Brownells has a great price on the Brownells Ar-15/16 M4 Carbine Barrel, at only $275.95.

Stripped, M4-contour barrel machined from ordnance-grade 4140 chrome-moly steel is ready for your next custom carbine build or re-barrel job. Comes with the ramped, M4-type barrel extension installed and gas port pre-drilled. You supply the gas block, front sight, muzzle brake/flash hider, and handguard of your choice, so you don’t pay for extra parts you won’t use. Muzzle is pre-threaded with “-28 tpi threads to accept a wide array of aftermarket flash suppressors, compensators, and muzzle brakes. Chambered for 5.56mm NATO, with a choice of 1-7″ twist rifling for best performance with military ammo, or 1-8″ twist for compatibility with a wider range of bullet weights. Stress relieved to prevent accuracy-robbing distortion when barrel heats up, with a corrosion- and wear-resistant dark gray/black Parkerized finish that matches many factory receiver finishes. SPECS: 4140 chrome-moly carbon steel, Parkerized, dark gray, matte finish. .750” O.D. at gas port position, .700” O.D. at the muzzle shoulder. Chambered for 5.56mm NATO. Not chrome lined. Length measured from rear of barrel extension to muzzle. 1-7″ Rifling – 16 ” (41.9cm) long, .670” O.D. under handguard. 1 lb. 12 oz. (794g) weight. 1-8″ Rifling – 17″ (43.2cm) long, .650” O.D. under handguard. 1 lb. 14 oz. (859g) weight.
