Why hasn't anyone made an AR-18 for 7.6251 NATO?

Brownell said in their interview in forgotten weapons that they would also make a BRN-180 upper for AR-10 lowers. So far there hasn't been any information about it.

What's going on? Is the problem with the AR-18's design that makes it unsuitable for a battle rifle / DMR ?

Im assuming having the internal carrier of the gun being "suspended" by the guide rods and springs inside of it and not touching the walls could mean that it would cause problems with a higher powered round like the 7.62 NATO hell having 2 small springs could easily be a point of failure compared to a big spring.
That's why only the short stroke gas piston was copied from the AR-18 and not the weird 2 spring guide rod system.

    Wouldn't be worth the cost of production because not enough people would buy it. AR10 & its aftermarket is ubiquitous

      Same argument could be said about the AR-15 and it's after markets.

      A modern day AR-16 would be cool, but the market for such a thing is probably so small that the development and production cost wouldn't be worth it.

      What if a country or sth decided to copy the design of the Ar-18 to make a battle rifle / DMR similar to how the Roaches made a copy of the HK 417/ Kraut AR-10.
      Do you think it would turn out as a good battle rifle? I personally think it would suck ass especially with the loose block and the 2 springs and guide rods but it's worth it as an experiment at least for somebody to make one.

      Someone hadn't already done the homework that they could just steal so it's not gonna happen dude.

      The design for the AR-16 already exists it's literally the same just scalled up unless there is something fundamentally wrong with the design that makes it crap for a battle rifle.

      SCAR 17/H, CZ Bren 2 DMR, and the B&T APC308 exist which are CLOSE ENOUGH examples already

      Yes there are guns that use short stroke that are DMR/ battle rifles but im talking about the actual AR-18 not just one part that has been copied. The loose block, the guide rods and springs etc.

          Canadian guns suck ass tho

          Because the G3 is superior than anything you can come up with.
          Also HK417 you idiot

          The Ar-10 was superior to the G3 and Fn fal in preety much everything. The buffer tube mitigates the recoil while making the weapon lighter. This is why the G3 has been replaced with AR-10s in DMR/battle rifle use.
          The HK417 is just a piston AR-10 but German. Nothing simmilar to the AR-18. It has a buffer tube.
          The Roaches replaced their G3 with a domestically produced bootleg HK 417.
          That's how Superior the AR-10 was and is to the other battle rifles.

      That would be the most sold BRN of all time.

      Its what most people are WAITING for. The 308 BRN. Just like how people want the 308 jakl

    Seriously look at this pic related.
    Those things look fragile as frick, the design is not scalable to 7.62 NATO. That's why brownell probably abandoned it.
    Compared to the AR-10 and later AR-15 design, yes you can't flip the stock, yes it is more complex to manufacture but that buffer tube is great for recoil dampening making the AR-10 at the time lighter yet at the same time more accurate and controlable in automatic fire compared to the FN FAL and especially that piece of shit, the M14.

      I owned a Texas built M1A. Sold it to by an N6(before Noveske died). Couldn’t be happier.

    Im guessing you mean, specifically for AR lowers. No problem with the design, it just hasn't been done. The SCAR 17s and BREN BR are 7.62 AR18 actions, but with modern accoutrements like extruded receivers and polymer lowers; so it is certainly possible. Just that nobody has done it with backwards compatibility yet.

      Im not an engineer but coming from a layman's perspective the 2 spring guide rods seem like a point of failure when dealing with a higher powered round. Probably why other short stroke gas piston rifles don't have something simmilar.

      Tho i think the AR-18 is kinda over praised, i still think it's sad that it didn't get any chance to shine and it's mechanism was just copied. It is cool i always loved but im more of a battle rifle kinda guy

      That's why i think since there's an updated assault rifle/ AR-15 lower variant there should be a battle rifle / AR-10 lower version. So that every niche has one. Ofcourse it is not profitable so probably won't happen.

        I think the AR-18 and its variants (like the K2) are the final form of the mass-produced, mass-deployed fighting rifle tbh. It’s cheaper and more compact than the AR-15 and the piston makes it prescient for the mass suppression that has become the norm. As to your Battle Rifle version, the Sig Spear is basically a scaled up AR-18.

        Why do they only have 1 handguard option still? I do not want mlok.

        2 spring rods would be more stable not less. You are applying logic in the same way people assume EV cars are more reliable than combustion because there are less moving parts, problems are completely different and the longevity falls with materials and construction moreso than design in most cases.

    the world does not need more tacticool military bullshit
    there are enough weapons of mass murder in existence already, the real challenge now is in reducing ammunition costs, getting more suppressors on guns, getting more modularity like swappable barrels etc
    imagine you had a bullpup bolt action integrally suppressed gun in 44 magnum for hunting deer that you could quick-swap a 22lr barrel into for squirrels. we will never have a gun like this though because people just have an endless greed for tactislop

      >integrally suppressed
      Why would I want this when commercial subsonics exist in vast quantity and variety or I could just roll my own at home from bullets I bought online by the thousand?

      The only way ammo costs are going down is if the US gets into a shooting war and it actually manages to spin up a dozen new ammo plants. And that the war ends with the US intact and the new plants are allowed to continue manufacturing ammo and can sell it to civilians. Legislation and economics makes starting up any new chemical plant expensive, and explosives basically triple those issues. There's a reason domestic black powder production only resumed when the Pentagon actually invested money into our last bp plant. No private investor or industrial company wants to fit the bill in starting up a new plant.

      Quick barrel changes are a meme especially for your idea. You are most certainly going to use an optic for hunting and the poi shift from 44 to 22 would mean you would have to re zero or even swap out your optic. might as well go with a swappable upper like system instead.

        High end Euro hunting rifles with swappable barrels mount the optic on the barrel for this reason

      Why on earth would I want one gun when I could just have two. Any .44 platform would be horribly overbuilt for .22 and vice versa

    It makes me irrationally angry that they have the perfect platform for a folding/stockless radial-delayed AR9 and they instead chose to whitelabel a direct blowback 9mm upper.
