes it is a Taurus/Rossi but I have seen little to no negative reviews.

    The new Henry lever action .410 is great! It uses Invector chokes and I have fired slugs, buckshot, birdshot, and defensive buck&ball type through mine. over 500 rounds so far and not a single problem! AND re: Gomez comment below, I have a couple Taurus handguns (not in 410 though) and mine are accurate, smooth, and work flawlessly.
