The Colt M4 Carbine is a 5.56 NATO rifle with a 16-inch chrome lined barrel and a C-marked barrel. The description also notes the upper and bolt carrier group, along with an adjustable stock and a black finish. The record shows the carbine as used, while the supplier describes it as new and uses a stock photo.

A 16-inch carbine with an adjustable stock suits a shooter who wants a familiar layout for range practice, general use and a first build on a known platform. The chrome lined barrel is listed as a key detail of this configuration. Because the condition is listed two ways, confirm it with the seller before the carbine reaches your dealer. The adjustable stock is a practical feature for a shooter who wants to set the fit.
