On the one hand, this wasn’t a total surprise. Amazon has had exclusive repaints of the Nerf Strongarm, Disruptor, and Hammershot blasters before this. They like waiting a few years after popular blasters have released, and getting new colors to lure in the impulse buys and collectors! Not to mention the lack of Kronos blasters on store shelves currently; new sources of base blasters for mods like the Kronos Mega XL Conversion Kit are appreciated!
In any case, here are the links for the various blasters, in their unique new color schemes. Even if you’re only into stock blasting, the Kronos is by far one of the best sidearms you can find!
