416 California Compliant Questions

[FaceVex]

I accidentally ordered the California complaint 416 22.  It was just shipped and cannot be returned.  I’ve not received it yet but I’m curious if anyone knows the differences and if it would be easy to convert the stock to a standard stock or is it a specific weird California size?

i don’t mind the mag limitation as I can buy different mags. But I’m wondering if this is going to be a big difference and if I should just sell it. 
 

thanks,
