Maybe this is the cause of the delays in delivery - changing the barrel length to prevent flaring. Pretty complicated fix though, as it would require a total re-design.
Do the end of the barrels look to be an add-on part or a single barrel?
Hi James
Looks like single barrel to me: no obvious added on bits. I'm not clear on why a total redesign would be necessary providing the objectives stayed in the same place, although new moulds would certainly be needed for the magnesium barrels and rubber armour.
