The Lead & Steel LS556GOV-CAR-11.5 Match Grade 5.56 NATO 11.50" Thread Barrel is built for shooters who demand precision from a compact AR-15 platform. Machined from 4150 chrome moly vanadium steel and finished in QPQ black nitride, this government-profile barrel combines strength, corrosion resistance, and long service life. Its 11.5-inch length with threaded muzzle makes it ready for your preferred flash hider, brake, or suppressor, while the dimpled gas block area helps ensure consistent alignment.

Designed around a carbine-length gas system, this barrel features M4 feed ramps, a 1:7 twist rate optimized for modern 5.56x45mm NATO loads, and a sub-MOA guarantee when paired with MK262 ammunition. The result is a compact barrel that balances reliability and accuracy for range work, training, and general-purpose carbine builds. Lead & Steel’s attention to detail and commitment to quality manufacturing are evident in every contour and marking on this match-grade barrel.
