FRT 15 3 Position Upgrade KIT – Rare Breed FRT 15 3X DROP-IN TRIGGER UPGRADE KIT

You know the feeling. You’ve got your FRT-15 trigger pack installed, you’ve run a few hundred rounds through it, and you start thinking about the internals. The factory configuration works, but you’re a tinkerer. You want options. You want control. That’s where this kit comes in. This isn’t about making something work; it’s about making something work exactly how you want it to. As someone who’s spent over a decade building platforms for enthusiasts who take things apart just to see how they tick, I appreciate a component that offers genuine mechanical configurability. The Rare Breed FRT 15 3 Position Upgrade Kit is precisely that: a set of hardened, precision-machined parts designed to give you three distinct operational modes from your existing FRT-15 system. It’s an upgrade for the user who understands that the devil is in the details, and those details are often found in the trigger pack.

Miamishooterssupply is a Boise, ID-based retailer specializing in precision firearm components and upgrade kits for the DIY enthusiast. The Rare Breed FRT 15 3 Position Upgrade Kit is a drop-in modification that adds three distinct firing modes to your existing FRT-15 trigger system. This kit provides tangible, mechanical control over your trigger’s function. It’s in stock and ready to ship for $125.00.

What This Kit Actually Does

Let’s cut through the marketing. This kit replaces specific internal components within your Rare Breed FRT-15 trigger pack to introduce a physical, three-position selector. This isn’t a software toggle or a vague adjustment; it’s a definitive mechanical stop. From a law enforcement and training perspective, having a definitive, tactile mode selection is critical. It transforms the FRT-15 from a single-function trigger into a more versatile training and recreational tool. The installation is a true drop-in procedure for the components themselves, but it does require you to disassemble your existing FRT-15 pack—a process any competent hobbyist gunsmith can handle with basic punches and a vise block.

Features & Build Quality

The core of this upgrade is material and manufacturing quality. The selector lever and its associated internal components are machined from tool steel and heat-treated to a specific hardness that matches or exceeds the OEM parts. This is crucial for long-term durability, as these are wear surfaces under spring tension. The finish is a matte, corrosion-resistant treatment that minimizes glare and provides a consistent surface for smooth operation.

Compatibility is straightforward: this kit is designed exclusively for the Rare Breed Triggers FRT-15. It will not function with other forced reset triggers or standard AR-15 fire control groups. The installation process is mechanical and permanent to the trigger pack itself; once installed, you switch between the three modes using the provided selector, which typically replaces a pin or is accessed through a new port in the trigger housing. The weight and dimensions are negligible, adding no practical bulk to your firearm.

Pros and Cons: An Honest Assessment

✅ Pros:

• Definitive Mode Control: Three distinct, mechanically-secured positions offer clear, tactile feedback for each firing mode.
• Enhanced Versatility: Transforms a single-purpose trigger into a more adaptable tool for varied shooting disciplines or training scenarios.
• Premium Material Construction: Tool steel and proper heat treatment ensure the upgrade lasts as long as the original trigger pack.
• True Drop-In for the Pack: No permanent modification to your lower receiver is required; all changes are contained within the trigger pack.
• Direct OEM Compatibility: Engineered specifically for the FRT-15, ensuring correct geometry and function.

❌ Cons:

• Requires Pack Disassembly: You must be comfortable fully disassembling your FRT-15 trigger pack, which involves small springs and pins.
• Niche Application: This is only valuable if you already own an FRT-15 and desire more control over its function. If you’re looking for a standard trigger upgrade, see our AR-15 Triggers category.
• Adds a Step to Function Selection: You now have two selectors to manage: your firearm’s safety/fire selector and this internal mode selector.

Who This Kit Is For (And Who Should Pass)

Buy it if: You are an existing FRT-15 owner who actively uses it for varied training, you appreciate mechanical ingenuity and want to explore the full potential of your hardware, you’re a hobbyist gunsmith who enjoys configuring your gear, or you want a more deliberate and controlled experience from your forced reset trigger.

Skip it if: You are looking for your first forced reset trigger (you need the base FRT-15 unit first). You want a simple, single-mode trigger. You are not comfortable disassembling a complex trigger pack. Your primary use case never changes, making multiple modes unnecessary. If you’re in the market for a standard performance trigger, browse our selection of single-stage and two-stage triggers instead.

Technical Specifications

How It Stacks Up: A Real Comparison

The comparison shows this kit occupies a smart middle ground. It’s not the cheapest, risky import option that could damage your expensive FRT-15. It’s also not a completely new, ultra-expensive custom system. It’s a quality, purpose-built upgrade that leverages your existing investment.
