Let’s talk straight about the Rare Breed FRT-15. This isn’t a standard trigger pack. It’s a mechanically distinct, forced-reset system that changes the functional operation of your AR-15. We’re offering it here for educational and informational purposes to enthusiasts who understand the mechanics of their platform. It is the buyer’s sole responsibility to know and comply with all federal, state, and local laws. This product’s status can change; you need to do your homework before purchasing.

We stock it because it’s a piece of interesting engineering. The guys at Rare Breed designed a trigger that uses the rifle’s own recoil impulse to do the work. When the bolt carrier group goes back into battery, it physically pushes the trigger forward to the reset position. This mechanical action is what defines a “forced reset.” The result is a shooting cycle limited primarily by your bolt’s cyclic rate and your ability to maintain forward pressure on the trigger. It requires a specific technique—a constant, steady push—rather than a traditional pull, release, and reset.

What’s In The Box & Build Quality

You get a complete kit. The trigger group itself, a three-position safety selector (Safe, Semi, Forced Reset), and a set of anti-walk pins. Don’t toss those pins; use them. This unit sees different forces than a mil-spec trigger.

The construction is serious. The housing is 7075-T6 aluminum, the same stuff used for upper and lower receivers. Internal components are wire-EDM cut for precision and treated with a black nitride QPQ finish. This isn’t a MIM part kit. It’s machined, it’s tough, and it’s built to handle the stress. The feel is crisp, with a distinct break and that immediate, positive reset.

Installation & Function: Pay Attention

Installation is like any other drop-in trigger, but the details matter. Ensure your rifle is CLEAR. Follow the included instructions to the letter. The orientation of the safety selector is crucial for the three-position function to work correctly. Once installed, you must perform a full function check without ammunition. You should feel three distinct detents on the selector: Safe, a standard semi-auto mode, and the third position for the forced-reset function. The trigger will not behave like you’re used to in that third mode. It will not reset unless the bolt cycles. This is normal. If anything feels off, stop. Do not force it. Consult a competent gunsmith familiar with the system.

Maintenance: Keep it clean and lightly lubricated. Carbon buildup can affect the reset mechanism. Periodically check the tightness of the anti-walk pins.

Compatibility & Considerations

The FRT-15 E3 is designed for the standard AR-15/M16 platform. It works with mil-spec and commercial lower receivers. Performance can be influenced by your specific setup—buffer weight, spring, gas system. A properly gassed rifle will run it more consistently. We do not recommend this for beginners. You need a firm understanding of your firearm’s operation and safety protocols. This is a specialized component for experienced shooters.

Frequently Asked Questions

Is this a “machine gun” or an auto-sear?

No. It is a mechanically different trigger system that uses a forced-reset action. It fires one round per function of the trigger. The rate of fire is dependent on the shooter maintaining forward pressure and the cyclic rate of the bolt.

Is it legal for me to own?

We cannot give legal advice. The regulatory status of this item is subject to change and varies by jurisdiction. You, the purchaser, are 100% responsible for determining the legality in your city, county, and state before ordering. We will not process orders to locations where it is prohibited.

What’s the difference between this and a binary trigger?

Completely different mechanics. A binary fires one round on pull and one on release. The FRT fires on pull and resets via bolt force, requiring constant forward pressure to fire again. The technique and feel are not the same.

Does it work with .22 LR conversions?

Generally, no. The system relies on the full recoil impulse of a centerfire 5.56/.223 bolt carrier group to actuate the reset. A .22 LR bolt does not generate enough force.

What is your return policy on this item?

Due to the nature of this product, all sales are final once the package leaves our facility. Ensure you have done your legal and compatibility research prior to purchase.

Bottom Line from the Shop: The Rare Breed FRT-15 E3 is a niche, well-made piece of engineering for the experienced AR-15 owner who understands the mechanism and the legal landscape. It offers a unique shooting dynamic. It is not a magic button; it requires practice and a specific technique. Know your laws, know your rifle, and if you proceed, install it correctly and safely.
