I have a problem installing the ejector/interrupter .
The short screw that holds the spring part of the assembly is too short .
The screw will " screw- in " without the spring in place .
The problem is that the 1st-2nd threads are gone .
The only solution I can think of would be to tap the threads a little bigger and use the matching screw--or find a longer one with the original thread .
Has anyone got a plan for me ?

The barrel on this 91/30 is stamped 1940
Thank you,
Mike

Its a metric screw. go to a local hardware store that carries metric screws. Its a .8 X1 IIRC. Just replace the screw. You can get a longer one and custom cut it to fit.

I went to "fastenal" a nut and bolt supplier.
The salesman told me the Mosin screw I showed him is not Metric.
The Russians bought the tooling from the British.The Mosin screws are inch pattern " Whitworth 55 degree pitch "
Russia went Metric after the Revolution--but still make the Mosin screws with Whitworth threads .The interrupter threads and the cleaning rod threads are the same.
I cut the end off of a cleaning rod and made a screw that is longer and works great.
Whitworth threaded screws and bolts were originally used for locomotives .
They do not do well with vibration and are not used for automobiles .
This makes them hard to find.
The whitworth 55 degree thread works fine on firearms .
