Ballistic Advantage AR-15 barrels come in a great variety of chamberings, lengths, and contours, so you are certain to find the exact barrel you need for any type of rifle you are building or upgrading.

The Government, M4, and SPR, and DMR profiles are all well-known among AR-15 aficionados. All barrels are chambered in 5.56 NATO, so they accept both military-type 5.56x45mm and civilian .223 Remington ammo.
