The Patriot Ordnance Factory (POF-USA) drop-in single-stage flat trigger is built for AR platform shooters who want a clean, consistent pull without the complexity of adjustable mechanisms. This 3.5-pound trigger ships fully assembled in a hardened aluminum housing with integrated rubber feet, so you can install it and get to work—whether you're prepping for competition, zeroing a hunting rifle, or running a tactical setup. No gunsmithing required.
POF's commitment to durability shows in the materials: the trigger, disconnect, and hammer are forged from American A2 steel and Nitride heat-treated for superior strength and corrosion resistance. The package includes KNS Precision anti-walk pins (stainless steel, custom-fit) compatible with standard MIL-spec AR lower receivers and POF-USA ambidextrous lowers. The black and red finish pairs function with visual appeal on the receiver.
A flat-faced trigger appeals to shooters who prefer direct finger contact and precise trigger control, especially under rapid fire or precision work. The single-stage design eliminates creep and over-travel surprises, delivering the same break every time you press. At 3.5 pounds, the pull weight sits in that sweet spot—light enough to reward trigger discipline, heavy enough to resist accidental discharge during normal handling.
Note: this trigger is designed for standard AR and POF ambidextrous receivers with MIL-spec parts. POF does not recommend use in 9mm PCC carbines, and it will not fit DPMS .308 lowers unless they conform to MIL-spec dimensions.

Yes, if your lower is a standard MIL-spec AR platform receiver or a POF-USA ambidextrous lower with MIL-spec parts. The included KNS anti-walk pins are custom-fit for these applications. It will not work with DPMS .308 lowers unless they use MIL-spec components. POF does not recommend this trigger for 9mm PCC carbines.
The trigger comes fully assembled in its aluminum housing with rubber feet attached, plus KNS Precision stainless steel anti-walk pins sized for your compatible receiver. No additional parts or tools are required to install it.
No. This is a single-stage, non-adjustable trigger with a fixed 3.5-pound draw weight. Once installed, the pull weight and reset cannot be modified.
A flat face provides more surface area for your finger and allows for more direct contact with the trigger, giving you enhanced control and consistent trigger press. Many competition and precision shooters prefer flat triggers for this reason.
