Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the potential benefits of adopting a short stroke piston operated system rather than direct gas impingement for any of the rifle variants tendered for development under Project Grayburn.

Project GRAYBURN is currently in its concept phase. An important output of this phase will be the definition of user requirements, covering the full range of performance characteristics, including calibre and operating system.
