Problemns with blockbench textures (itens)

so recently i added 3d weapons to my mod and some models came with errors, in just some parts of the weapons the bug texture and it looks weird like an old tv with statics

Here are some examples, I know that and probably something to do with the texture or the size of the models but they have intens that share the same model and only the texture changes (like ak47 and ak74) and they bug at different points

and here is the model inside the blockbench if it helps

think it is worth saying that inside the Mcreator laucher the textures work as promised
