For those into variations, I noticed a change on The Black Series 6-Inch 74: Dengar's rifle.
• 1st version. Dark Charcoal colored rifle. Number "2" on side of gun. Date Stamp 82461.
• 2nd version. Gray colored rifle. No number "2" on side of gun. Date Stamp 82501.
I have a few of each so they are not one off changes, also had a couple people in my collecting circle check theirs and they had the same.
The first versions were found at GameStop and BigBadToyStore. The second version was sent out by HasbroToyShop.
Above is a side-by-side comparison photo, or you can visit the figure's page for a much larger view of each.
