When the trigger releases mid-cycle, something has to stop the spring driving the gears back the way they came. That job belongs to the anti-reverse latch.
When one wears or its spring tires, the symptom is a gearbox that jams part-way or unwinds with a clunk, and a sector gear that starts picking up damage.
It is among the cheapest parts in the shell and one of the more common causes of a lock-up, which makes it worth having spare before you need it.

Fit the small spring the right way round. A latch that does not spring back is worse than a worn one.
Frequently asked questions
What happens when one fails?
The gears can run backwards under spring pressure. Usually you get a jam part way through the cycle, sometimes with damage to the sector gear.
Does it come with the spring?
Yes, the small latch spring is supplied with it. Fit both together rather than reusing a tired spring.
How do I know mine has gone?
A gearbox that locks up or unwinds noisily when the trigger is released is the usual sign, though a stripped piston can look similar.
