Trigger was fantastic but broke with about 300 shots. - Rise Armament Folds of Honor AR Performance Trigger

I loved the trigger it was almost as good as my Hyper and Timney Gold but the reset spring broke. They do have lifetime warranty but it's very inconvenient to hunt down those small allen head wrenches. I could only find one and tried to hold the other side and scratched my lower receiver. Such is life.
