Regarding the first 3 mentioned:
Timney better than Rise.
CMC better than Timney.
I have the older Hiperfire Hipertouch 24C in my 15-22. Using the gray spring. Pull is a taint over 1.0 pounds. Very light. Gotta be careful. With my ARs, they all range between 2 and 4 pounds. Crazy thing is with all my ARs and this 15-22, the .22 had the best factory trigger. Right around 4.0 lbs. The others ranged from 5ish to 8ish.
