If you're abusive with your rifle, like heating it rather fast, or lazy with cleaning, then a chrome lined is really nice. I fit the above descriptions with my AR, and it's really really nice. /ubbthreads/images/graemlins/grinning-smiley-006.gif
It all depends on what you want and are expecting.
If I was shooting for scores or reaching way out for prairie poodles, then I'd stay away from chrome lining.
