FoldAR MoBetta Barrel System

One Rifle: an extraordinary rifle designed to accomplish multiple configurations of calibers and barrel lengths without compromising any areas of performance, reliability, safety or accuracy. History of the “One Rifle” begins in 1920 and ends with FoldAR leaping far beyond the “One Rifle” concept in 2023.

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.

Create and configure your ideal Concealed Carry Rifle^TM with an additional FoldAR^® MoBetta^® Barrel System. Our patented folding upper gives you the highest level of concealability possible without sacrificing any areas of performance, reliability, weight, or safety when attached to your FoldAR MoBetta firearm or Complete Upper. The FoldAR MoBetta Barrel System is interchangeable within seconds, allowing you to configure an “all-applications” weapon system kit within one easily transportable package.

Important Notes:

1. Only for owners of a 2023 FoldAR MoBetta firearm or complete upper.
2. Not interchangeable with third part upper receivers or 2018-2022 FoldAR products.
3. Swapping between 6.5 Grendel and .300 AAC Blackout or 5.56×45 NATO requires a bolt/BCG swap.
4. Swapping between .300 AAC Blackout and 5.56×45 NATO does not require a bolt/BCG swap.

Barrel Selection Guidelines:

• 9.0″ – Our most popular among operators because of its ability to remain suppressed while maintaining concealability within a small 16″ EDC sling-pack. Combined with a collapsed stock or pistol brace and a compact suppressor (6″), our 9.0″ barrel allows the weapon system to fold in half, at 14.75″.
• 10.5″ – Custom Order Request. We have not pursued this intermediate short barrel length because it offers no ballistic or concealment advantages over the 12.5″ barrel, as both will still fold down to 14.75″. However, for some operators and requirements there may be a slight ballistic and concealment benefit in a 10.5″ that rests between our 9.0″ and 12.5″ configurations.
• 12.5″ – Our second most popular among operators because of its mid-range capability while maintaining concealability within a small 16″ EDC sling-pack. Combined with a collapsed stock or pistol brace, our 12.5″ barrel allows the weapon system to fold in half, at 14.75″. It should be noted, this setup can still squeeze into most 18″ EDC packs when a compact suppressor is installed (6″). If having a suppressor that remains attached is not your priority, then our 16.0″ barrels will deliver the highest ballistic performance per container volume.
• 14.5″ – Custom Order Request. We have not pursued this intermediate barrel length because the concealment benefit over our 16.0″ is not significant. However, for some operators and requirements there may be a slight ballistic and concealment benefit in a 14.5″ that rests between our 12.5″ and 16.0″ configurations.
• 16.0″ – Our most popular among civilians, marksmen and hunters because of its Always-Non-NFA legal status and its capabilities of performing at distance with precision. Combined with a collapsed stock, our 16.0″ barrel allows the weapon system to fold slightly over half, at 17.75″. If a full-length fixed rifle stock was attached, it would fold in half, also at 17.75″.

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.
• .300 AAC Blackout – Choose 300BLK for its wide spectrum of performance in delivered energy and suppression.
• 6.5 Grendel – Choose 6.5 Grendel for its stability and higher energy delivery and at distance.
