Delighted new owner in R1 Rifle Posted December 12, 2015 Agreed, I spent several years working in high tech metallurgy, cryo treatment is a major benefit. I'm also not convinced that heavy "bull barrels" have any real world benefit. A well engineered thin wall barrel can achieve stable heat-up on the first round. 3D computational thermodynamics make it possible to design for scenarios that were unthinkable just 20 year ago. I know this is sacrilege but Italian engineers deal in reality while Colt sells us tradition. I'm a biker so for me its Ducati v HD. One wins races, while the other needs an F150 to carry it home.
