FN produces barrels for the U.S. military's M4 and M16 contracts, and this is that manufacturing capability sold as a component. A 16-inch 5.56 NATO barrel with a carbine-length gas system, button rifled and chrome lined the way service barrels are built for corrosion resistance and long round counts.

Carbine gas remains the most forgiving system for a 16-inch build, running reliably across a wide ammunition range. If you want an AR-15 barrel from a company that actually builds them for the government, this is the shortest path to one.
