Glad you are enjoying it and Thank's for the response!
Custom Turrets, I don't have any current plans for this I am not a good modeler and don't have any current ideas for how I could address this but its something I could look into in the future for a project.
Larger Magazine Sizes, This I could do for the AR, AK, L115, and Glock respectively making them basically double there current magazine sizes if you maybe craft 2 of them together or something along those lines. It's worth looking into for further progression on the manufacturing side.
I also do need to refine this mod for space age I have found some issues with the space age expansion with crafting specifically the iron sticks can be unobtainable before unlocking the gun crafting making it so you cannot craft the guns without unlocking further tech. Also the Glock was added last minute and never really fully tested with tech and has no tech tree at all. This could be moved into just locking the AP and Urain ammo to when you unlock the rifle ammo's as well.
This was an old mod from before space age even that I just uploaded on a whim to make it easier for me to download it and play with friends so I'm glad someone else is enjoying it. :)
