91/30 Sniper Help

[Patrick Chadwick]

Surely if it is a genuine ex-sniper, then it must already have the holes? They may have been plugged, but you will still be able to see the correct position.
The corollary to this remark is:
If there is no sign of any mounting holes, then maybe it is not a one-time sniper.

Assuming that it was genuinely set up with a PU scope, once upon a time, but the holes have been plugged - hopefully by inserting threaded stubs and filing them flush with the receiver wall - then it might even be possible to simply drill through the plugs and remove them with a broken-tap extractor.

In any case, I agree with Aragorn. You ought to be able to do this yourself.
