I know about: Savage RemAge Blaser DTA My uses are Competition Target, Hunting and some Tactical Competition type may wind up in the mix. NO PISTOL GRIP ala AR15. So all DTA and AI types are out of contention. I really like the Blaser R8 setup but I'm not so happy with barrel selection. Actually it's twist rates. There are reports of Blasers in the .3 MOA range so I'm pretty sure it would work out but like lots of manufacturers they seem to specify slow twist rates. so Biggest thing I'm trying to avoid is proprietary barrels. Biggest thing on the wish list is field changeable.
