Harrington & Richardson 723 Retro 5.56 NATO 14.7" Pinned Barrel - 30 Rd

Channel the legacy of late-1980s military carbines with the Harrington & Richardson 723 5.56 NATO Carbine—a lightweight, no-frills rifle that captures the spirit of a pivotal era in firearm evolution. Built to mirror the transitional phase between the M16A1 and the emergence of the M4, this rifle delivers authentic styling with dependable modern performance.

At its core, the H&R 723 embraces the “K.I.S.S.” philosophy—keeping things simple, reliable, and effective. The pairing of an M16A1 upper receiver (without feed ramps) and an H&R-marked M16A2 lower provides a historically accurate configuration that collectors and enthusiasts will appreciate. Meanwhile, the 14.7" barrel, pinned and welded to a compliant 16" overall length, preserves the original handling characteristics while meeting modern requirements.

Outfitted with a CAR-15 style stock, A2 pistol grip, and classic carry handle iron sights, this carbine offers a pure shooting experience rooted in tradition. Whether you're building a clone-correct setup or running it straight out of the box, the H&R 723 stands as a perfect blend of retro aesthetics and practical performance.
