Diemaco C7A1 vs Colt M16A4
This video compares the Diemaco C7A1 and Colt M16A4, highlighting Canada's early adoption of the flat-top upper receiver and Weaver rail system around 1990, predating the US military's 1913 Picatinny rail. The C7A1 is praised for its practical A1 rear sight, full-auto capability, and cold hammer-forged barrels, contrasting with the M16A2's range-focused design. The discussion delves into the history and standardization of the 1913 Picatinny rail, crediting Dick Swan with its development and dimensions.
