The Colt M4 LE6920 Upper Group 16in Stripped brings the proven M4 carbine configuration to your AR-15 build, using Colt’s factory upper receiver and 16" chrome-lined, button-rifled barrel with a 1:7 right-hand twist. This stripped configuration arrives without a bolt carrier group, charging handle, or rear sight, giving builders the flexibility to choose their preferred components while retaining authentic Colt quality where it matters most.

This upper is well suited for general range use, training, and carbine-length builds where reliability and consistency are priorities. The fixed front sight base and carbine handguards provide a familiar, durable interface that works equally well with iron sights or optics mounted on the flat-top receiver. Whether you are refreshing an existing rifle or starting a new project, this Colt upper offers a solid foundation backed by the company’s long-standing reputation for dependable AR-15 components.
