Introducing the MK18 Crane Spec Series

Andro Corp’s Take on a Legendary Platform

The MK18 Crane Spec Program began in the early 2000s when the U.S. Naval Surface Warfare Center—Crane Division—set out to develop a compact, highly reliable carbine tailored for special operations forces. The “Crane Spec” designation reflects the rigorous standards and extensive testing performed by Crane Division, resulting in a platform renowned for its durability, modularity, and adaptability to any mission.

A defining feature of the MK18 platform is its original intent for suppressed use. Designed from the ground up to run reliably with a suppressor, the MK18’s gas system, barrel profile, and component selection ensure optimal performance, reduced blowback, and consistent cycling—whether suppressed or unsuppressed. This focus on suppressed operation is a core part of the Crane Spec legacy and a key reason for its legendary reputation among military and law enforcement professionals operating in demanding environments.

As the MK18’s popularity grew, so did the demand for civilian and commercial variants that honored the original Crane specifications—especially among enthusiasts seeking a platform that’s not just “suppressor compatible,” but truly optimized for suppressed shooting.

At Andro Corp Industries, we take the Crane Spec legacy seriously. Our MK18 Crane Spec Series of firearms, complete uppers, and barrels are engineered and assembled to meet or exceed the original standards set by Crane. Each component undergoes rigorous quality control and testing to ensure flawless function, accuracy, and reliability—especially when running suppressed. Our commitment to American-made craftsmanship, customer service, and technical expertise means every Andro Corp Crane Spec product delivers the performance and dependability you expect from a true Crane Spec build.
