Still with the cobblestone texture but at least later M60A3s had anti skid texture so it's not so bad.
The cupola is detailed enough inside to leave open, you should have a loader to make up for the lack of a honeycomb ammo rack.
With all the m60 "Dino riders" lurking these forums there will be no end of people to tell you what's right and wrong here. Like the gun barrel being fine as the real fiberglass shrouds could be very rough and uneven. That the barrel fits together just fine practically needing no filler. That after market gun barrels for the M68 are too smooth and missing all the tiny details.
That is indeed a kill light, the convoy light was a lot simpler didn't mount to the turret lift ring. There is a whole host of wiring and the sensor harness missing though.
Huge improvement over the ESCI, Tamiya and Academy kits. Get a dozen and do all the crazy markings my old Guard unit would chalk on them.
