my first mosin

[96232]

I purchased a mosin nagant from big 5 and get to pick it up tuesday, I am just wondering if there is anything I should do before firing it? I know to clean the cosmoline out if it and a friend of mine recomended using lighter fluid to clean all the cosmoline out. Is there anything else that a I should check or inspect before firing?

thanks in advance

If you have or know someone who has headspace gauges you should probably get them.

Congrats on your purchase. You will probably want to take the bolt apart to check for cosmoline, here is a link to a great Youtube video showing how to disassemble & reassemble it.

7.62x54R.net is another great resource for the Mosin. Make sure you check the height of the firing pin when you reassemble it, too short and no boom, too long and pierced primer.

I would stick with mineral spirits to clean the metal, of course, I smoke cigars...

Besides the headspace check the firing pin protrusion.

i'm never worried about headspace on Mosins. if the bore is good and the bolt matches the receiver you're more than likely not going to have a problem.

also, if it was imported by Century Arms Intenational, they headspace check everything they have before they sell them. ones that fail aren't sold. i asked them that question and that's what they told me.

thanks for the info

If you google cosmoline removal you will get tons of info. I boiled hot water stuck the bolt
and misc metal parts in a coffee can and pour water on top. Let it soak for a little while
pulled everything out and wiped down with paper shop towels. I used oil to wipe down the
parts to prevent rusting.

This is true.

I use regular unleaded to clean new to me rifles, outside. Lighter fluid is expensive kerosene, which will also work. Unless the stock is heated somehow, it will likely bleed cosmo for years, but it's not a big deal.

i have mosinitus, i have 2 of them but i want another! and after i get that one i'll want another, i can't get enough of these cheap rifles.

I take a can of brake cleaner to all of the metal and I always run Hoppes soaked patches through the bore to get out any copper fouling that seems to always be in there.

I use mineral spirits or denatured alcohol on the wood just a quick wipe down to get the surface cosmo off. Test in an unseen area to make sure it won't do anything weird to the finish. I believe DA dissolves shellac so I don't use it on my comblock guns but works well for crusty Mausers to get some goop off.

Re-oil all of the metal parts. I've used CLP/Remoil If i will be shooting it soon, or motor oil if it's going to be awhile.

If you decide you want to scope it, change the stock or any mods, make sure you ask in the forums before spending your money.

And the Soviets headspaced them, when they refurbed them and arsenaled them in the 60's and 70's. They haven't been fired since, just waiting in reserve for the big one...WWIII.

Also if you bought one at big5 and if you shot it and it blew up on you or whatever i'd think that they could be held liable.
