Hi,
First of all, im sorry if something on the post isn't understandable, im spanish, but ill do my best to explain my question.
ArmA 3 has right now a lot of attachments for the guns; i've seen from dlc to mods a lot of customization. But for now, the guns only have a few ways to be customizable.
I know that (for example) SPAR-15 is a shorter cannon version of the SPAR-17, so basically you can "customize" the barrel lenght (by changing weapon). But its something that i would like change myself; not by changing weapons, but changing the cannon's lenght. I don't know if this feature (and more, obviusly) will be added in a future update (I really doubt it) or in the next Arma game.
Thanks in advance
