The Griffin Armament Mk2 Woox & Proof Upgraded Rifle

Overview of the Griffin Armament Mk2 Collaboration Build

The hosts introduce a special collaboration rifle built from components provided by three companies: Griffin Armament, Proof Research, and Woox. The rifle is based on an AR-15 platform but stands out with its distinctive wood furniture from Woox. They emphasize that every major component on the gun is unique to this build. The video is framed as a detailed walk-through of how these parts come together, focusing on the receiver set from Griffin Armament, the carbon fiber–wrapped barrel from Proof Research, and the Woox walnut chassis. The hosts note that the rifle looks visually striking and different from a typical AR-15, setting the stage for a closer look at each element.

Griffin Armament Mk2 Receiver Set and Ambidextrous Controls

Attention turns to the Griffin Armament Mk2 upper and lower. Griffin Armament is described as a company known for complete rifles and suppressor lines. The Mk2 receiver set is fully ambidextrous, allowing left- or right-handed shooters to manipulate the bolt and controls using their primary firing hand. The hosts discuss ambidextrous safety selectors, bolt hold-open, and bolt release functions, noting how convenient it is to run the rifle using the trigger finger for these tasks. They mention that the Mk2 lower resembles designs from ADM, explaining that Griffin Armament and ADM previously worked together, which is why the lower looks similar. Internal components such as the Griffin charging handle and bolt carrier group are highlighted as part of a cohesive Griffin Armament package.

Proof Research Carbon Fiber Barrel and Caliber Details

The barrel from Proof Research is presented as a standout component. It is a steel barrel wrapped in carbon fiber, offering significant weight savings while maintaining strength. The hosts state that this specific Proof Research barrel alone costs around a thousand dollars and comes with a sub-MOA accuracy guarantee. The barrel is chambered to handle both .223 Wylde and 5.56, giving flexibility while maintaining reliable and accurate performance. They note that the barrel length is 16 inches with a mid-length gas system and a 1:8 twist rate, which supports intermediate-distance shooting with good stabilization. The combination of light weight, sub-MOA potential, and dual-caliber capability is emphasized as a key performance feature of the build.

Muzzle Device, Suppressor Mount, and SPR Role

The rifle is equipped with a Griffin Armament muzzle device that serves as a mount for the company’s Dual-Lok suppressor system. The hosts explain that this setup allows the user to attach a Griffin Armament suppressor directly, though the muzzle device can be swapped if a different suppressor system is preferred. They describe the rifle’s intended role as an SPR or DMR-style setup, built around the 16-inch mid-length gas barrel and precision-oriented components. A Harris bipod is mounted to support stable shooting from supported positions, reinforcing the rifle’s focus on accurate, longer-distance engagements. The configuration is presented as optimized for precision use while retaining the versatility of a 5.56/.223 Wylde AR-15.

Woox Walnut Furniture and Chassis Features

The hosts then focus on the Woox Vigilante furniture, describing it as American walnut with detailed craftsmanship. The wood chassis includes recessed M-LOK slots in the handguard, allowing accessories to sit neatly within the walnut. The pistol grip is also walnut, with shaping and texturing that provide a comfortable hold. They point out an indentation near the safety area that ensures clearance for various safety selectors, showing that Woox considered compatibility with different controls. The buttstock features additional M-LOK slots and QD sling points, enabling attachment of risers or other M-LOK accessories. The stock has noticeable weight toward the rear, making it suitable for use with a rear bag or sandbag when shooting from a supported, precision-oriented position.

Handling Impressions and Final Thoughts

Initial skepticism about wood furniture on an AR-15 gives way to appreciation once the rifle is handled in person. The hosts remark that the Woox grip feels good in the hand and that the overall rifle has a distinct, refined appearance. They highlight how the ambidextrous controls on the Griffin Armament Mk2 lower work smoothly, demonstrating how easily the bolt can be locked back or released. The Trijicon AccuPoint optic, mounted in an ADM mount with a 2.5–12x magnification range, is mentioned as complementing the rifle’s precision role. Overall, the build is described as crisp and visually striking, with the hosts suggesting it could serve both as a capable shooter and as a showpiece in a collection.
