I have a chrome bolt & carrier which I've shot about 110 rounds through. I've had the rifle for a couple months now and being all black, I just can't get used to the aesthetics of the chrome off-setting all the black of the rifle. The rifle shoots and has shot fine ever since I've had it. It is a perfectly functional bolt & carrier, and cleaned after every outing. I will trade for a preferrably new black/phosphured bolt & carrier assembly.
