Build & ergonomics

The externals focus on low weight and durability. The barrel assembly, free-float front, receiver parts, Light Ops stock, and pistol grip are made from nylon-fiber reinforced polymer. Key metal parts (including the barrel components, flash hider, enlarged charging handle and controls) use aluminum and zinc alloys, while high-stress small parts (bolts, pins, ejection port parts) are steel. The overall fit is tight, with minimal wobble between the upper and lower receiver.
