I just picked up the Eclipse and have only put about 200 rds. through it. I have been reading a lot about "factory recommendations" of changing the spring at 800 rds.. Does this ring true as the average or is it like when the eye doctor tells me to throw my disposable contacts away every two weeks whether I need to or not? Also, I need info on how you slicks are changing springs (i.e. heavier) and getting the guide rod back together without injuring the family pet with springs flying around the house at mach speeds. Any and all help is VERY appreciated.
