The Savage will give you a det center feed mag, a simple self adjustable trigger, and lots of options for swapping barrels in the future. Likely less money too. Certainly alot less money to tweak in the future.
The R5 is Milspec and we all know that milspec is the best thing since sliced bread. Without "milspec" you'll be lucky to hit the ground with three shots.
Got Milspec?
