View Full Version : 1st Mosin 91/30 Hex received today!

December 3, 2008, 01:17 PM

I received my C&R about 2 months ago, and just recently placed an order for my first Mosin91/30 Hex 1921r, note I said 1st! Not last by any means...

It arrived today and looks very cool..numbers all seem to match, well, the ones I know of..LOL...

There is enough Cosmo on it to sink a battle ship...so what is the preferred method of removing said sticky stuff?

Now I am just waiting on the ammo to come in so I can take it down to the range..

Also, what are the accessories for that came with it? I can figure out the cleaning rod, and patch rod attachment...as for the rest, I'll search...

Pics will be up in a few...

Congrats on a good rifle. I use gasoline to remove cosmo.

I used mineral spirits, and gun oil....cleaned up right nice...

Have to figure out how to check head space...then wait on the ammo to come in so I can test fire her..

Either way, was a blast cleaning it up with the help of my 16 yr old...Now he has the bug and we haven't even fired the thing yet...That and he's a history buff...he was going on and on about how this very rifle could have killed people decades ago...I just smiled...it's all about the little things in life, that's the good stuff...

There are nearly as many ways as there are forum members. Some use low heat, some use solvents, some use a combination. The heat users use home-made ovens (trash cans, light bulbs, something to sop up the mess), steam, even the sun, though that doesn't work as well this time of year. Cosmoline starts to re-liquefy around 120 F. The solvent people use everything from gasoline to mineral spirits to oven cleaner.

I prefer a mineral spirit wipe-down of the wood and a mineral spirit soak of all the metal parts, and a thorough cleaning/de-coppering/de-leading of the bore.

Hi, I didn't soak the parts, I just wiped them down with Mineral Spirits, then coated with a little gun oil..
I suppose that I might be doing it again after a range day.
The barrel looked very clean, I only ran a swab MS through it a few times and then a little gun oil..
I will probably sand down the wood once I get moved, don't really want to start any projects right now, as I have too much on my plate as it is..
I am ready to buy a dozen of these things already! Can't wait to shoot it..

Soak the bolt, at least. It's easy enough to remove and set in a cup of solvent for a half-hour or so. Re-oil or re-grease and then be on your way.

There's always a remote chance that too much or dried cosmo in the bolt could affect the operation.

Good idea, that is easy enough to do..and it makes sense..

Will it hurt these things to be dry fired? My assumption is that it is not good for it, unlike an AR for instance.

Dry fire won't hurt it. Is Russian rifle, built like tank......
The teardrop shaped thingy is your all purpose tool.
Screw driver on narrow end, the notches are for checking the firing pin protrusion and the big cut-out is to help take the bolt apart.
check out
