The KWA RM4 and VM4 Series Charging Handle Spring (Part M286) is a genuine airsoft replacement part for KWA RM4 and VM4 Series rifles. It is intended for ERG, AEG 2.5 and AEG 3 mechbox platforms, where it fits as diagram part 286 and attaches directly to the charging handle.
For worn, damaged or missing internals, this small spring plays an important role in keeping the charging handle assembly working properly. On a rifle that sees regular skirmish use, replacing tired parts like this can help maintain the correct feel and operation without resorting to guesswork on fitment.
As an original KWA part, it makes sense for players carrying out a proper repair on a compatible RM4 or VM4 build. If you are already servicing your rifle, it may also be worth checking other KWA airsoft parts, gearbox components or replacement springs to complete the job.
Order the correct KWA replacement part and get your RM4 or VM4 build back together properly.
