I too shoot the R15 in 223 for all my yote hunting! Decent weight, easy to handle, and very reliable shooting 55gr. I have mine topped with a Vortex 6-24x50 that my fiancé bought me for Christmas a couple years ago.. If I chose the scope, I would keep with a lower power like I had it on before as when I call coyotes they are rarely over 100yrds.
