Description
Imagine you’re piecing together a practical, no-nonsense rifle setup for anything from home defense to a long day at the range. You want something tough, adaptable, and ready to go without a pile of extra parts. You keep circling back to the AR platform, but maybe you’re curious about something built from the ground up with a different philosophy. That’s where the Beretta ARX100, .223/5.56, 16″, 30rd, Folding Stock, Flat Dark Earth enters the picture. It’s a factory-built, battle-proven rifle that offers a compelling blend of Italian engineering and practical features at a clear price point.
So, what is it? The Beretta ARX100 is a modern semi-automatic rifle chambered in .223 Remington/5.56 NATO. It features a 16-inch cold hammer-forged barrel, a 30-round magazine, a fully ambidextrous folding stock, and comes in a Flat Dark Earth finish. It’s a complete, ready-to-run system designed for reliability and ease of use, requiring no gunsmithing required to get started. Priced at $1375.59, it sits in a competitive spot, offering features often found on more expensive custom builds.
Let’s break down the key features. First, the ambidexterity isn’t an afterthought—it’s core to the design. The non-reciprocating charging handles, magazine release, bolt catch, and fire selector are mirrored on both sides. You can even swap the ejection port to the opposite side in seconds without tools. This makes it a fantastic choice for left-handed shooters or for anyone who values adaptable handling. The polymer-reinforced construction keeps the weight down to a handy 6.8 lbs unloaded, which is a real benefit for all-day carry.
The folding stock is a huge practical advantage. It locks solidly in both extended and folded positions, reducing the overall length to just over 26 inches for storage or transport. When you combine that with the rifle’s innate reliability—a trait honed from its military ARX160 sibling—you get a package that’s both compact and trustworthy. Here’s the thing—while it uses proprietary magazines, it’s designed to be compatible with standard AR-15 magazines from brands like Magpul and Lancer, giving you plenty of affordable, proven options. The cold hammer-forged barrel ensures longevity and consistent accuracy, a premium touch at this price.

Pros & Cons
The pros are clear: outstanding ambidextrous controls, a true folding stock for compactness, proven reliability from a military lineage, and a lightweight, durable polymer build. It’s a complete rifle right out of the box. The cons? The trigger has a spongier, longer pull than a tuned AR-15 trigger, which is a common trade-off in this price bracket. Some find the polymer feel less substantial than aluminum, though it’s incredibly tough. Aftermarket support is more limited than for the ubiquitous AR-15, but core components and mag compatibility cover the essentials.
Who is this rifle for? It’s ideal for the shooter who values a ready-made, highly adaptable tool over a custom project. Left-handed shooters get a truly ambidextrous platform without modifications. Those with limited storage space will appreciate the folding stock. It’s also a smart pick for someone wanting a rugged, modern rifle with a distinct identity from the sea of AR-15s, without sacrificing the practical benefits of the 5.56 platform. This model is available at firearms-missouri.com for Missouri residents and nationwide to compliant states.
Frequently Asked Questions
Q: Does it take AR-15 magazines and accessories?
A: Yes, it accepts most standard AR-15 pattern magazines (Magpul PMAGs, etc.). The upper rail is MIL-STD-1913 Picatinny for optics and lights, but the handguard uses a proprietary attachment system, so not all AR-15 handguard accessories will directly mount.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the 16-inch barrel comes with a standard 1/2×28 thread pitch, allowing you to install common flash hiders, compensators, or muzzle brakes. A standard A2-style flash hider is installed from the factory.
Q: How does the price compare to building a similar AR-15?
A: For around $1375, you’re getting a factory-built rifle with a folding stock and full ambidexterity. To build an AR-15 with a quality folding stock adapter and ambi controls, you’d likely meet or exceed this price—and you’d still be assembling it. The ARX100 represents a solid value as a complete, feature-ready package.
If a rugged, ambidextrous, and compact-ready rifle from a legendary maker fits your needs, the Beretta ARX100 presents a compelling case. See the full details on our product page.
