One Rifle to Rule Them All: an exceedingly extraordinary rifle, having all the advantages of the “One Rifle”, but also including the ability to conceal inside an EDC backpack, remain fully assembled, and be deployed within seconds.
The 2025 FoldAR® is the pinnacle of Concealed Carry RifleTM conversion technology, and it keeps getting MoBetta®! The FoldAR upper receiver holds the core of our folding barrel interface technology, making the AR-15 the most modular it has ever been. Our latest generational improvements include a quick-change barrel system, allowing tool-less caliber/barrel swaps faster and more reliably than any other takedown weapon system.
With our patented folding upper, the FoldAR platform gives you the highest level of concealability possible without sacrificing any areas of performance, reliability, weight, or safety. Deployment and stowage only takes a matter of seconds and is an extremely simple and reliable process, allowing you to quickly and efficiently carry and transport your firearm in ways never before possible.
Create and configure your ideal weapon system package with the FoldAR Barrel Assembly add-ons. The FoldAR Barrel Assembly is interchangeable within seconds, allowing you to configure an “all-applications” weapon system kit within one easily transportable package.

One Rifle – Barrel Selection Guidelines:
- 9.0″ – Our most popular barrel length for CQB-work because of its ability to remain suppressed while maintaining concealability (Colion Noir) within a small 16″ EDC sling-pack. Combined with a collapsed stock or pistol brace and a compact suppressor, our 9.0″ barrel allows the weapon system to fold in half at 14.75″.
- 10.5″ – As the newest addition to our barrel lengths, the 10.5″ barrel matches nicely with a standard carbine stock or pistol brace and compact suppressor, also allowing the weapon system to fold in half at 14.75″.
- 12.5″ – Because of its mid-range capability while maintaining concealability within a small 16″ EDC sling-pack, or suppressed within a standard 18″ backpack, our 12.5″ barrel configuration dominates in performance and concealability. Combined with a collapsed stock or pistol brace, our 12.5″ barrel allows the weapon system to fold in half, at 14.75″. Note: this setup fits in most 18″ EDC packs when a compact suppressor is installed.
- 16.0″ – (Rifles) Our most popular among civilians, marksmen and hunters because of its Always-Non-NFA legal status, its capabilities of performing at distance with precision (Alabama Arsenal), and its ability to continuously return to zero (Pew Pew Tactical). Combined with a collapsed stock, our 16.0″ barrel allows the weapon system to fold slightly over half, at 17.75″. When a full-length fixed rifle stock is attached, it folds in half at 17.75″.
One Rifle – Caliber Selection Guidelines:
- 5.56×45 NATO – We chamber and identify our barrel as .223 Wylde, as the best chamber design to safely and precisely accept a variety of both .223 Remington and 5.56×45 NATO ammunition. Choose this caliber for the widest availability of affordable ammunition for training to precision hunting, as well as various Law Enforcement and Defense applications.
- .300 AAC Blackout – for its wide spectrum of performance especially in delivering suppressed energy.
- 7.62×39 – for its higher ballistic energy and its general availability.
- .350 Legend – a straight-walled cartridge for hunting, with less recoil and more penetration.
- .22ARC – for its flat trajectory, low recoil and high velocity.
