Technical Information

Castello MOD101-TX is a semi-automatic 12-gauge shotgun engineered for superior control and speed. Featuring a fixed stock, adjustable cheek riser, and two integrated emergency shell holders, it delivers rapid access and ergonomic handling in high-pressure situations. Available in 4+1 or 7+1 magazine configurations and with 20″, 24″, or 28″ barrel options, the MOD101-TX adapts to a wide range of use cases—from hunting to tactical applications.
The lightweight, durable aluminum receiver is protected with anodized, Cerakote, or hydro-dip finish options, while the synthetic stock and forearm are built for long-term reliability and comfort. Ambidextrous right and left M-LOK slots allow secure mounting of lights, lasers, and other accessories. A single emergency shell carrier mounted near the chamber provides one-handed access to ammunition when every second counts.
Chambered for 3″ (76 mm) shells and equipped with a modular choke system, the MOD101-TX offers broad ammunition compatibility and shooting flexibility. Reliable, versatile, and thoughtfully configured, it’s an excellent choice for both field and tactical users.
