i still havent got my equipmet yet but 350$ is a good start to a rifle but 150$ for a secondary can shoot just as far and its easyer to practise manuvering. I wish i bought my secondary first seeing as i need one now XD. Though some of these guys may seem to be mad at you its only tough love so don't be to discouraged.
its good to start getting ur equipment ready before you hit 18. Your off to a good start now so keep it up.
