[SHOT 2016] Nemo Arms

NEMO Arms had some neat products this year at SHOT. NEMO Arms, based out of Montana, is famous for their large bore semi-automatic AR patterned rifles. NEMO Arms first distinguished themselves in the Industry with their semi automatic Omen rifle chambered in 300 Winchester Magnum. At present NEMO Arms is manufacturing rifles chambered in 300 Winchester Magnum, 7mm Remington Magnum, 338 Winchester Magnum, 308 Winchester, 300 AAC Blackout as well as .223/5.56.


NEMO Arms Omen Rifle. For it’s size, this rifle was incredible lightweight. NEMO Arms uses high quality parts and accessories for the their builds.

One trend that was extremely prevalent this year with NEMO Arms was the liberal use of Proof Research Carbon Fiber wrapped barrels. Handling the rifles equipped with the Proof Research Carbon Fiber wrapped barrels, verses the ones that were not, was like night and day in regards to weight.


Proof Research Carbon Fiber barrels were a very common sight at SHOT show this year. It is amazing how lite a rifle becomes when equipped with one of these barrels.

The Firearm Blog writers and I agreed that there was not a lot of innovation in regards to the Ar platform this year. There were only a handful of companies that are pushing the Ar platform forward. Notable exceptions include Cobalt Kinetics and NEMO Arms. It would be fun to shake one of these rifles out.

    Are the Proof barrels nitrided on the inside, or untreated stainless?

    • JumpIf NotZero

      Mostly stainless, although it wouldn’t be impossible to do chrome lined or nitride.

      They’re nice precision barrels, made in house, that are similar to pencil contour, then built back up with the carbon which is tension woven on to the barrel then autoclave cured. It’s the real deal and polar opposite to something like a Christensen that uses an automotive bi-weave pre-made tube tensioned on.

      My Proof AR barrel in my SPR is 3/8th minute all day, I, am not.

    “Pushing the AR platform forward”…

    Just wait until you see how many 300 and 338 ARs there are next year.

    Unfortunately for NEMO, imo, the Proof Barrels are the best thing about them. I just have no interest in the big boy AR platforms.

    • Paul White

      I’d actually really, really like a .338 Federal AR. I just can’t afford one.

      • Thomas Gomez

        That would be fun to own one!

    • TheNotoriousIUD

      Why no interest?

      • Kelly Jackson

        Because JumpIf NotZero is a mall ninja and he only likes things elite commando units use even though his theater of operation is his living room.

        • TheNotoriousIUD

          Dont Tier 1 Scuba Snipers use larger caliber AR’s anyway?

          • Kelly Jackson

            I dunno about all that but I’d love to see some kind of mass produced AR15 long action that could chamber rounds like .300 win mag.

            Bill Alexander once wrote here in the comments the technical reasons behind is choice of not adopting a standard AR bolt design and action in his .338 Lapua Ulfberht.
            He seemed quite convinced that Magnum ARs are not the way to go.
            He surely knows better than me, so I trust hi point of view.

        • JumpIf NotZero

          I’m sorry you seem to dislike me so much, I have no idea who you are.

          • Giolli Joker

            Although I have to admit that I found most of your recent posts more informative than anything else (you threw in a few truly humorous ones as well), you can’t say that you’ve been working hard to be loved by other readers, in the past. 🙂 🙂 🙂

      • JumpIf NotZero

        Because when you’re trying to follow through on a 556 precision AR you can feel the extra work compared to a 308 bolt gun. Now comparing the follow through on a 338 bolt to a 338 semi… Not for me. I’m sure someone can train into that, and also someone could tweak a platform to run like a bolt gun, sacrificing compatibly and ultimately reliability for the effort.

        I’ve already seen excellent shooters go to hell with their first runs at something like an SR25. Just scale everything up with difficulty, but down with development time.

        I also don’t trust the magazines on these new big boy calibers/platforms. The weakest spot on any platform is – and should be – the magazine. I don’t beleive for one second that these niche mfgs are truely putting the time in – not like Magpul would for instance.

      I think the big bore AR platforms are cool, at least in theory. I’ve never actually shot one. As far as “pushing the AR platform forward” though, Cobalt Kinetics is just making it worse by adding idiotic features that nobody would ever reasonably desire, like an automatic mag release. Guns that throw your gear away for you aren’t a step forward…

  • noname

    Me want a proof barrel 🙁

    • JumpIf NotZero

      I have a couple, and they’re excellent, but particularly shine on 24+” length on a bolt gun.

      The break for the gas port and overall size of the AR barrel diminishes the savings. Not sure if they’re pushing their AR barrels right now or not.

    Didn’t the US Army (specifically Special Forces) test and field a small number of these rifles for their snipers?
