Not real carbon fiber, the stock was made with 14+ layers of 1/4" (3 ply) plywood glued & clamped till dry. The different layers were pre-cut to follow the shape of the receiver/barrel etc. That way it saved carving out that much from a solid wood blank. After finishing the final shape it was given it's look with the Hydrodip paint film process & sealed with polyurethane. The bottom of the pistol grip has a notched area that clears the magazine when installed or removed. It works smoothly, just push the release & rotate the mag forward like normal (to remove).
