The service rifle guys like it when their brass lands in one nice little pile right next to them, hence the reduced ejector spring power. A little bit of AR15 useful info:
The ejector spring and selector detent spring are supposed to be the same part #, so mark them when installing, and consider the one in your pistol grip as a replacement for the ejector spring when you change it out at around 4000rds. The main reason to service the ejector is due to brass shavings accumulation in the ejector channel, which will defeat the springs ability to compress eventually, causing FTEject malfs. A sharp extractor will make this happen more than a tuned extractor.
