After Market Machineguns?

Tamiya makes 1/35 weapons sets. avaliable from Squadron and others.
I'm sure there others.

Claymore is correct; the Ma Deuce in that set has a separate barrel. There was a company a while back that made EXCELLENT weapons and ammo boxes in brass... I don't know if they are still around, but they were VERY nice.

Would those be the .50's from Collector's Brass? Have one here but I think it's a little oversized, but it is a great looking piece of work. I got mine from VLS a number of years ago.

P.S. Did those hatches get to you yet Jason?

AFV Club makes a great injection .50 cal kit.
Also, an Aber M4A1 Sherman PE set I bought a while back had an amazingly thorough PE fret for that gun as well. I'm not sure if they sell it seperately (they oughta!), but check it out.
