Indians For Guns

any idea what this contraption is?

Blank firing device/muzzle cap for the K-31.

Now ask me how I know?
Hint..

Wonder what would happen if a live round is let off with that thing on.

Never seen one,Naga.Thanks for that pic.

Lots of interesting things happen. None of which are desirable.
At the least you ruin the crown, at worst Kaboom.

try harder MoA

Muzzle cap/sight protector: Yes. Blank firing device: No. If you fired a live round without the cap taken off, you'd put a hole through it, maybe blow it off. The rifle wouldn't be damaged. With a blank, you'd just blow it off.

it seems that every one is going for one of the following.
muzzle cap
blank firing device.
you all not seem to be sure, so lets move on
which rifle is if for?

Not for the K-31. Not for the K-98, or G-98.

Snow and Mud Protector for the muzzle.
Marksman

Ah, but which Schmidt-Rubin?

Naga: The Schmidt Rubin comes as a K-11 or K31. The caps are interchangeable.

If I can find mine I will take pics the next time I am home.

MoA: And you will find that you are mistaken. The K31 cap is different from the one Nags pictured. And if you are right about the K31 and Model 1911 carbine caps being interchangeable, that leaves the one that you forgot, the Model 1889.
Now, the Model 1911 carbine and rifle would take different caps; but again, Nags' is not a K31 cap. Cheers.

oh Lord , have i opend a can of worms or what

Well technically there are also the 1889, 1897 Kadet, Zfk 55, Zfk 31/42 et al, but that is splitting hair.
The parts interchangeability between the K11 and K31 is slim, but does exist. Also if we really want to be precise the K31 (series) is not really a SR.
