The FightLite DFX UPR 556 PIC 16.25" BLK is a drop-on upper receiver group engineered to bring dual-feed versatility to any MIL-Spec AR15, M16, or M4 lower. Built around a heavy-duty, free-floating fixed barrel and a slim Picatinny rail handguard, this upper is designed for reliable belt-fed operation while still accepting standard AR magazines. Its gas-piston and pusher-rod system delivers smooth cycling and reduced fouling, all in a compact, purpose-built package.

This DFX upper receiver group is chambered for .223 Remington/5.56 NATO and features a 16.25" barrel optimized for general-purpose shooting, training, and extended range sessions. The patented dual-feed design lets shooters transition between M27 linked ammunition, STANAG pattern magazines, and compatible SAW drums without permanent modification to the lower receiver. With its robust construction and thoughtful engineering, the DFX showcases FightLite’s focus on innovation and practical performance.
