Firearm customization

[Firearm customization]

Are there going to be any firearm customization? example: changing barrels(example you bought a Glock chambered in 40S&W and you want to fire some 9mm so you buy a 40 to 9mm conversion barrel and install it) 

 

Would be fun to change parts (in both firearms and vehicles) same way as you do in that car mechanic simulator game on steam.

I am going to reside in a rural area and live off the grid. i hope theres going to be the ability to get your own electricity and water well. also hope there is going to be both old and new american pickup trucks to haul stuff with.
