Service life on the HK P30 RSA is 20k rounds.
HK Lifetime Warranty is only in USA?
Hmm it's world wide I thought? Have never seen an Exception Disclaimer Disclosure in the wordage regarding the Lifetime Warranty. I was unaware...
I recommend using Weapon Shield as a lubricant, arrests wear and tear in high load areas of the HK.
Watch a few of his youtube videos, he an SAE Lubricant Engineer / Chemist, he developed Weapon Shield to be the benchmark.
