I own a vanguard in 223. Very accurate. I am going to be getting one in 30 cal in one way or another soon. They have proven their salt in my books with a good build right out of the box.
If you don't mind a few extra pack ounces, get a suppressor. Gemtech makes them in titanium. Put it in your pack. When your in place screw it on. Recoil is half that without one. Your ears will also thank you.
My most favorable part is you stay on target through your optics easier with the barrel tip weighted.
A suppressor and silencer are 2 diff things right?
