H and R 723 Features The H and R 723 is built around a 4150 chrome moly vanadium barrel with a chrome-lined bore and a 1-in-7 twist finished in a durable parkerized coating that matches the period-correct aesthetic. The carbine-length gas system and M4 barrel extension keep cycling reliable while a rifle-height gas block and A2-style front sight base preserve the classic profile of the era. A full-auto profile bolt carrier group runs a Carpenter 158 steel bolt for long service life and the standard mil-spec trigger group delivers a familiar predictable pull. The forged 7075-T6 lower and upper are hard coat anodized to mil-spec tolerances for corrosion resistance and durability. The carbine-length 7-hole handguard with heat shields protects the shooter s support hand while preserving the slim retro profile that defines the 723 pattern. A 6-position CAR-style stock on a mil-spec buffer tube lets the shooter adjust length of pull and the A2-style pistol grip keeps the manual of arms familiar to any AR shooter. The integrated scope mount atop the M16A1-pattern upper accepts optics or iron sights without further modification. At 6 lbs and a 32 overall length this H and R 723 offers a lightweight historically accurate carbine platform for collectors retro builders and shooters alike.
