I would talk to Ritch. He seems to fill those needs easily. There are cheap bull barrel uppers out there but there is a really big reason for that and it does reflect on target size too being a big reason.
Groups size has a lot to what you feed it. Picking XXX bullet can sometimes disappoint while other times it causes nary a ripple. If you are saving fur the choices are more limited but if it is masticated trees the choices are almost endless.
