Product Overview
The Double Bell TTI M4 058M+ HPA Rifle is a high-performance, custom-configured airsoft platform factory-fitted with the advanced Storm HP-R HPA Engine. Designed for competitive skirmishers and tactical field operators, this system replaces traditional mechanical gearboxes with a solenoid-driven pneumatic drive, providing instantaneous trigger response, exceptional consistency, and adjustable dwell and velocity. The rifle features a precision CNC-machined aluminium receiver and handguard styled under the TTI configuration, complete with an ergonomic stippled custom grip. Outfitted out of the box with an adjustable 1–4x20 illuminated variable optic, this package delivers direct deployment capability for mid-to-long-range engagements.
