Double Bell TTI M4 (058M+) with Pre-Installed Wolverine INFERNO Gen 2 Engine & FCU Battery (I)

Product Overview

The Double Bell TTI M4 (058M+) is a competition-style M4 that comes assembled as an HPA rifle. It has a full metal receiver set, an extended modular handguard and a custom ergonomic grip.

A 1-4x20 variable scope and scope mount are included, so you can switch between 1x for close quarters and 4x for longer shots.

The pre-installed Wolverine INFERNO Gen 2 is a single-solenoid HPA engine with independent nozzle movement, so the nozzle is positioned before each shot. It is controlled by the Spartan Board FCU, which lets you set dwell, rate of fire and burst modes through the trigger, with no external programming unit needed. An FCU battery is included; you supply the HPA air line and regulator.
