Thanks for your service CATM,,, just learned yet another DoD acronym !!
Given what you just said, take a long look at the Ruger American Predator in 223.
I have two, 243, 6.5 Cm and a 22 WMR Ruger American, & like them all.
The RAP is threaded, so either muzzle break or can ready..
Oh, almost forgot, my 243 RAP is the heavy duty stick I pull out of the safe when I feel the need for more predator power...
it wears a big 56 mm Vortex scope for low light purpose.
