Unified Performance

Recognizing a lack of options for shotgun owners desiring upgrades that deliver a level of sophistication while also enhancing performance WOOX introduces the GLADIATORE Grip and Forend Kit.

Upgrade your Mossberg® Shockwave or Remington 870 & Tac14 12 GA pump shotgun with Italian designed and manufactured components made of Claro American Walnut. The M-LOK® rails on the fore end at the 3 o'clock and 9 o'clock positions add versatility while aggressive checkering on both provide exceptional grip. The Club Grip is a simple single screw installation while the Forend includes a handy wrench to make installation a breeze.

Hand-finished in Hickory, NC. Precision-machined in Italy. Every piece individually selected from our Claro Walnut harvest since 1937.

faqS 

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.
