Redmantoys features a demonstration and performance test of a WE M4CQB airsoft gas blowback rifle. The owner of the shop begins by preparing the full-metal toy gun, loading the magazine with BBs and gas, and explaining the handling procedures. He emphasizes safety protocols, such as keeping the finger off the trigger and pointing the muzzle in a safe direction before starting the functional checks.

During the testing phase, he conducts several shots in semi-automatic mode to measure the feet per second (FPS) consistency. The results show the rifle firing in the range of 460 to 480 FPS, which is noted as a standard performance level for this model. He then transitions to testing the full-auto and burst modes, observing the rapid cycle of the bolt and the mechanical feedback of the blowback system.

The demonstration concludes with a discussion on the mechanical features of the version 2 design, specifically the bolt catch functionality. He mentions that while the open-bolt lock works, he suggests disabling it to prevent wear on certain parts. He also demonstrates a dry-firing method before confirming the unit is ready for the customer and ending the session.
