My Ataman uses a free floating barrel, as well.
I thought the AAA Evols were tensioned, as are the EDGuns... At least the EDGuns that I have owned are tensioned, including the R3 Long that I currently shoot slugs with, all three .25 R5M and .25 R5 Super Magnum that I have owned but sold. Free floating - Red Wolf, Crown, Streamline, Boss, Royale... Yup!
