As above. Once a year? Every X thousand rounds? When?

Thanks,

Rick

I'm not sure. I have the MacFarland 1 piece that I took off after about 700 rd. It measures 0.503" OD, but the RRA original 3-piece gas rings measure larger than that and they're tighter.

My guess is that if your rings measure smaller than 0.500" OD, it MIGHT be time to swap them out.

I've only replaced one set but can not tell you what the round count was. It was on a bolt that was in very good shape. Used it for a postban build. It did not have that snug feeling to it when you pushed it in and out of the carrier while assembled. When it came time for live fire, instant FTEx. Changed the gas rings and it run well ever since.

Do the gas ring check...
Field strip. Clean bolt and carrier. Insert the bolt into the carrier, being sure it is seated all the way to the rear. Hold the end of the bolt on the lugs and see if the bolt will support the weight of the carrier. If it will not, replace the rings.

Rings don't really wear out that fast. However, when in doubt changed them. Rings are very cheap.

Thanks, all.

I will do the gas ring check method as basic maintenance check and may replace rings if/when/as other maintenance issues come up. I feel like I have a better idea of what to look for.

Thanks to all who have replied.

Regards,

Rick
