My ORF ejector rounded off a bit also and did so quickly. It seemed to stop wearing after about 100 rounds. Im well into 1500 rounds now and it still ejects well and the wear has not gotten any worse. I have two more ORF receivers that Im building into rifles at this time and they both have minor issues that need to be dealt with. Bottom line is that ORF receivers are not IMI receivers and I dont beleive ORF will ever get it 100% right. I've seen several outstanding recommendations given to ORF for product improvement and all seem to have been ignored. When your the only game in town you don't need to be perfect. That being said, their receivers are very usable. I suspect that you ejector will be fine. Good luck anyway.
