Patriot Ordnance Factory FLAT Trigger: Precision in Tactical Gear

Precision triggers are the backbone of repeatable accuracy and dependable performance in any AR platform. Whether you’re building a competition rig, refining a hunting setup, or upgrading a tactical rifle for duty or personal defense, a consistent, crisp trigger pull makes the difference between a good shot and a great one.

PATRIOT ORDNANCE FACTORY DROP-IN FLAT

What the PATRIOT ORDNANCE FACTORY DROP-IN FLAT brings to your rifle

The PATRIOT ORDNANCE FACTORY DROP-IN FLAT is a single-stage, non-adjustable, drop-in trigger that ships pre-assembled for immediate use. It’s set to a solid 4.5 lb. pull weight — a practical choice that balances a crisp break with safe, controllable operation for competition, hunting, and tactical applications. The entire trigger group is housed in a Hardcoat Anodized aluminum assembly and features rubber urethane feet to help stabilize the unit in your lower and minimize wobble under recoil and repeated firing.

Materials and durability engineered for service

POF’s approach to durability shows in the metallurgy. The Trigger, Disconnect, and Hammer are carved from American A2 steel and Nitride Heat Treated to a 70 Rockwell case hardness, delivering impressive strength, wear resistance, and corrosion protection. Nitride treatment is proven to reduce friction and extend part life, which is essential when a trigger faces high round counts or harsh environmental conditions.

Housing and fitment

The trigger comes pre-assembled in a Hardcoat Anodized aluminum housing — a finish choice that resists abrasion and maintains appearance over years of hard use. Included are custom-fit stainless steel KNS Precision Anti-Walk Pins that accommodate both standard AR lowers and POF USA ambidextrous lower receivers. That plug-and-play fitment reduces the need for gunsmithing and ensures consistent alignment of the trigger group within your lower receiver.

Compatibility notes

Installation is straightforward: pull the rear takedown pin and the two trigger pins, remove the factory trigger parts, drop the complete system into the lower, and reinstall the pins. That process means most users can swap from factory parts to a precision drop-in in minutes. Important compatibility detail: the curved trigger does not work with DPMS 308 lowers that have straight trigger guards, or with Sig 716 lowers — double-check your lower style before purchasing.

Performance and user experience

With a 4.5 lb. single-stage pull, the PATRIOT ORDNANCE FACTORY DROP-IN FLAT is ideal for shooters who want a decisive break without the twitchy feel of ultra-light triggers. The pull weight is a good match for duty-style use, hunting environments where accidental top-offs must be avoided, and practical competition classes that restrict modifications. The rubber urethane feet and drop-in tolerances reduce lateral play, improving perceived crispness and follow-up shot precision.

At a price of $126.89, the unit sits in a competitive range for a high-quality drop-in trigger that pairs performance with durability. For many shooters who value time saved on installation and the peace of mind of serviceable metallurgy, that price point represents strong value.

Installation, maintenance, and safety best practices

Installation requires minimal tools and basic AR familiarity: clear the firearm, remove the rear takedown pin and the two trigger pins, extract factory components, drop the PATRIOT ORDNANCE FACTORY DROP-IN FLAT into place, and reinstall pins. After installation, function-check the safety and dry-fire within a safe environment to confirm engagement and reset. Because the internal components are nitride treated and the housing is hardcoat anodized, maintenance is simple: keep the unit clean of carbon and debris and use a light lubricant compatible with nitride surfaces when needed. Routine inspection of the anti-walk pins and overall fitment is recommended after the first 100 rounds and at regular intervals thereafter.

Who benefits most from this upgrade

Semi-automatic rifle owners who want a reliable, service-grade trigger without the complexity of adjustable systems will find the PATRIOT ORDNANCE FACTORY DROP-IN FLAT compelling. It fits operators looking for a robust, repeatable 4.5 lb. trigger pull, hunters who want a dependable break in the field, and competitive shooters who prefer a non-adjustable profile that conforms to event rules. Patriot Ordnance Factory (POF) has a reputation for engineering and quality manufacturing, and this drop-in continues that tradition with American A2 steel components and precise anti-walk pinning solutions.
