Bryant Ridge's Analysis:
The Colt AR-15 A4 (CR6700A4) represents a faithful civilian rendition of the military-issued M16A4, blending Colt’s historic role in the evolution of the AR platform with modern factory precision. Colt has been central to the AR-15 story since the early 1960s, when it acquired rights to Eugene Stoner’s original design from ArmaLite and began producing the M16 for the U.S. military. Over the decades, the AR-15 has evolved into one of the most influential and adaptable rifle platforms in the world, praised for its lightweight construction, modularity, and combat-proven performance. Colt's continued production of semi-automatic variants like the CR6700A4 not only preserves this legacy but reinforces its commitment to both civilian shooters and military heritage. The CR6700A4 is chambered in 5.56 NATO and features a 20" chrome-lined, government-profile barrel with a 1:7 twist rate—ideal for stabilizing heavier bullets. It utilizes a rifle-length direct impingement gas system and comes equipped with classic military-style furniture, including an A2 fixed stock, A2 front sight, removable carry handle, and standard handguards. The upper and lower receivers are forged from 7075-T6 aluminum and finished with a hard coat anodizing, maintaining mil-spec durability. This model also includes an optic-ready flat-top upper and drilled rear for users wanting to modernize with glass, while staying true to the M16A4's roots. Whether appreciated as a historically accurate platform or as a functional, full-length rifle, the Colt AR-15 A4 offers excellent reliability, mild recoil, and consistent accuracy. It is especially well-suited for distance shooting, military-style training, or collectors seeking an authentic representation of the last generation of the M16 service rifle lineage. As Colt continues to uphold its place in the AR market, the CR6700A4 stands as a tribute to the platform's enduring design and the company’s storied role in American firearms history.
Return Policy:
