It’s more the forward support for the barrel (that has a thicker area that sits just inside the front of the barrel jacket) with holes drilled through it so that air can cool the rear end of the barrel too. But yes, the holes are often very shallow on plastic guns, so drilling them out is definitely an improvement.I took the time to drill out (what I think is) the cooling jacket

I'm glad of all the responses as I always doubt myself at this stage. I'll push on with it as it is, if worst comes to worst its an AFV, I'll slap on some mud.
