ATI Omni AR 15 Polymer Lower

ati polymer lower

Just announced, presumably at the recently completed SHOT Show. I wonder about availability. ATI’s website is here.

Two types are available and they are a stripped lower and a complete lower that only needs to be attached to an upper of the shooters choice. When referring to a multi-caliber lower in the case of the “Omni” that would include .22 LR, .223/5.56 and .410 uppers.

When recently introduced the price of the stripped lower was $43.95 with the complete lower for $134.95. The complete unit includes a GI type six position adjustable stock, buffer tube, buffer with spring, the polymer lower itself, trigger group as well as the fire selector, bolt release, magazine release and both takedown pins.”

    OH MY GAWD! An all plastic gun that defeats metal detectors and will be used by right wing extremists (terrorists) to commit mass murder in the streets and the skies! /sarc

    I’d be interested to see how well that lower holds up with centerfire loads.

      Bushmaster has something similar with their “Carbon 15”, it’s some type of carbon composite receiver.

      I like the idea, but I also wonder how well it will hold up. I guess people thought the same thing about Glocks when they came out, but that’s worked out very well.

        Great point with the Glock.

      • Jim22 says:

        The Glock analogy is and isn’t apt. It is because Glock came up with a very tough polymer when they made their pistols. But they molded steel slide rails into the polymer frame.

        This polymer lower doesn’t even contact the reciprocating bolt. It’s inside the upper receiver. I would think that would make the engineering easier to accomplish. The stress points on this thing are the holes for the pins – especially the hammer pin, and the buttstock attachment.

        The concern about using the buttstock as a club, below, is a valid concern, I think.

    Some random thoughts. We The Elite People of Culture of Corruption in Washington Dc really must have fear as their guiding principles nowadays. They’re in the “circling the wagons” phase! Need proof? Feema is quietly moving large, heavy duty military equipment around the country. Silence on their Internment camps. Weapons purchases continue unabated. On HBOGOHD channel 2/7/2013 a documentary on “Taking of Maryah”…with air support, fire power, snipers and ground support. Where’s “posse comitatus?” Search warrants? Wanton shooting of american civilians, by law enforcement, is now justified? “Rule of Law” is non-existent? What’s up with this tyranny?
    Now comes this story:
    Liberty National News (Tea Party Wire) 2/8/2013
    The outrageous and unexplainable purchase of now 1.6 BILLION bullets by the Feds can be summed up in the following sentence.
    the DHS has purchased enough bullets over the last 10 months to wage a full scale war for almost 30 years.
    That from the news that feds have ordered yet another round of ammo, this time 21.6 million rounds of hollow point .40 and .9 ammo. The FedBid document has the order details. The document reads to suggest the ammo is heading to a training facility in New Mexico. Perhaps this is indeed the final destination for the ammo. But why would the feds train with more expensive hollow point ammo? And 21.6 million rounds?
    Last weekend I fired about 250 rounds of .40 at a range here in Virginia. This over a period of two hours. If my math is correct (and it may not be thanks to public education), it would take me eight hours a day, firing 1,000 rounds a day, for approximately 59 years, to fire that much ammo. And that’s just a single order for the fed.
    Where are our representatives on this? What is going on with all of this ammo hoarding?
    Hollow points have been banned across these fruited plains!!! What gives??? And 1.6 billion bullets, most are hollow points…Napolitano is really afraid, shakin’ in her boots or Obama is seriously preparing for some really serious “Executive Orderin'” times.Pray. Amen.

      It may be interesting to see how much of this comes up missing, then turns up somewhere like Syria or with the Mexican drug lords.

    Vulcan makes, or made, polymer AR lowers.
    I’ve read good & bad things about them.
    I suppose for a have fun at the range, they might be OK.
    Wouldn’t want to use the buttstock as a club, ya know?

    • notamobster says:

      I would use it, Greg. There are some very tough polymers out there. Anyone ever own a Pelican Case? Very tough stuff. Getting into carbon composites? Also a very tough, lightweight alternative.

    I know a guy…;-) that has been running his 6.8SPC upper on a New Frontier Armory polymer lower with no issues. go to New Frontier Armory and watch their torture test videos.

    Got a Vulcan V15 poly lower w/ DPMS lpk, buffer tube assembly and BCM upper; no probs WHATSOEVER; it’s all personal preference.
