The NiB carriers definitely are easier to clean and have a natural lubricity that decreases the need to run a dirty AR soaking wet.
Spare parts for an AR (assuming your gas key is properly staked):
Bolt Firing Pin (2) Firing Pin Keepers Cam Pin Buffer Retainer and Spring (2) Extractors and Springs (with black O rings)
(The above are the parts that seem to fail the most often)
Next:
Trigger/Hammer/Disconnector with springs and pins Gas tube and pin (crush yours and it's a single shot) Charging handle with latch
ETA Long Term:
Action spring Full Lpk
