Handis are supposed to be more scope friendly. Rems have a weird 11mm dovetail for a scope and a tough to adjust iron sight (prob good for a truck gun though). The few Rems that I have handled have had tight actions, no external hammer (I see this as a neg), awful triggers, and that funky helical flute on their barrels. The barrels are supposed to be excellent shooters though. Hammer forged. I believe that the barrels are quite short, which again is a plus in a truck gun.
My local shop has been sitting on 2 Rems in 7.2x39 and .308 for months. Handis fly out of there within 2 weeks.
