Problems creating a range weapon

Hey all,

So i was trying to make a custom bow, made my own model and textures in blockbench but when i tried to use it inside of mcreator the mdoel didn't show up, it is a json file and that isn't the worst part of it, since i couldn't put in my model I thought to just use the default one for the time being but it just doesn't show up in-game, I know the arrow is there because it explodes upon contact with the floor like i set it out to do but it just won't show anything. Any tips?
