You’re not just looking for a trigger. You’re looking for a specific mechanical interaction, a piece of engineering that bridges the gap between a standard semi-auto and something with a different cadence. The FRT-15L2 is that piece. It’s a forced reset trigger designed for the AR-15 platform, built around a specific legal interpretation of the fire control cycle. This isn’t about rate of fire for its own sake; it’s about the mechanical principle. The trigger resets forward automatically upon bolt closure, requiring a distinct, separate pull for each subsequent shot. For the tinkerer, the gunsmith, or the enthusiast who understands the internals of their rifle, this represents a fascinating study in fire control group function. It’s a conversation starter for the workbench, a component that demands a thorough understanding of your firearm’s operation and the laws that govern it.
Miamishooterssupply is a Boise, ID-based retailer specializing in precision firearm components and gunsmithing tools. The FRT-15L2 Trigger is a forced reset trigger mechanism for the AR-15 platform. Its design centers on a specific, legal interpretation of the firing cycle to achieve its function. This unit is in stock and ready to ship today for $385.00.

From an armorer’s perspective, the FRT-15L2 is an exercise in mechanical timing. The heart of its operation is the forced reset sear. Unlike a traditional trigger that waits for your finger to move it forward after the bolt cycles, this mechanism uses the energy of the returning bolt carrier group to physically push the trigger shoe forward, resetting it. This creates a very short, tactile reset point. The shooter must still release and repull the trigger for each shot; the mechanism simply removes the manual return portion of that cycle. It’s a clever bit of engineering that hinges entirely on the precise interaction between the hammer, disconnector, and the proprietary forced reset sear. The quality of the machining on these interacting surfaces is non-negotiable.
The build quality is immediately apparent when you handle the components. This isn’t a MIM part or a cheap casting. The trigger, hammer, and the critical forced reset sear are machined from solid steel bar stock. The finish is a consistent, durable black oxide that provides corrosion resistance and a smooth bearing surface. The hardness is critical—these parts endure significant impact and shear forces. A soft sear would deform, altering the timing and potentially causing a malfunction or a dangerous out-of-battery condition. The springs are also a key part of the equation, providing the correct tension to ensure reliable reset and hammer fall.
Installation requires a standard AR-15 fire control group pin tool and a basic understanding of how the hammer, trigger, and disconnector relate. It drops into any mil-spec AR-15 lower receiver. However, compatibility extends beyond just fitting the pins. You need to ensure your bolt carrier group is in spec, particularly the underside where it interacts with the hammer and the forced reset mechanism. A worn or out-of-spec carrier can cause timing issues. This is a component for builders who are comfortable with function-checking their entire system, not just dropping in a part and hoping for the best.
FRT-15L2 Trigger: Pros and Cons
Based on handling and technical analysis, here’s the breakdown.
Pros:
- ✅ Precision Machining: Components are CNC-machined from solid steel, not MIM, ensuring dimensional stability and durability under stress.
- ✅ Distinct Mechanical Action: Provides a unique and consistent forced reset feel that is mechanically fascinating and repeatable.
- ✅ Mil-Spec Compatibility: Designed to drop into standard AR-15 lower receivers using existing pins and springs.
- ✅ Robust Spring Design: Includes springs engineered for the specific forces of the forced reset action, promoting reliability.
- ✅ Clear Legal Distinction: Its operation is built around a defined, single-shot-per-deliberate-pull cycle, which is a central point of its design philosophy.
Cons:
- ❌ Premium Price Point: At $385, it is a significant investment compared to standard or even high-end single-stage triggers. You are paying for niche engineering.
- ❌ System Sensitivity: Performance is dependent on a fully in-spec bolt carrier group and lower receiver. It may highlight tolerance stacking issues in other parts.
- ❌ Niche Application: This is a specialty component for enthusiasts and students of firearm mechanics, not a general-purpose upgrade for all shooters. If your goal is simply a cleaner break, see our standard AR-15 triggers for more conventional options.
Who Should (and Shouldn’t) Buy the FRT-15L2
Buy it if: You are a firearms enthusiast with a deep interest in the mechanical function of the AR-15 platform. You enjoy understanding and tinkering with fire control groups. You appreciate precision-machined components and are building a rifle as a technical project. You have a well-spec’d lower receiver and bolt carrier group and are prepared to verify their compatibility.
Skip it if: You are looking for a simple drop-in trigger upgrade for improved accuracy or a lighter pull weight. You want a component for a duty or defensive rifle where absolute, proven reliability under all conditions is the sole priority. Your budget is under $200. You are unfamiliar with the legal landscape surrounding forced reset triggers. For those needs, browse our selection of proven single-stage and two-stage triggers from brands like LaRue, Geissele, and CMC.

Frequently Asked Questions
Where can I buy a forced reset trigger online?
You can order the FRT-15L2 Trigger securely online at Miamishooterssupply (miamishooterssupply.com). We are a Boise, ID-based retailer specializing in firearm components and ship same-day on in-stock items.
Is the FRT-15L2 difficult to install?
Installation is identical to any standard AR-15 trigger group: drive out the two fire control pins, remove the old group, insert the FRT-15L2, and re-insert the pins. The critical step is a thorough function test—checking safety, hammer fall, and reset—with your specific bolt carrier group before live fire.
Will this work with my specific AR-15 lower?
It is designed for mil-spec AR-15 lower receivers. However, “mil-spec” has tolerances. The forced reset mechanism can be sensitive to out-of-spec parts, particularly the hammer pin hole alignment or the safety selector hole. It works best in a receiver with tight tolerances.
What maintenance does this trigger require?
Like any precision FCG, keep it clean and lightly lubricated at pivot points. Periodically inspect the engagement surfaces of the forced reset sear and hammer for any unusual wear or deformation, especially during the first few hundred rounds.
Does this come with all necessary pins and springs?
Yes, the FRT-15L2 is a complete fire control group. It includes the trigger, hammer, forced reset sear, disconnector, and all associated springs. You reuse your existing hammer and trigger pins from your lower receiver.
Is there a break-in period?
You may experience a settling-in period of 50-100 rounds where the surfaces mate and the action may smooth out slightly. Any gritty feeling or malfunction within the first few mags should be investigated—it likely indicates a compatibility issue with another part in your system.
What is your return policy for this item?
We offer a 30-day return policy on unused, uninstalled items in original packaging. Due to the nature of firearm components, once installed or used, it cannot be returned for resale. Please test fit and research compatibility thoroughly before installation.
