I should have specified the Mannlicher 93, reading my original post i failed to specify. Guess was relying on the Hembrug part to cover it. Seems to have done well enough, heaps of useful pics to get me thinking.

Anyone know the standard barrel length on a Gibbs rifle?
And that peep site they all seem to have, custom made or a factory part? If so, number etc? Of for one thats close?

Cheers,
Ash.
