Explore the heritage and performance of the H&R 607 series, rooted in the legendary Colt 607 carbine of the 1960s. First fielded by U.S. Special Forces during Vietnam, the Colt 607 helped define the compact AR‑carbine class. Now offered by H&R Arms Co., these receivers faithfully replicate the original 607 styling—using forged 7075‑T6 aluminum with partial fences, US‑property marks, and safe/semi/auto selector markings. Whether you're building a retro AR-15 with historical accuracy or simply seeking a top-tier lower, the H&R 607 line combines collectible authenticity with modern machining quality.
