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 black/phosphured bolt & carrier assembly and extra 30 rnd mag preferrably or something else. Or I will sell for best offer, as long as I get enough to buy a decent BCA.http://usp8riot.com/images/boltcarrier.jpg
Edit: I paid $175 for the bolt carrier group as an option to my m4-gery upper and ordered it from model1sales.com but I don't want to rip anyone off. I think their price was a little high after looking at others. I may have it traded already but how's $140 sound?
