According to the most recent information provided by Ruger, this part is currently listed as discontinued.
That does not necessarily mean it is gone permanently. It simply means production has ceased for now.
We have already communicated up the chain at Ruger that there remains continued customer interest in this component.
If this is a part you would purchase should it become available again, we encourage you to sign up for back-in-stock notification.
Documented demand matters.
When manufacturers evaluate whether to justify another production run, verified customer interest is often the deciding factor. If sufficient demand is demonstrated, the tooling can likely be brought back out and production resumed.
We will continue to make the case.
