Build and Shoot

I don't know why, but I download a rifle mod and for some reason this happens. I don't know if its the scope, but the rifle looks really small. Does anyone know why this happens?

Yep, here the 2 problems you got here: The model is not the correct one for OpenSpades 0.0.10 version, try doubling the dimensions of the model for it to show correctly in 0.0.10, next thing is I think it's not at the right polygon coordinates, or whatever you call it, but yeah, try comparing it with the default semi rifle model and see for yourself, that's at least what I can tell you from my experience with slab6.
