Looking good vaughan, as for the machine guns ,it looks as if they are just straight with no perforations or anything so you could just cut them off and replace them with brass tube, I usually do this on most of my builds as it looks better, is a bit stronger than plastic and you havent got any nasty seam lines to tryand clean up ,plus its easier to add them at the last stages of the build. You can get it at the online shop, i should say about a 1.3mm -1.5mm dia should do it ,remember to cut it with a stanley knife blade on a hard surface with a rolling action,this avoids flattenning the ends which is what happens if you try to snip it with pliers etc. hope this makes sense, cheers tony
