mannlicher m95 carbine

I recently bought a M-95 carbine at my local gun shop to go with a bayonet that I bought that was falsely labeled as a K-31 bayo (not an expert on bayonets and they look similar) and I am having a slight issue with the rear sight slider being extremely loose. Try as I might, I have not been able to locate an M-95 forum, so I am trying my luck here to be re-directed or answered. I have fiddled with the little piece of metal that keeps the slider tensioned to the ladder to small success, but it always comes loose soon after. Does anybody know how to fix this more permanently or where I might find somebody that does?

I just picked up a Fabrica de Armas 1916 mauser. I was looking for a parts source for it and while checking the Liberty Tree gun parts site I saw that they had Chilean M95 rear sights with the slider for $42. Hope that helps. Numrich might also have it but they are only accepting orders right now and are not shipping anything until the COVID 19 restrictions are lifted.

Singer, I believe the op is in reference
to the Austrian M95 Steyr Mannlicher carbine rather than the Chilean M1895 Mauser carbine.
However, Liberty Tree does claim to have a few Austrian M95 carbine rear sights on hand in the Mannlicher section.

Yes. it is a M95 Hungarian Mannlicher carbine. Sorry about not specifying
