Pheas Airsoft got a step-by-step guide for disassembling the Double Eagle M931A DRP9 Airsoft rifle for maintenance and repairs. The process begins with the upper section, where the presenter shows how to remove the entire stock assembly by taking out the back body pin and the quick-change spring screw. Following this, the guide demonstrates how to detach the barrel and hop-up unit after pushing out the front body pin, preparing the main body for access to the lower components.

Next, the video focuses on the lower receiver, detailing the removal of several critical parts. This includes carefully taking out the spring-loaded bolt release assembly, disconnecting the motor and wiring from the pistol grip, and removing the selector switches. These steps are crucial as the selector switches and pins secure the gearbox within the lower receiver, making their removal necessary before proceeding to the heart of the airsoft gun.

The final and most detailed section of the guide covers the gearbox itself. Pheas Airsoft shows how to safely open the gearbox shell, inspect components like the gears and optical MOSFET system, and check the air seal. From there, he reverses the process, providing careful instructions on reassembling the gearbox, including the proper placement of the anti-reversal latch, before finishing the overall reassembly of the DRP9.
