OK but it will not look good.

Open the Spartans_W,txt this will have a number in i.e. 3
This is the index of the weapon in the Weapons.txt file in the same directory.
Open this file and in the 3rd row you will get a series of numbers. The first four are coordinates we 5th and 6th have to do with the scaling of the weapon. these two last numbers would be 3, 1 change that to 5, 1 save and you are done.
