FRT® comparison
Flat vs. curved trigger shoe: which should you choose?
Your Rare Breed FRT® comes with a flat or curved trigger shoe — the face your finger presses. It won’t change how fast the trigger resets, but it does change how the pull feels. Here’s how to pick.
A curved trigger shoe follows the natural arc of your finger and indexes the same way every time. A flat trigger shoe gives a straighter finger position with a bit more leverage and a consistent contact point. Both deliver the exact same forced reset performance — the shoe only changes feel and ergonomics, not function.
When you choose a Rare Breed FRT-15® you make two separate decisions: single-stage or two-stage, and flat or curved shoe. This guide covers the second one.
What the trigger shoe actually changes
The “shoe” is the flat or curved blade your finger rests on. It doesn’t touch the FRT® mechanism at all — the reset, the modes, and the speed are identical between flat and curved. What changes is ergonomics: where your finger sits, how the pull feels, and how consistently you contact the trigger from shot to shot. It comes down to personal preference, and plenty of shooters own both over time.
Curved shoe
The classic feelA traditional curved blade that cradles your fingertip.
- Feels: natural, familiar, instinctive
- Best for: shooters who like a traditional AR feel and consistent finger placement
- Why pick it: the curve self-indexes your finger to the same spot
Flat shoe
Straight & modernA flat face that sits straighter under your finger.
- Feels: straight, with a bit more leverage
- Best for: shooters who want a lower, more consistent contact point
- Why pick it: the flat face can make the break feel lighter and more repeatable
Flat vs. curved at a glance
| Curved | Flat | |
|---|---|---|
| Finger position | Follows your finger’s arc | Straighter, lower contact point |
| Feel | Traditional & familiar | A touch more leverage |
| Self-indexing | Yes — curve guides your finger | You set your own contact point |
| Forced reset performance | Identical | Identical |
| It’s really about | Comfort & familiarity | Leverage & consistency |
Same trigger. Same speed. Just a different face under your finger.
Which shoe should you buy?
There’s no wrong answer — only what feels best to you. A quick guide:
- Choose curved if you’re used to a standard AR trigger, want a familiar feel, or like the way a curve guides your finger to the same spot every time.
- Choose flat if you prefer a straighter finger position, want a little extra leverage, or like setting a lower, consistent contact point.
- If you can, try both. Many shooters find they prefer one only after feeling the other. If you’re new to forced reset triggers, the curved FRT-15L3® is the most familiar starting point.
Don’t forget the other choice: stage
Shoe shape is only half the decision. You’ll also choose single-stage (the FRT-15L3®) or two-stage (the FRT-15C3®), and both come in flat and curved. We break that down in single-stage vs. two-stage FRT. Put the two choices together and you can match a Rare Breed FRT exactly to the way you shoot.
Whichever you choose, it’s the genuine Rare Breed FRT®
