Another helpful video from Pheas Airsoft for owners of the Army Armament R907 Raptor. The video begins with the removal of external components, including the muzzle brake, sights, and handguard. Pheas Airsoft demonstrates how to split the receiver and remove the barrel assembly by engaging a release button, though he admits to a brief "smooth brain" moment while remembering exactly how the mechanism jiggles apart. He also points out a humorous labeling error on the hop-up unit, where the "up" and "down" directions for adjustment are actually reversed.

Moving to the internals, the process involves extracting the version 3 gearbox and the motor. A feature identified is the quick-change spring system, which allows for easy power adjustments without a full teardown. He encounters some oily components and soldered motor wires, which he notes can make maintenance a bit of a sticky situation. He also discovers a simple MOSFET system, though its specific features remain a bit of a mystery.

The final segment focuses on opening the gearbox to inspect the piston, gears, and bearings. Reassembly proves to be the true test of patience, involving a struggle with a runaway shim and the classic "swearing-inducing" task of lining up the trigger and gears. Despite a few "clumsy" moments and a distracting roof leak mid-filming, the guide ends with the rifle successfully put back together, ready for its next game day.
