As the barrel is not currently designed to be interchangeable, I am extremely disappointed.
I can understand the thinking behind this, but it rather takes away one of the main characteristics of the Service rifle, and at the current estimated price it makes it an expensive half copy of the Mk.2 Webley Service Rifle, not to mention the lack of a peep sight.
I realise the models currently on show are prototypes, but would suggest a bit more thought needs to go into this project before the rifle becomes available for sale.
