The Lead & Steel LS556PEN-MID-14.5 5.56mm barrel is a lightweight pencil-profile AR-15 barrel designed for shooters who want a nimble front end without sacrificing durability. Turned from 4150 chrome moly vanadium steel and finished in a QPQ black nitride coating, it offers corrosion resistance and long service life while maintaining a clean, understated look. Its 14.50" length with threaded muzzle and M4 feed ramps provides reliable feeding and compatibility with a wide range of muzzle devices.
This barrel is well suited for building a compact, smooth-handling AR-15 for range use, training, or general-purpose defensive applications where balance and reliability matter. The 1:7" twist rate stabilizes modern 5.56x45mm NATO bullet weights, making it versatile for different loads and shooting distances. Lead & Steel’s attention to material selection and machining delivers a barrel that reflects the manufacturer’s focus on practical performance and solid craftsmanship.
