Based on other people who have had the RRA two stage trigger, it is a softer metal and wears down quicker than better quality triggers, like geissele.
Do yourself a favor and take a serious look at the ACT or QMS triggers and a jp enterprises trigger spring kit. These are still single stage triggers, but theyre already honed to remove the gritty feel of an AR trigger. And made by geissele as well .
And yes, you do need a properly staked gas key on any AR. The screws WILL back out, causing you to lose gas pressure, causing FTE and FTF issues.
