To overcome this CMD have produced the fume extractors in finely cast resin to allow the incorporation of details such as bolt heads, weld seams and other small details and each barrel muzzle is drilled out to a depth of about 10mm (1/2in), all this along with the nicely turned metal tubes makes for some excellent barrels.
The barrels come pre-assembled with the resin fume extractors in place so
no cleanup or assembly is needed other to fit the barrel to the target vehicle.
Each barrel is not designed for a particular kit but has the normal gun tube diameter at the breech end which will require some modification of the target kit. As the barrel diameter is correct this is usually internally on the target kit breech or mantlet parts.
