So after educating myself a little bit on here, I decided that I should swap the RRA 2-stage trigger on my AR out for a Geissele SSA-E if I wanted a nice trigger pull coupled with durability.
The trigger pull is quite nice, and function tests properly, though I haven’t had a chance to shoot it yet since the swap. I did notice that with the SSA-E installed, the FCG pins rotate when I press the trigger and the hammer falls, and the hammer pin rotates when I cock the hammer. The RRA FCG pins never did that because, as I recall, they’re slightly larger than standard to prevent that sort of thing. I lubed the parts per the instructions before installation, but apparently the parts are rotating the pins rather than rotating on them.
Having done some searching before I posted, it looks like the trigger manufacturer recommends against using KNS pins with the trigger, and consensus is that rotating pins aren’t going to walk out or wallow out your FCG holes, but I didn’t think that the pins were “supposed” to rotate. I wonder if I made the FCG holes larger with the RRA pins, and now I’d have to put those back in to lose the rotation.
I’m running a Defensive Edge (SLR-15) lower, FWIW.
