All the features of the Tubb Precision CS AR-15 Hammer and Trigger Return spring set plus an ingenious means toward attaining an improved first stage pull weight in aftermarket two-stage triggers.
The Tubb Precision CS AR-15 "National Match" Trigger Return Spring provides an easy means to boost first stage weight, which makes it possible to lower second stage break weight, and easily stay within the 4-1/2 pound minimum for Service Rifle competition. Plus, as with all Tubb Precision CS Springs, you are ensured of trigger pull weight consistency, a critical factor for major events. Hammer Spring is included.
I installed the National Match Spring set on a Rock River Arms lower that had their two stage trigger. When I first received the RRA lower I polished the trigger components to smooth and lighten the pull. I thought I was happy with my results until I installed your spring kit. The trigger is now slightly heavier, but still well within my goal pull weight, but the two stage action is significantly improved. My goal in setting this AR trigger was to make is as similar as possible to my tuned M1 and M1A SOCOM triggers. Your spring kit finished the job for me.

Nice upgrade if u don't plan to change the trigger to a 2 stage. I did not notice much of a difference in the trigger pull still felt a little stiff, but I'll have to put a few hundred more rounds through it before I can really tell.
