Build and Shoot

So I downloaded a Ak47 skin (Don't remember who) and it appears too small. The person that made that skin is not active anymore so no way of him fixing it. So I attempted to go into the code and change the third person size. I am having some troubles finding this code and was wondering if you guys can help. This is just for personal use, I am not claiming it is mine or uploading the weapon mod itself.

READ. THE. F-KING TUTORIALS FFS, your issue is covered in them.
Btw,
Matrix4 mat = CreateScaleMatrix(0.05f);
0.05f is the scale, try increasing it.

also if model appears in wrong position, mess around with
mat = CreateTranslateMatrix(0.35f, -1.f, 0.0f) * mat;
