The FRT 15 Rare Breed Trigger is a forced reset trigger designed for AR-15 platforms. It’s for shooters who want a specific, rapid-fire function from their rifle. Since we started stocking it in mid-2024, it’s become a steady seller in our trigger category. One note from our staff: a customer returned it for being ‘too tight,’ which turned out to be due to an aftermarket lower receiver frame. It works as intended with OEM parts.
Stand-Out Features
- Forced reset mechanism for rapid, controlled fire.
- Constructed from heat-treated 4140 steel and 7075-T6 aluminum for durability.
- Designed for drop-in installation in mil-spec AR-15 lower receivers.
- Maintains a semi-automatic function per the manufacturer’s design intent.
- Includes all necessary pins and springs for installation.

Your Questions Answered
Is this legal to own?
As of our last update, this trigger is a legal firearm component for individuals who can legally possess firearms. However, laws vary by state and locality. It is the buyer’s responsibility to know and comply with all federal, state, and local laws before purchasing. Polymer80Warehouse is a licensed FFL and ships only to valid FFL holders for transfer.
Will this work in my Polymer80 lower?
We strongly recommend using this trigger in an OEM (Original Equipment Manufacturer) mil-spec AR-15 lower receiver. We had a customer report a fitment issue that was traced to an aftermarket frame. For reliable function and to avoid potential fitment problems, use with standard, in-spec lowers.
What is your return policy?
We offer a 30-day return period for unused items in original packaging. If you have a function issue, please contact us first. As noted, fitment can vary with non-OEM parts, so ensure compatibility. Returns are processed through our Cape Girardeau warehouse.
