What does AI have to say about a modern AR180?

I asked Grok 2 AI a simple question,

What would a modern AR180 rifle look like?

Here is what it had to say.

A modern AR180 rifle, while staying true to its original design ethos, would likely incorporate several contemporary features and materials to meet current standards of functionality, reliability, and user preference. Here’s what you might expect:

– **Material Use**: The original AR-18/AR-180 utilized stamped steel for cost-effective mass production. A modern variant might retain this for economic reasons, but could also feature more durable materials or combinations like aluminum alloy for the receiver, possibly even polymer for some parts to reduce weight, similar to what Armalite did with the AR-180B.

– **Design and Ergonomics**:
  – **Upper Receiver**: The upper could still use the distinctive AR-18 profile but with added Picatinny rails for modularity, allowing users to attach various optics and accessories easily. There might be options for side charging handles or even ambidextrous charging, enhancing user flexibility.
  – **Lower Receiver**: While traditionally stamped steel, modern designs might opt for a more durable or lighter material. The controls would likely remain similar to AR-15 patterns for familiarity, including an ambidextrous safety/selector switch.

– **Operating System**: The AR-18’s short-stroke piston system, which was ahead of its time, would be retained for its reliability and cleanliness compared to direct impingement systems. This system would be refined for better performance, possibly with adjustable gas settings for suppressed use or different ammunition types.

– **Barrel**: Modern AR180s would likely feature cold hammer-forged or button-rifled barrels for longevity and accuracy, with options for different lengths and twist rates catering to a variety of uses from close-quarters to long-range engagements.

– **Stock and Accessories**:
  – **Stock**: While the original had a side-folding stock, modern versions might offer various stock options, including fixed, folding, or adjustable stocks compatible with AR-15 stocks for aftermarket support.
  – **Grips and Forearms**: The grip and forearm might be updated to ergonomic polymer versions or include M-LOK or KeyMod slots for attaching lights, laser sights, or other tactical accessories.

– **Magazine Compatibility**: Given the original AR-180’s use of proprietary magazines, a modern design would probably adapt to use the widely available STANAG magazines, enhancing its appeal by allowing for greater aftermarket support and magazine availability.

– **Sights**: Modern iterations would likely include options for both traditional iron sights reminiscent of the original design and rail systems for mounting advanced optics or holographic sights.

– **Suppressor Compatibility**: With the trend towards quieter firearms, the design might include a barrel threaded for suppressors or built-in features that improve performance with suppressors, like an adjustable gas block.

– **Trigger**: There might be an emphasis on a crisp, clean trigger pull, possibly with aftermarket options for trigger upgrades, similar to those available for AR-15s.

– **Color and Finish**: While black was standard, modern AR180s could come in various Cerakote finishes for durability and personalization.

– **Legal and Market Considerations**: In regions like Canada, where the AR-180 has seen a resurgence due to its non-restricted status, modern variants would be designed with legal considerations in mind, ensuring they meet local firearm regulations while maximizing functionality.

In essence, a modern AR180 would blend the simplicity, reliability, and unique design elements of the original with the modularity, customization, and performance enhancements that contemporary shooters demand.

It used 15 sources from the internet to come to these conclusions, including a few articles from this site.

I followed up by having it make me a picture of said rifle.

I would call that part a fail.

Surplus AR180B Parts at AR180Parts.com

Just a quick heads up that I’ve got some surplus 180B parts in stock and ready to go.

Biggest and hardest to find parts are complete bolt carrier groups. I’ve been able to put together a few of these and I don’t know if I’ll ever be able to source all these parts again. By the way these can be machined to work in an original AR180 if needed. I don’t provide the service but any competent machinist or gunsmith can help you out.

Another item that has been asked about a lot are original extended length hammer and trigger pins. These are new old stock Armalite production, as are all these parts.

Take a look around and see if there is anything you might need to finish a build or to have spares.

I’m Reposting Content to Twitter/X.com

I just wanted to give everyone a heads up that I am reposting my original blog posts over to Twitter/X.com.

I’ve been having some issues with other social media platforms shadow banning me so I’m doing this to hopefully build my audience over there.

First post is live.

Jump over there for a trip down memory lane or see my older content for the first time.

Please follow, like and share my stuff over there. I can’t do this without your support.

Thanks again.

This is How We Roll — Pin

I’ve received some emails lately about roll pin availability for the original AR-180’s. I decided to take a deep dive into the subject and I am happy to report that we should be able to source our roll pins by using or modifying AR15 roll pins.

Lets start with the largest roll pin on the AR180, the magazine catch pivot. It is .094″ in diameter and .562″ long. You should be able to make use of an AR15 trigger guard roll pin. It is .093x.625. Most of them are super tight in a trigger guard so I don’t see any reason they wouldn’t work. They would just need to be cut down.

Next we have the ejector retaining pin. It is exactly the same as what is used in an AR15 bolt. They both measure .062x.437. By the way, all the ejector and extractor parts from an AR15 bolt can be used in your AR180 bolt.

Two of the same pins are used in the bolt catch and the bulkhead plungers for the butt stock. They measure .062x.312. The closest thing from an AR15 is an A2 windage knob roll pin. It measures .062x.375. Take a little off the top and you will be good to go.

Finally the guide rod retaining plunger and the dust cover use a .062x.250 roll pin. The exact roll pin is used in A1 rear sight drums.

These roll pins can also be ordered in the exact size needed but often you are buying them in bulk to get one or two. Repurposing AR15 roll pins might be a better way to go for some folks.

I’ve considered doing just that. Ordering all the sizes needed for the AR180 and selling them as a kit. Let me know in the comments below, would you buy one?

Costa Mesa News!

As of January 1, 2023 all Costa Mesa AR180’s are C&R eligible!

AR180 production in Costa Mesa CA took place from 1969 to 1972 but since production records no longer exist it was impossible to exactly date a particular gun by serial number. That is no longer the case as all of the 4018 rifles produced fall under the Curio & Relic classification.

How do we know? Lets go directly to the source, https://www.atf.gov/firearms/curios-relics

A regulation implementing federal firearms laws, 27 CFR ยง 478.11, defines curio or relic (C&R) firearms as those which are of special interest to collectors by reason of some quality other than is associated with firearms intended for sporting use or as offensive or defensive weapons.

To be recognized as C&R items, firearms must fall within one of the following categories:

  1. Firearms which were manufactured at least 50 years prior to the current date, but not including replicas of such firearms;
  2. Firearms which are certified by the curator of a municipal, state, or federal museum which exhibits firearms to be curios or relics of museum interest; and
  3. Any other firearms which derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or because of their association with some historical figure, period, or event.

Personally I think all of the original production AR180’s (Howa & Sterling) should be considered C&R, but I don’t make the rules. For those that don’t know all AR18’s are considered C&R. There is a separate list that you can download at the link above that lists them. The AR18’s were not yet 50 years old when they made it on the list. I’m not sure why they left out the 180’s.

My late Costa Mesa AR180 in it’s original box

Why does this matter? If you get yourself a C&R FFL license for $30 you can have a C&R weapon shipped right to your door.

My postal carrier delivered my AR18 right to my hot little hands. It was an awesome experience. Now we can trade our 180’s the same way!
