I did a fair amount of research about the chrome lined, Chrome Moly Vanadium barrel that came with my PSA M4 Carbine and was satisfied that it was more than adequate for my application. The CMV metal stock is just another metal blend used for barrels that fall between the 4140 and the 4150 (higher carbon content) high tensile steels. The addition of vanadium to the 4150 "blend" just gives it a unique quality prefered for barrel manufacturing. There are CMV barrels that are not chrome-lined, and some with the chrome lining. So not only is this PSA barrel of high quality material, it is also CL for improved corrosion resistance....Win/Win!!
