Spring replacement depends on several factors:
How compressed your shoot schedule is
Quality of springs
Maintenance (corrosion)
Most springs nowadays are pretty corrosion resistant, unless you buy basement-priced garbage from companies who love to whittle away at the margins by attacking the product.
For a high-volume AR15 in 5.56 NATO that is run regularly through a heavy shoot schedule:
Extractor spring every 2000-4000rds
Ejector spring every 2000-4000rds
Recoil spring every 5000-6000rds or when it shortens below the spec.
For a 6.5 Grendel shot maybe 50-100rds per range session, with quality springs, I doubt you'll ever need to change them unless you shoot thousands of rounds every 2-3 months.
