  1. Im in the processing of building my first AR which started as a .556, however I have decided to finish it as a .22lr for now. I plan to do a dedicated .22 upper and eventually build a separate .566 upper. I currently have an Aero lower with a buffer tube kit, and I plan on just buying a completed PSA .22 upper. I want to buy a nice drop-in trigger, maybe something like a 1 stage Timney. I heard lighter triggers, like 3lbs, have issues with .22. Is there a good trigger option that can fire .22lr AND .556 with no malfunctions?
