Rifles: Procurement

Question

To ask His Majesty's Government what steps they are taking to ensure that the calibre of the rifle selected under Project Grayburn is the same as the calibre for the light machine gun selected under Project Troubler.

Answer

A review of performance requirements and technical solutions is ongoing as part of the concept phases for Project GRAYBURN and Project TROUBLER. Interoperability, (including calibre) with other in service weapons will be considered as part of this process. Commonality across users in the British Army is important but must be informed by the individual user requirements of each project, which includes consideration of NATO and wider international interoperability.
