The H&R Retro 723 5.56 NATO carbine is a semi-automatic rifle chambered in .223 Rem/5.56 NATO that recreates the late-1980s 723-style build (brand part no. HR51655133723), pairing an H&R-marked M16A2 lower with an H&R M16A1 upper for a period-correct transitional design between the M16A1 carbine and the later M4. The 14.7 inch barrel is pinned and welded with a muzzle device to reach the legal 16 inch minimum, so the rifle ships as a standard Title I firearm with a fixed CAR-15 style stock and A2 pistol grip. Iron sights with a carry handle round out the retro-correct package, giving collectors and clone-build shooters a solid foundation to run as-is or customize further. This carbine is built for shooters who appreciate old-school military rifle history in a lightweight, reliable 30-round platform.
