Easy install, worth the money - KIDD Innovative Design Pull Weight Tuning Spring Kit For Ruger 10/22

Although you have to disassemble the entire fire control group, this isn't very difficult to install. Utilizes different colors of springs for desired pull weights. Pay particular attention to trigger springs orientations prior to disassembly to ease reassembly, taking a before picture isn't a bad idea. This mod saves a lot of money over purchasing an entire new trigger and while the modified factory trigger may not be as nice as a new high end trigger, it's much more cost effective and will satisfy most shooters.
