The Proof Research Tundra 300 PRC Green Jungle 22" rifle blends long‑range precision with a lightweight hunting profile. Built on the Defiance Ruckus bolt action and paired with a 22" carbon fiber wrapped match‑grade barrel threaded 5/8x24, it delivers repeatable accuracy backed by Proof Research’s sub 1/2 MOA guarantee. The sleek black metalwork contrasts with a rugged Green Jungle carbon fiber stock featuring an adjustable cheek piece for a custom fit.

This Tundra configuration is ideal for hunters and precision shooters who need a rifle that stays light on long hikes yet stable behind the rifle at extended distances. Chambered in 300 PRC with a 1‑in‑9 twist, it is purpose‑built for modern high‑BC projectiles and serious long‑range work at the range or in the field. Free‑floating construction, a TriggerTech trigger, and BDL‑style magazine round out a package that reflects Proof Research’s focus on innovation, craftsmanship, and real‑world performance.
