One Rifle to Rule Them All: an exceptionally versatile 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 FoldAR® is the pinnacle of Concealed Carry Rifle platform technology. 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 System add-ons. The FoldAR Barrel System is interchangeable within seconds, allowing you to configure a multi-role 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, under 15″ overall length.
- 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, under 15″ overall length.
- 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, under 15″ overall length. 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 under 18″ overall length. When a full-length fixed rifle stock is attached it folds in half, right under 18″ overall length.
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 – Selected for its wide performance spectrum, especially suppressed energy delivery.
- 7.62×39 – Selected for higher ballistic energy and broad ammunition availability.
- .350 Legend – Straight-walled cartridge for hunting, with less recoil and more penetration. (Call 903-308-0016 for inquiries and lead-time)
- .22ARC – Selected for its flat trajectory, low recoil and high velocity. (Call 903-308-0016 for inquiries and lead-time)
- 6mm ARC – Exclusively within our Proof Research Carbon Fiber line of barrels, 6ARC is selected for its high performance at distance. (Call 903-308-0016 for inquiries and lead-time)
