In the mid-1960s, Colt built something remarkable — and almost no one got to own it.

The 606 rifle was the first true heavy-barrel AR-15 ever produced. It carried a full 20″ heavy barrel with a three-prong flash hider, and a chrome bolt carrier — before heavy barrels were even a standard concept. Only a handful were ever made. Even fewer were ever fielded. For sixty years, it's been a ghost — a chapter in American firearms history that collectors could read about but never hold until now.

H&R is bringing the 606 back. Built to honor the original's legacy with the craftsmanship and standards today's shooters expect. The legend didn't disappear — it was waiting.
