What is the overall length of the M4A1 service rifle with the buttstock closed?

The overall length of the M4A1 service rifle with the buttstock closed is indeed 29.75 inches (756 mm). This specification is important for a variety of reasons, including ease of handling, maneuverability in tight spaces, and transportation considerations in various operating conditions.
