Only 1 left in stock

The 2023 FoldAR® Complete Upper is the pinnacle of compact AR add-on technology, and it just got MoBetta™! Our latest generational improvements include:

-Quick Change Barrel System, allowing the operator to swap calibers and barrels lengths faster and more reliably than any other weapon system on the market.

-Combined with Bootleg Inc.'s Adjustable-Gas BCG, swapping barrels lengths, calibers, and suppression has never been more convenient.

-Modular handguard, allowing armorers three different lengths to choose from, reduced weight, and room to experiment with aftermarket gasblocks.

With FoldAR's patented folding barrel upper, you can configure your standard AR-15 into an extremely versatile weapon system having 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 the Ar-15 platform in ways never before possible! Continuing last year's improvements, the FoldAR comes standard with Bootleg, Inc.'s 4-way Adjustable Gas Bolt Carrier Group, best in-class of all BCG's offered today.

Create and configure your ideal weapon system package with the FoldAR® MoBetta™ Barrel Assembly add-ons. The FoldAR® MoBetta™ Barrel Assembly is interchangeable within seconds, allowing you to configure an "all-applications" weapon system kit within one easily transportable package.
