Product Description The White Label Armory WLA-BRL-4001 is a 7.5-inch AR15 barrel chambered in 5.56 NATO, purpose-built for pistol-length AR15 builds. Machined from 4150 Chrome Moly Vanadium (CMV) steel and marked directly on the barrel, this Government Profile barrel features a 1:7" twist rate that reliably stabilizes a wide range of 5.56 NATO and .223 Remington projectiles. The pistol-length gas system configuration makes it an excellent choice for compact, maneuverable SBR or AR pistol builds. The threaded muzzle end accepts standard 1/2x28 muzzle devices, and the Government Profile contour balances weight savings with heat dissipation for extended range use.
