I have used JP yellow springs in many AR's, but never in a .22lr, I think you will get light strikes as a rimfire generally needs a harder strike to fire than centerfire. A Velocity replacement may be a better option, but will set you back $135.00. They feel as good as a Timney at half the price. 3lbs clean as ice.

The JP's may work though, may only be able to use trigger spring but not hammer spring, but is a small gamble, but wont lose much!

Also JP has a red spring option, for SD purposes, not quite as light, maybe 5lbs for red and 4 lbs for yellow

Good luck
