The Dual Cycle Rifle (DCR) was a 5.56×45mm NATO caliber revolver-type assault rifle that used a unique gas operation with a Webley-Fosbery-type grooved cylinder enabling three-round bursts at a rate of 4,900 rounds per minute. [1]
Overview
The Dual Cycle Rifle used a mechanism that fired a three-round burst from a single barrel at approximately 4,900 rounds per minute. This was assisted by a revolver-type cylinder with three-round chambers on half of its side. The rifle mechanism used a cam and follower mechanism. The cam path controlled the basic function of the rifle action to obtain the highest rate of fire with minimal operating rod velocities and provided the ability to fire the three-round bursts. The three rounds were loaded simultaneously into a chamber and the chamber indexed to fire each round before extraction. This eliminated the need for a full-stroke cartridge handling mechanism.
