Ar-15/M16 Carbine Barrel
Buy It Now: $229.99
Carbine-length barrel machined from high-grade 4140 carbon steel replicates the exact dimensions of a mil-spec M4 barrel forward of the gas port.
The portion under the handguard is .140" thicker than a standard M4 barrel to provide extra rigidity to resist loss of accuracy caused by barrel overheating. Chambered for 5.56mm NATO, with 1-9" rifling. Comes with gas port pre-drilled, barrel extension with M4-style feed ramps, and "-28 tpi muzzle threads to accept a wide range of aftermarket flash hiders and muzzle brakes.
A hard, black oxide finish adds surface strength and corrosion resistance, and matches the factory hardcoat anodizing on most receivers. More . . .
