The matching forend, likewise crafted from gloss-finished walnut, incorporates sharp, well-cut checkering that adds a traditional touch while ensuring a confident, secure grip during extended shooting sessions. Up front, the 34-inch ported barrel is paired with an adjustable ventilated rib and utilizes an interchangeable Improved Modified choke tube, providing adaptability across varying trap disciplines and distances. Completing the setup, a white front bead paired with a silver mid-bead promotes proper sight picture and intuitive target acquisition, reinforcing the model’s reputation as both a visually striking and performance-driven trap gun.
