Nuprol M4 Safety Lever

The Nuprol M4 Safety Lever is a replacement internal gearbox component designed for M4/M16-style AEG airsoft rifles using a Version 2 gearbox. It is responsible for controlling the fire selector system, allowing reliable switching between safe, semi-automatic, and full-automatic firing modes.

Manufactured from durable reinforced polymer, this safety lever is built to withstand repeated use inside the gearbox while maintaining accurate interaction with the trigger and selector plate system. It helps ensure proper safety function, preventing accidental firing when the replica is set to “safe,” while supporting smooth and consistent operation during mode changes.

Ideal for repairs, maintenance, or gearbox rebuilds, the Nuprol M4 Safety Lever is a simple but essential replacement part for restoring proper fire control functionality in worn or damaged M4 platforms.
