Would it be possible to create a new texture mod for the carbine rifle that removes the heat shield looking thing on the front grip?

When I try to install the ASI files required to use mods in openiv, It says I still need to install them, and when I go back to the asi page. It says to update all the mods, even when I click update on all of them and reopen the asi page, It still says they need to be updated. I really need help on this, I've already tried reinstalling OpenIV and it didn't work.
