At WOOX, a rifle stock begins with material and purpose. The walnut, the structural core, the aluminum, and the geometry all matter because the stock is the part of the rifle the shooter touches, carries, supports, and returns to after every shot.
Every platform WOOX makes is rooted in the Minelli family’s workshop tradition since 1937. The work is not rushed, and the material is not treated as decoration. American Walnut is selected for figure, density, and structural integrity before it becomes part of a rifle stock built to be used for years, not seasons.
Below is a fact-based comparison between two distinct WOOX approaches:
- WOOX Furiosa Ultra, a competition-oriented chassis system
- WOOX Superleggera, a lightweight field stock
Each is built for a different rifle life.
Purpose and Platform Philosophy
Furiosa Ultra
Furiosa Ultra is a purpose-built chassis platform for positional and long-range shooting. It extends the original Furiosa design with features requested by PRS shooters: repeatable adjustability, balance tuning, and accessory support.
Furiosa Ultra is built for PRS/NRL-style positional and long-range shooting, with a full-length Arca rail, 10-inch M-LOK mounting areas, and the WOOX Suspense™ weight system for balance adjustment.
Superleggera
Superleggera is built for movement. It combines American Walnut with a carbon-reinforced nylon mini-chassis and is listed by WOOX as a drop-in stock that does not require pillars or extra bedding.
Its purpose is different from Furiosa Ultra. Superleggera emphasizes lower carry weight, field handling, and useful fit adjustment without turning the rifle into a competition chassis.
Construction and Materials
Furiosa Ultra
Furiosa Ultra uses an AA 7075 aircraft-grade aluminum, hard-anodized chassis with American Walnut. WOOX lists drop-in installation, no pillars, no extra bedding, and no gunsmithing required for compatible configurations.
Key construction details include:
- AA 7075 hard-anodized aluminum chassis
- American Walnut
- Full-length Arca rail
- Dual 10-inch M-LOK mounting areas
- WOOX Suspense™ weight system
- Micro-adjustable cheek riser
- Adjustable length of pull
- 2-way adjustable butt pad, with vertical adjustment and left/right rotation
- Bag-rider rear profile
The Suspense™ system allows up to six 2.5-ounce weights in the fore-end. Two weights are included, and additional weights are sold separately.
Superleggera
Superleggera uses American Walnut with a carbon-reinforced nylon mini-chassis. WOOX lists a V-Block Bedding Mini Chassis in carbon nylon, drop-in installation, an adjustable cheek riser, and a vertically adjustable recoil pad.
Key construction details include:
- American Walnut
- Carbon-reinforced nylon mini-chassis
- V-Block Bedding Mini Chassis
- Drop-in installation
- Adjustable cheek riser
- 1-way vertically adjustable recoil pad
- Lower overall weight than Furiosa Ultra
Superleggera is the lighter, simpler platform. It is built for a rifle carried in the field, not a rifle built around rails, weights, barricades, and support gear.

Adjustability and Ergonomics
Furiosa Ultra
The Ultra chassis provides a wider range of ergonomic adjustment:
- Micro-adjustable cheek riser
- Adjustable length of pull with spacers
- 2-way adjustable butt pad
- Full-length Arca rail
- M-LOK mounting areas
- Suspense™ weight tuning
- Rear bag-rider profile
These features serve shooters in positional and scoring environments where rifle balance, support placement, and repeatable body position matter.
Furiosa Ultra does not make the rifle accurate by itself. A rifle is a system. Barrel, ammunition, optic, installation, shooter input, and conditions all matter. Furiosa Ultra improves the part WOOX controls: the chassis, the contact points, and the accessory interface.
Superleggera
Superleggera keeps adjustment simpler:
- Adjustable cheek riser
- Vertically adjustable recoil pad
- Lighter overall build
- Field-focused stock geometry
- Carbon-reinforced nylon mini-chassis with American Walnut exterior
The purpose is not to create a PRS chassis. Superleggera is built for the rifle owner who wants lower carry weight, clean handling, and a simpler hunting-stock setup.
Practical Performance Context
Furiosa Ultra gives the shooter a more adjustable, accessory-ready platform. Its hard-anodized AA 7075 aluminum chassis, Arca rail, M-LOK mounting areas, and Suspense™ weight system make it the stronger fit for rifles used from bipods, bags, barricades, and match positions.
Superleggera prioritizes field movement. Its 2.2–2.6 lb listed weight, American Walnut exterior, and carbon-reinforced nylon mini-chassis make it the lighter option for hunting and general field use. WOOX notes that weight can vary because of natural wood density and compatible rifle model differences.
Group size and point of impact should not be treated as guaranteed outcomes from either stock. Accuracy depends on the entire rifle system: action, barrel, ammunition, optic, torque, installation, shooter input, and conditions.
Which Platform Matches Your Purpose?
Precision and Competition
Choose Furiosa Ultra if your priority is positional control, balance tuning, and accessory support.
It is the stronger fit when the rifle will be used with:
- Bipods
- Bags
- Barricades
- Arca clamps
- M-LOK accessories
- Weight tuning
- PRS/NRL-style positional and long-range shooting
Furiosa Ultra is the more technical stock. It is built for the shooter who wants a rifle configured around repeatable support and adjustability.
Hunting and Mobility
Choose Superleggera if your priority is lower weight, natural carry, and a simpler field setup.
It is the stronger fit when the rifle will be used for:
- Hunting
- Long carries
- Field shooting
- Mountain or hill-country movement
- General-purpose bolt-action builds
- Shooters who want walnut without unnecessary hardware
Superleggera is the more field-focused stock. It keeps the system lighter and less hardware-heavy while preserving the WOOX material character.
Craft and Legacy
Both Furiosa Ultra and Superleggera share the same WOOX standard: American Walnut selected for the rifle, not applied as decoration.
Furiosa Ultra joins walnut to a hard-anodized AA 7075 aluminum chassis. Superleggera joins walnut to a carbon-reinforced nylon mini-chassis. Those material choices define the difference between the two stocks.
One is built for competition control. The other is built for field weight.
Choose Furiosa Ultra when the rifle’s life is stages, bags, rails, and balance tuning. Choose Superleggera when the rifle’s life is long carries, clean handling, and a lighter field profile.
A WOOX stock is not chosen because it is the most convenient replacement. It is chosen because the rifle is worth building correctly.
FAQs
What is the main difference between Furiosa Ultra and Superleggera?
Furiosa Ultra is a competition-focused wood-and-aluminum chassis with Arca, M-LOK, adjustable geometry, and the Suspense™ weight system. Superleggera is a lighter field stock with American Walnut, a carbon-reinforced nylon mini-chassis, and simpler fit adjustments.
Which is best for long-range or PRS/NRL?
Furiosa Ultra is the stronger fit for PRS/NRL-style positional and long-range shooting because it supports repeatable positioning, balance tuning, Arca accessories, M-LOK accessories, and a more adjustable rifle setup.
Which is better for hunting?
Superleggera is the stronger fit for hunting and field carry because it is lighter and simpler. WOOX lists its weight at 2.2–2.6 lb, with variation depending on wood density and compatible rifle model.
Which has more adjustments?
Furiosa Ultra has more adjustment. It includes a micro-adjustable cheek riser, adjustable length of pull, 2-way adjustable butt pad, full-length Arca rail, M-LOK mounting areas, and the Suspense™ weight system. Superleggera keeps adjustment simpler with cheek-riser and vertical recoil-pad adjustment.
Does Furiosa Ultra weigh more than Superleggera?
Yes. Furiosa Ultra is the heavier competition platform, while Superleggera is the lighter field stock. WOOX lists Superleggera at 2.2–2.6 lb. Furiosa Ultra weight varies by configuration, and WOOX lists 5.2–5.7 lb in its detailed specification table.
Are they accurate over time?
A stock does not guarantee accuracy by itself. Both stocks are built to give the rifle a more structured interface, but group size and point of impact depend on the rifle, barrel, ammunition, optic, installation, shooter input, and conditions.
