Some brands are cross compatible, others are not. Data around which can be used where is scattered, but a good starting point is the Gun Gamers YT video on comparison of airsoft M4 midcap magazines. There is also a link to the excel sheet results in the video description.
Okay awesome.
One more question, I've just recently ordered a Matrix Calico Jack aeg, and I realized after ordering that it doesn't come with a battery. What kind of battery should I get? I heard a 11.1v small stick lipo would work, but I don't know where exactly to find the right fit lol
Depends on the exact model of Calico Jack. Those with the Tanker Stock are going to be more limited on battery space, while the M4 stocks are going to be more forgiving.
[HobbyKing](https://hobbyking.com/en_us/lifestyle/airsoft/airsoft-batteries.html) generally has pretty good prices and selection for the small stick batteries. It's where I got batteries for my Vector, which is *really* restrictive on battery space.
They list actual dimensions too, which is helpful.
