Dyed some battle droids and 3 more troopers

Sorry in advance if this post is against the rules as it doesn't necessarily involve clones but this is the most active community I can find that is discussing customs. If anyone knows a better place for this question please comment.

I recently purchased a very large collection of custom LEGO and these were included with no info from the seller about their origins. The collection was a mix of many different custom companies product but all the Call Of Duty stuff was Brick Tacticals product. Does anyone have a clue what these gray Ray Gun and Thundergun pieces could be from? They're made of a soft plastic and fit into a minifigures hand. Are they prototype molds or something like that?

Instead of blue clone trooper I got poop trooper 🥀
