Picked up a Rock River NM 2-stage trigger kit recently in the EE. Arrived today and turns out it isn't a complete kit after all even though it was presented and confirmed as such. The trigger and hammer pins are missing. Not a big deal really but I read in the instructions that the RRA pins are over size as compared to stock. A posting on ar15.com showing detailed installation instructions (with pictures 
) confirmed it. Blatantly reproduced:
The Rock River trigger pins are slightly oversized from stock, and will require more tapping force to seat them than to remove the original ones. This is intended, as you do not want the pins rotating in the receiver... you want the trigger and hammer to rotate on the pins.
I've got a Stag Arms lower with the 0.156" milspec hole so I'm not getting confused with the larger hole Colts. My pins measure 0.154" by my crappy caliper.
Anyone have any experience with the RRA pins or have a set they can measure? I was hoping just to use my stock Stag ones.
