Great value!!
The combination of the reduced power trigger and hammer springs worked very well. My M2 had a trigger pull that was creepy and about 5.2 lbs. After installation of the springs the trigger still has some creep, but it is smoother. It also is a consistent 3.2 lbs and produced no failures in the 100+ rounds I've fired since the upgrade. Easy installation...inexpensive and effective. Doesn't get better than that.
