The Patriot Ordnance Factory 00457 Drop-In Single-Stage Straight Trigger is a factory-ready trigger upgrade for AR-platform rifles that prioritizes durability and reliability out of the box. With a 4.5-pound draw weight and straight trigger geometry, this POF-USA trigger delivers a clean, predictable break ideal for shooters who want a dependable upgrade without gunsmithing. The entire assembly—trigger, disconnect, and hammer—is forged from American A2 steel and Nitride Heat-Treated to 70 Rockwell hardness, ensuring both corrosion resistance and long-term strength under repeated firing.
Installation is straightforward: the trigger drops into your lower receiver as a complete unit, with no additional fitting required. POF-USA engineered the housing with hard coat anodized aluminum and fitted it with signature rubber urethane feet that keep the assembly locked in place and free from rattle. Every unit includes stainless steel KNS Precision Anti-walk Pins, so you get everything needed for a secure install right out of the box.
This trigger is purpose-built for standard AR-15 lower receivers and is not compatible with DPMS 308 lowers featuring straight trigger guards or Sig 716 platform lowers. POF-USA also does not recommend this trigger for use in 9mm PCC (pistol caliber carbine) platforms. If you're running a conventional AR-15 platform and want a single-stage trigger with premium materials and proven POF reliability, this is a solid choice for hunting, range shooting, or precision work.
