B3 Archery Flo X Thumb Release — The World's Most Dynamic Thumb-Activated Release
The B3 Archery Flo X is B3's flagship thumb-button release, and it earns that title. Loaded with features that most thumb releases charge extra for — or simply don't offer — the Flo X combines micro-adjustable travel and tension, a customizable handle with 3 movable finger positions, hardened and polished stainless-steel hook and internals, a gated hook for easy loading, and a Cerakote finish that holds up in the field. It runs as a 3-finger or 4-finger release, giving you the flexibility to shoot it however your hand prefers. If you've been looking for a thumb release that truly adapts to your hand and shooting style rather than the other way around, the Flo X is the answer.
Key Features of the B3 Flo X Thumb Release
3 Movable Handle Positions
The Flo X's handle has 3 movable finger location positions, allowing you to physically reshape the grip geometry to match your hand. Most thumb releases give you one handle shape and that's it — the Flo X lets you move the contact points to where your fingers actually want to sit.
Micro-Adjustable Travel and Tension
Both trigger travel and tension are independently micro-adjustable. Dial the travel down for a hair-trigger feel or open it up for more deliberate control. Adjust tension from feather-light to heavy without swapping springs. Two screws, infinite combinations.
Hardened and Polished Stainless-Steel Hook and Internals
The Flo X uses hardened, polished stainless-steel throughout the hook and internal sear system for long-term durability and a consistent, crisp break. These aren't soft metal components that wear in over thousands of shots — they're built to perform exactly the same way years down the road.
Gated Hook for Easy Loading
The retainment gate allows you to load the D-loop without pushing down a cocking button or forcing the hook open manually. It's faster, quieter, and one less thing to think about when a deer walks in.
3-Finger or 4-Finger Configuration
The Flo X can be run in either a 3-finger or 4-finger configuration, giving you the option to find the grip that provides the most natural, repeatable hand position for your shot.
Cerakote Finish
Durable Cerakote coating protects the handle from the corrosion, moisture, and impact that come with regular hunting and range use.

- Serious archers and bowhunters who want a top-tier thumb release with genuine customization
- Shooters who have struggled to find a thumb release that fits their hand correctly
- Archers transitioning from a wrist strap to a handheld thumb button

Why Extreme Outfitters Recommends the Flo X
The Flo X is the thumb release we point serious archers toward when they're ready to stop settling. The combination of movable handle positions, independent travel and tension adjustment, and a gated hook in a single release is genuinely rare at any price point.

If you're investing in a thumb button that's going to stay in your rotation for years, the Flo X earns it.
