The Liberty Fighting Trigger is the standard trigger for all our builds. It is a high quality, ultra reliable and CONSISTENT combat trigger. Where Mil-Spec triggers can vary between 6 and 9 lbs the LFT will always get you a pull between 5.5 and 6 lbs. Our triggers use high quality QPQ stainless Trigger and Hammer pins, full strength Mil-Spec springs, and come ready to install with a stainless slave pin that will come in handy for future builds.
