NAP Blood Runners problems?
 

Do you have trouble with the N.A.P. Blood Runners (Red)? Call NAP
if you have trouble with the screws falling out or loosening. This is a manufacturers defect! They will replace them with the black ones at no cost to you. Also they have an offer that if you have Blood Runners already, they will send you a practice Blood Runner broadhead.
