For those that like to collect variations, I just noticed there is a paint variation on The Black Series 6-Inch 101 Cara Dune's Heavy Blaster Rifle.

1st release (Early Date Stamp) - Rifle is gun metal in color.

2nd release (Later Date Stamp) - Rifle is dark charcoal in color.

Found multiples of each at Target and Game Stop the past few days. You can see a side by side above.
