But seeing how smoothly it functions now I’m not sure when I will start to see short-cycling of the bolt carrier.

Depends on the gas system length and the original port size in the barrel. It will run fine as the gas port erodes and overgasses the BCG, might see some wear from that. Once the barrel port and gas block port have opened up to were there are significant seal issues, then you'll need some new parts. A basic gauge pin set isn't expensive, you can check the port size yourself which is a good idea no matter who you get parts from.
