POF Drop-in Trigger Assembly 3.5lb KNS Pins included

The Patriot Ordnance Factory POF Drop-in Trigger Assembly 3.5lb with KNS Pins included is a single-stage, non-adjustable drop-in trigger built for operators demanding immediate deployment without gunsmithing. The 3.5-pound trigger pull weight offers a balance between precision and speed suited to both tactical operations and competition shooting environments. Pre-assembled in hard-coat anodized aluminum housing with integrated rubber urethane feet, this trigger assembly drops directly into compatible platforms and performs out of the box.

The internal components—trigger disconnect and hammer—are machined from American A2 steel and nitride heat-treated to 70 Rockwell case hardness, a specification that translates to superior corrosion resistance and durability under sustained use and harsh environmental conditions. This hardness standard is critical for reliability in salt-air, extreme temperature, and high-round-count training scenarios. The included custom-fit stainless steel KNS anti-rotate pins eliminate the most common point of failure in drop-in trigger designs, preventing unwanted movement that can degrade accuracy and trigger consistency over time.

This trigger assembly is engineered for shooters and tactical professionals who need immediate trigger upgrades without full lower receiver replacement. Law enforcement operators running training cycles, military personnel preparing for deployment, and competitive shooters seeking reliable trigger performance all benefit from the drop-in convenience and verified component quality. The 3.5-pound trigger weight provides control during precision shooting while remaining light enough to support rapid, accurate follow-up shots in defensive scenarios.

Patriot Ordnance Factory specializes in precision components designed for professional and civilian operators. The POF trigger line is recognized for component-level quality and dimensional consistency. Buyers selecting a POF drop-in trigger are investing in tested compatibility and known performance rather than experimental designs.
