First of all let me say that I love the Knights trigger (I have the full auto version that I use with a RDIAS)
Second, let me say that it has Failed me.
It worked great for 1000's of rounds then.. it did Not work in semi. Fire the first round in semi and then nothing would happen no first stage, no second stage, NO bang. Swich to full auto, worked fine, switch to semi, one shot and then nothing. It stayed on the disconector. The problem was Set Screws, I think the trigger came locktighted from the factory but apparently I somehow managed to disolve the stuff. I used Tetra for a while then switched to Militech 1, or maybe it was that one time I used gunscrubber?
Anyway, the trigger caused a falure to fire for me.
Will I continue to use it? Yes, I really like it, I think its bennifets outweigh its limitations, however, I would practice some monitoring if it was in a SHTF rifle
