- description
An anti-reversal latch is a small ratchet that lets the gear train turn one way and refuses it the other. Without one, a compressed spring would simply drive everything back the way it came.
That counts most at the moment the gun stops mid-cycle. The latch holds the position rather than letting the spring unwind back through the gears and out through the motor.
A latch that has rounded off slips under load, and a slipping latch is how a gearbox comes apart in a hurry. It is a cheap part standing guard over expensive ones.

Our supplier lists this specifically for the R85. We have not found it confirmed for any other platform, so we are not going to claim one.
Frequently asked questions
What happens when a latch fails?
The gear train can run backwards under spring pressure. At best the gun jams. At worst you strip teeth or damage the shell itself.
Does it come with a spring?
Our supplier does not list a spring alongside it, so assume the latch only and hang on to your old spring until the new part is seated.
Will it fit other gearboxes?
It is listed for the R85. If your gun is something else, compare the shape against your existing latch rather than assuming it carries across.
