I was personally hoping that the Rival Atlas would be smaller. Then it could be integrated into other guns easier. The Rival Kaos, for instance, would look cool with a minimized Atlas. It would have to be pretty small.
I called it! When I first saw the Doomlands Doubledealer, I knew that the stock would be able to hold two magazines. If it is comfortable enough, It will probably replace the Longshot stock integrations.
In conclusion, I am excited to see what Nerf modders do to these guns. Have a good day!
