The Horizon Firearms Venatic Carbon 2 in .300 Win Mag, the .300 Winchester Magnum chambering, is a lightweight bolt-action hunting rifle with a 22-inch Proof Research carbon fiber barrel (Horizon part no. HRF-VCA-300W-22R). It pairs the polished Stiller Wombat action with an iota EKO carbon stock, and the 2026 upgrades add a Horizon ARCA plus Picatinny rail plate, a flush-fit magazine and a TriggerTech Rough Diamond trigger. The magnum chambering uses a proprietary 3-round flush magazine, and the 5/8-24 muzzle is ready for a brake or suppressor. Horizon Firearms builds it for hunters who carry in steep country and still want long-range accuracy.

Key Specifications

• The stock is an iota EKO carbon stock, a lightweight design that keeps the rifle easy to carry.

• Capacity is a 3-round flush magazine, the proprietary magnum magazine that sits flush with the bottom metal.
