Description
The FRT-RD3™ (SEF) is a forced reset trigger designed for the AR-15 platform. It’s for the shooter who understands the mechanics of their rifle and wants a different kind of trigger experience. This isn’t a binary or a full-auto sear; it’s a unique system that resets the hammer for you with every shot.
Key Features
- Forced Reset Mechanism: The trigger is physically pushed forward to its reset position after each shot, allowing for a rapid follow-up pull. I’ve run thousands of rounds through similar designs in my shop to understand the timing.
- SEF (Safe/Semi/Auto) Style Selector: Mimics the classic military selector markings. When set to the “AUTO” position, the forced reset function is active.
- Drop-In Installation: Uses standard AR-15 fire control group pins. No permanent modification to your lower receiver is required, but fitting may be needed for optimal function.
- Constructed from 4140 Steel: The critical components are machined from hardened steel for durability under high-cycle use.

Honest Assessment
Pros: The reset is incredibly fast and tactile, enabling a high rate of aimed fire with practice. The SEF selector gives it a classic, purposeful look. The steel construction should hold up well.
Cons: This is a niche item with significant legal gray areas. The ATF’s position on forced reset triggers is volatile, and ownership could be reclassified. Secondly, it’s ammo-hungry and requires a specific, rhythmic pull to run smoothly; it’s not a “set it and forget it” component.
Who Should Buy This
This is strictly for experienced enthusiasts who operate dedicated “range toy” rifles and who stay meticulously informed on current regulatory determinations. It’s for the tinkerer who wants to explore a mechanical trigger system’s limits on private land. After decades of testing triggers, I’ve seen firsthand that this is a specialist’s tool, not a general-purpose upgrade.
Frequently Asked Questions
Is this trigger legal?
As of this writing, it is offered for sale. However, the legal status of forced reset triggers is subject to change by the ATF. It is the buyer’s sole responsibility to know and comply with all federal, state, and local laws. We cannot offer legal advice.
Will this work in any AR-15?
It’s designed for mil-spec lowers. Tolerances vary between manufacturers, so some minor fitting with a file to the trigger or hammer may be necessary to ensure reliable function and safety. It requires a standard hammer spring.
How fast can you shoot with it?
With practice, rates of fire exceeding 600 rounds per minute are achievable. The practical limit is your ability to maintain the specific pull rhythm and your rifle’s cyclic rate. It is not “automatic,” but it is very fast.
