FightLite Industries Unveils DFX Belt-Fed Upper Receiver for AR Platforms

FightLite Industries has announced the upcoming release of its DFX Dual-Feed Upper Receiver, a belt-fed modular system designed to seamlessly upgrade standard AR-15, M16, M4, or HK416 pattern lower receivers. The new DFX aims to combine sustained-fire capability with the flexibility of traditional magazine-fed operation, targeting civilian enthusiasts and professional users seeking enhanced performance.

Dual-Feed Versatility and Drop-In Installation

The DFX upper receiver distinguishes itself with its patented Dual-Feed design, allowing operators to utilize both USGI M27 linked ammunition and standard AR magazines. This adaptability provides users with expanded options in various scenarios without requiring modifications to the host lower receiver.

Installation is intended to be straightforward, taking only minutes and requiring no permanent changes to the lower. The kit comes complete with a detailed operator’s manual, robust recoil spring, a dedicated bolt catch, and 100 M27 links, equipping users for immediate use out of the box.

Features Engineered for Performance

At the core of the DFX is a free-floating, heavy-profile barrel designed for sustained fire and improved heat management. The piston-driven operating system, a patent-pending short-stroke gas-piston unit, enables cleaner operation and reduced maintenance, even under strenuous conditions. The system is also equipped with a MIL-STD 1913 quad-rail handguard and offers optional M-LOK configurations, supporting a wide array of modern optics and accessories.

Additional highlights include: - Compatibility with MIL-Spec AR-15/M16/M4 and HK416 lower receivers - 5.56x45mm NATO / .223 REM chambering - 16.25-inch barrel with 1:7” twist and ½”-28 threading - Precision-machined 7075-T6 billet upper, feed cover, and components - Manganese phosphate and hardcoat anodized finish for durability - Enhanced, full-auto bolt carrier group for reliability in high-volume use

Market Position and Anticipated Launch

Priced at $3,995, the DFX upper is slated for release in Fall 2025. FightLite emphasizes robust support with in-stock spare parts, accessories, and a dedicated customer service team. The company states the DFX has been conceptualized for responsible gun owners, law enforcement, and security professionals who require a reliable and flexible high-volume firing solution.

Pre-orders are now open, with orders to be fulfilled sequentially as availability comes online. As interest grows around modular belt-fed systems, the DFX positions itself as a significant entry into the evolving AR accessory market, enabling users to experience sustained-fire capability without departing from familiar semi-automatic platforms.

U.S.-Made Innovation for Modern Demands

Designed, engineered, and manufactured in the United States, the FightLite DFX leverages domestic expertise in accurate, durable weapon systems. The development team—comprising professional shooters, machinists, and designers—has focused on providing superior sustained-fire performance while accommodating the practical needs of today’s armed citizens and professionals.
