No. Would that be because they are wrong, or because they are plastic?
It's because they are incorrect. PSC took a shortcut with this, and provided only one 75mm KwK40 barrel. The F2 version had a single baffle muzzle brake, which was round rather than cylindrical, with only one baffle (obviously). The kit supplied barrel as the double baffle muzzle brake with 2 baffles... Also the F2 mounted the KwK40 75mm L/43, whereas the barrel is for the L/48 version. The difference is close to 4mm in this scale.
If you're interested in the late version of the F2, the turret vision ports on the sides should be removed (very easy to do), as well as the flare gun ports on the hull hatches (not as easy to do -- it's the detail in the middle of the hatches). It might not be a bad idea to remove the box on the rear of the hull plate, which I believe is for the smoke grenade discharger, especially for later versions (as these mounted smoke grenade launchers on the turret sides -- not included in the kit -- but would later be removed due to vulnerability to combat damage and replaced with smoke bombs launched from the Nahverteidigungswaffe on some Hs and most Js).
