AR Bolt --normal movement "feel/resistance" in bolt carrier

I've had my Colt HBAR for about five years and got used to very smooth movement of the bolt/gas rings assembly within the bolt carrier upon cleaning.

`Couple days ago I got YoungSon a Colt M4-style sporter for XMas which functions just fine. But I noticed a significant difference in the feel/resistance when reseating the bolt past the gas rings into the bolt carrier, and when moving the bolt back and forth when assembled.

The gas rings/setup otherwise appear normal, and the weapon had no stoppages over 50 rounds yesterday with either commercial bulk reloads or my own (69SMK/Varget/25.3/WWcase/CCI400).... But that bolt sure feels like things need to lap themselves in.

`Other's experiences with new/Colt bolt assemblies?

Gas rings wear. Shooters advised me to replace the gas rings when the carrier moves due to gravity when the assembly is placed on the bolt head.

At some point your AR will stop functioning when the gas rings lose compression.

Just like your automobile. Rings wear in those things too.
If I'm not shooting, I'm reloading.
