What Makes the FRT-15L3 Trigger Stand Out?
You’re looking at a piece of mechanical engineering that changes how you interact with your rifle. This isn’t about just pulling a trigger; it’s about managing the reset. The FRT-15L3 uses the firearm’s own gas system energy to force the trigger forward after each shot, as long as you maintain rearward pressure on the trigger. It’s a three-position selector: Safe, Semi, and FRT. In the FRT position, the forced reset mechanism is engaged. The tolerances are tight, the machining is clean, and it installs like any other drop-in cassette trigger. It requires a specific understanding of its operation to function correctly.
Key Features of the FRT-15L3 Trigger
- Three-Position Function: Safe, Semi-Automatic, and Forced Reset Trigger (FRT) modes provide clear, selector-defined operation.
- Drop-In Cassette Design: Installs into a standard AR-15 lower receiver using the included pins, eliminating the need for individual springs and hammers.
- Forced Reset Mechanism: Utilizes gas system energy to positively push the trigger forward to its reset position after each shot when pressure is maintained.
- Precision Machined Components: Manufactured from hardened steel and aluminum to withstand repeated cycling and maintain critical tolerances.
- Distinct FRT Feel: Offers a tactile and auditory reset that is noticeably different from a standard semi-automatic or binary trigger’s operation.

FRT-15L3 Trigger: The Good and The Honest
Pros:
- ✅ Provides a unique and distinct forced reset trigger function not found in standard or binary triggers.
- ✅ Drop-in installation simplifies the process versus assembling individual fire control group parts.
- ✅ Built from durable materials with precise machining intended for reliable, long-term function.
- ✅ Three-position selector offers clear, defined modes including a standard semi-automatic setting.
- ✅ Manufactured in the United States with a focus on component quality and fit.
Cons:
- ❌ Higher price point compared to standard semi-automatic triggers. This is due to the complex mechanism and manufacturing.
- ❌ Requires a specific shooting technique (maintained rearward pressure) to utilize the FRT mode correctly. It will not function like a binary trigger.
- ❌ Legal status is a subject of ongoing discussion and varies by jurisdiction. The buyer is responsible for knowing their local and federal laws.
Who Should Buy the FRT-15L3 Trigger?
Buy it if: You are an experienced shooter familiar with AR-15 platforms, understand the mechanical function of a forced reset trigger, and are seeking that specific type of operation for your rifle. You should also be in a jurisdiction where such components are permitted and you accept responsibility for compliance.
Skip it if: You are looking for a traditional semi-automatic trigger pull upgrade, a binary trigger, or your first aftermarket trigger. If you are unsure of the legalities in your area, or prefer a simpler, more conventional trigger system, consider our selection of standard and enhanced AR-15 triggers.
Frequently Asked Questions
What is an FRT trigger?
An FRT, or Forced Reset Trigger, is a fire control group that uses energy from the firearm’s operating system (like gas from a direct impingement AR-15) to physically push the trigger forward to its reset position after a shot is fired. This occurs while the shooter maintains rearward pressure on the trigger. It is mechanically distinct from both standard semi-automatic and binary triggers.
Are FRT triggers legal?
The legal status of forced reset triggers is complex and has been the subject of regulatory and judicial review. As of March 2026, their status can vary based on federal interpretation and state law. It is the sole responsibility of the purchaser to determine the legality of this item in their specific jurisdiction before ordering. Glockswitchstore cannot provide legal advice.
Is the FRT-15 trigger legal?
This question refers to the specific FRT-15 model. The FRT-15L3 is a different iteration. The legality of any forced reset trigger component depends entirely on current federal regulations from the ATF and the laws of your state and locality. You must conduct your own research or consult with a legal professional familiar with firearms law in your area to make this determination.
How to install FRT 15 trigger?
The FRT-15L3 installs as a drop-in cassette unit. Clear and safe your rifle. Push out the existing fire control group pins. Remove the old trigger, hammer, and springs. Insert the FRT-15L3 cassette into the lower receiver’s fire control group pocket. Align the holes and insert the provided pins. Function check thoroughly with the firearm clear and in a safe direction before use.
How to prevent fries from sticking?
This appears to be a common typo or mis-query. If you are asking about preventing the trigger from “freezing” or sticking during the FRT cycle, ensure your rifle is properly lubricated and that the trigger group is clean. The forced reset function relies on specific mechanical timing and gas system pressure; an under-gassed or dirty rifle may not provide sufficient energy for consistent reset.

You can purchase the FRT-15L3 Trigger (Safe/Semi/FRT) directly from Glockswitchstore at glockswitchstore.com. We are a Boise, ID-based retailer that stocks this item and ships quickly and discreetly to customers within the United States where permitted.
Does the FRT-15L3 work with all AR-15s?
