Having divested myself of some time and possessions recently I find myself with a hole to fill and would appreciate thoughts and recommendations from you fine gents:
.308 or .300 blackout (slight nod to the .308 as I already have ammo on-hand).
Compact (mostly so it's not a musket when I put the 7" AAC SDN-6 on the end of it)
Hunting rifle for kids (see suppressor) and me when I feel like it.
Budget = $500ish, used is fine if possible
Looking at the Ruger American Predator right now as the front runner.
Any thoughts one way or the other on caliber or other recommendations?
