If you are looking for a bolt-gun, either the Savage 110 or Remmy 700 topped with decent glass will do you.
But, why? You are already familiar with the AR platform, why not just step up to an LR-308/AR-10 offering and go with what you know? 300 yards is a chip-shot for either of the DPMS or Armalite .308’s. Barrel options, optics, triggers, furniture are just as varied for the .308/7.62x51 as they are for the .223/5.56x45.
Also, “patrol carrying” an AR on an extended stalk would be easier than doing the same with a full on bolt-gun/deer rifle. At least, from doing various types of field training on my own, I’d rather tote my AR than my Winchester.
Eugene Stoner’s little AR platform was originally designed around the .308 caliber round.
Just a few things to consider. ;-)
As for glass, depends on budget. If you can afford it, and are SERIOUS about it, US Optics/Nightforce/Leupold/Nikon. In that descending order. If not, find a decent Burris or “Cabelas” branded optic with the features you want and enjoy.
DC —
Were budget not a concern, I would go with an AR-10 AND a 700 or similar. Period.
As I work through AFOC/SHTF scenarios, I see ‘patrolling’ done with an AR-15. I may be wrong, YMMV. AR-10 more for static defense in depth.
there’s another variable - the “grey man” — where a hunting rifle form factor attracts less negative attention than an AR does. You and I know better, but... I actually do take the “grey man” factor into account here.
Good advice though, and thanks.
