DESIGNED FOR COMPETITION, BUILT TO WIN

furiosa-ultra-14.jpg__PID:91a98cdc-7b0a-4fd8-ae35-2a2e46a16d1a

Proudly Made in Italy and assembled in Hickory, NC

Furiosa Ultra is the answer to requests from PRS shooters wanting the ultimate classical wood stock and chassis system from WOOX.

A full 3” longer than the flagship Furiosa, Furiosa Ultra widens the barrel channel to accommodate barrels up to 1.20” in diameter, adds a full-length Arca rail, and incorporates the WOOX Suspense™ weight system.

Integrated into the fore end of the Furiosa Ultra, the Suspense System allows for up to six 2.5-ounce weights to be arranged to achieve proper balance. Two weights are included (additional weights sold separately).

The vented fore end includes port and starboard M-LOK™ panels for maximizing accessorizing capability.

The striking shoulder stock of the Furiosa has been remodeled in the Furiosa Ultra for competition with a vertical grip and matching bag rider. Thumb rests are molded into the chassis, milled from aircraft-grade aluminum. Micro-adjustable cheek riser and LOP, microcell 2-way adjustable butt pad and a 3.5" bag rider create custom fit and stable platform delivering exceptional accuracy.

WILL THIS FIT MY RIFLE?

RARE BY NATURE. HANDMADE BY CHOICE.

Every WOOX stock is one of one—cut from American walnut whose grain, figure, and density can’t be replicated. We don’t mold, we select—then shape and finish each piece by hand, the same way our family has worked since 1937.

That choice sets a hard limit: out of every harvest, only a small fraction meets our standard for figure, density, and structural integrity—roughly 1 in 25 blanks. From there, each piece is individually selected and hand-finished by our craftsmen.

You’re not just upgrading a rifle; you’re securing a piece that won’t exist again in the same form—made to be carried, used, and kept for a lifetime. This isn’t mass production. It’s selection, restraint, and time—resulting in a rifle you won’t see twice and won’t need to replace.
