Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the potential impact of adopting the 6.8mm calibre on the personal weapon system infrastructure of the Army.

I refer the hon. Member to the answer I gave on 28 April 2025 to Question 45196, which explains that Project GRAYBURN is in its concept phase with the aim of identifying and understanding capability requirements. As part of this phase, various rifle calibres are being considered. The implications of a potential calibre change, including infrastructure, will be balanced against performance requirements.
