I have a 2 stage timney for my ruger precision rifle that came on the gun when I bought it. For the life of my I can't find any good Info on adjusting the 1st or 2nd stage and I'm not sending it back to timney and ducking around with that mainly because I need it. Has anybody adjusted there 2 stage trigger and could give a detailed explanation of how to do it, or link a video on how to do it.
