Real-World Use Cases
Perfect for close-quarters battle (CQB) skirmishers, this TTI MPX-K excels indoors and in milsim scenarios where manoeuvrability matters. Its compact profile and Picatinny rail interface allow you to build a ‘recce gun’ with minimal weight, or run it bare for pump-action drills. The V2 gearbox is popular among UK technicians, meaning parts and service support is readily available.
