This residue attracts dust, dirt, and other particulate matter, forming an abrasive layer within the airsoft gun’s internal mechanisms. This buildup impedes smooth operation, accelerates wear, and compromises performance. An example includes applying WD-40 to an AEG gearbox. The gears, initially designed for low-friction movement with specialized grease, become coated in a sticky WD-40 residue. Dust and dirt adhere to this residue, increasing friction and drag, thereby straining the motor and reducing the gun’s rate of fire.

The effects of residue buildup extend beyond the gearbox. In gas blowback systems, residue can accumulate in the magazine valves and nozzle assemblies, obstructing gas flow and causing inconsistent cycling. Within the barrel, residue can disrupt the smooth passage of BBs, negatively impacting accuracy and range. Consider the scenario of a gas blowback pistol’s nozzle coated with WD-40 residue. The residue interferes with the nozzle’s ability to properly seal against the hop-up unit, leading to gas leaks and a noticeable drop in muzzle velocity. Further, the accumulation of debris in the barrel creates inconsistencies in BB trajectory, diminishing shot-to-shot accuracy.

Understanding the potential for residue buildup is crucial when considering WD-40 for airsoft gun maintenance.
