It’s worth $200 but not $300 - Bear Creek Arsenal BC-15 5.56 NATO 16in Right Side Charging Upper Receiver

The fit and finish on this upper isn’t great and only runs good when it’s dripping with oil. I got it on a crazy good sale for $200 and it’s probably worth that but not worth regular price. I’d doesn’t work flawlessly and isn’t super accurate but it works when freshly cleaned and oiled and for that price it’s hard to complain about that.
