HaloMods "Classic" Read-only Archive

I have a question about injecting bitmaps with remodeled weapons. I injected the model of the battle rifle in over the assault rifle and it looked like crap. I didn't change the bitmap and it is still all mess up looking. I tried to change the bitmap with one of the mod where i got the battle rifle from and it still looked like crap.
If any1 kno plz reply quick. TY

did any1 get a modified model to look right in the xbox version? As in the skins looks right or have a decent look to it.
