An upgrade kit is simply an HPA engine without the solenoid. This saves you money by allowing you to move the solenoid from one engine to the other.

It is a hybrid design which keeps the advantages of an open bolt system: easy tuning, no first round dry fire, efficiency, etc… and adds the simplicity of easier hop up tuning that closed bolt systems have traditionally offered.

The MTW is designed to be a modular platform with highly interchangeable parts within the MTW-Spec family, with real steel firearms, and with AEGs when possible.

The XTS fine-tunes every stage of the shot cycle. Its “extended stroke” system improves hop-up air seal, enhances feeding forgiveness, and increases separation between loading and firing movements to help stabilize each BB for tighter groupings and more consistent shots. A newly engineered valve housing optimizes internal airflow, reduces air waste, and improves dwell tuning tolerance—making precise tuning more accessible in a wider range of setups. The new recoil out port is compatible with the QUAKE MTW Recoil Stock for enhanced realism. (MTW Only)

When referring to HPA airsoft guns, the centering of the nozzle, hop, and inner barrel to create a straight path for the BB. In AEG conversions, aligning can mean using shims to make small adjustments to the engine placement within the gearbox. The MTW has “Intrinsic Alignment,” meaning the upper receiver is machined precisely to hold an HPA engine with no room for movement.

The MTW Billet Series is CNC machined from solid blocks of aluminum, while the Forged Series is machined from real AR forgings. These two methods create two distinct styles of receivers, however the functional components and performance are the same.
