Harrington & Richardson 723 Style 5.56 Carbine 16"

A Piece of Rifle History

Harrington & Richardson's 723 Style Carbine captures the essence of late-1980s military rifle design—that pivotal moment when the M16A1 was giving way to the M4 carbine concept. This is not a modern interpretation; it's a genuine throwback to a specific era of American firearms engineering.

What You're Getting

The rifle features an H&R-marked M16A2 lower receiver paired with an M16A1 upper receiver, creating an authentic transitional-period configuration. This isn't nostalgia for its own sake—it's a functional, reliable platform that serves equally well as a foundation for your clone-build projects or as a ready-to-run rifle.
