POF-USA's single-stage EFP Drop In Trigger System comes standard with a 4-pound pull weight. It is pre-assembled in a hard coat Anodized aluminum housing. Carved from American A2 steel, the Trigger, Disconnect, and Hammer are all Nitride Heat-Treated to 70 Rockwell case hardness for ultimate strength and corrosion resistance. When assembled, POF-USA's signature rubber urethane feet keep the unit snug in the lower receiver. POF-USA also includes stainless steel KNS Precision™ Anti-walk Pins with every trigger.
**Will not work with DPMS 308 lowers that have straight trigger guards or with Sig 716 lowers**
