I current have 2 AR's. Both have RRA 2 Stage NM Triggers. I'd like to upgrade the pins to the new KNS Gen 2 Mod 2 Anti-Rotation pins. I believe I have read that the pins that come with RRA's 2 stage trigger are slightly larger than the standard pins. I do know that RRA lists them as a different part number. I assume that means that I should buy the 0.1555" pins instead of the 0.154" pins. Is this correct? Also, is there any issue with the 0.1555" pins working with the RRA 2 stage trigger? Thanks in advance for all the help.
