Description
Bolt M4GB06 (Gear Latch)
This is a gear latch from Bolt Airsoft for its M4 gearbox, listed under part code M4GB06. Bolt is a Taiwanese manufacturer known for B.R.S.S. recoil-system AEGs, which use their own gearbox parts. Small internal latches like this can wear or break, and a genuine Bolt replacement is the surest way to get the right fit.
When a small part fails inside a gearbox it can stop the whole rifle from working, so having the correct spare means a quick repair instead of a long wait for parts.
What a gear latch does
In most AEG gearboxes the latch that engages with the gears is the anti-reversal latch. It stops the gears spinning backwards after the trigger is released, holding the spring tension and allowing the motor to start the next shot without strain. Bolt’s own description of this part is not available to us, so compare it with your existing part and the product photos to confirm it is the one you need.
Fitting
Fitting a latch requires opening the gearbox. Before you start, make sure the spring tension is released, as the anti-reversal latch holds the gears under load. Note the position of the latch spring before removal, and ensure the latch moves freely once fitted. If you are unsure, ask an airsoft technician.
