Cleaning a Mosin Nagant 91/30 bolt

    Hello all, I ordered a Mosin Nagant 91/30 rifle. As soon as I get it I will give a good cleaning.

    I am pretty well versed in barrel cleaning as the Nagan is basically a 30 caliber rifle I have all the brushes/patches/solvent etc.

    I have been reading and it appears to me that disassembling the bolt would be unnecessary for proper cleaning.

    Can you just spray some Hoppe's #9 on the bolt, let it soak, scrub with brush, spray off with Gun Scrubber or brake cleaner, and then oil bolt thoroughly.

    I have read that some folks use kerosene, mineral spirits, or diesel fuel to let parts soak.

    I do this method on my Mini-14 and everything seems to work very well, although the Nagant bolt seems to be alot more complicated than the Mini.

    Taking the Moisin bolt to pieces is no big deal if you know how and requires no tools. For routine maintenance I normally just remove the bolt head and give it a good cleaning while the rest of the bolt gets wiped down.

    Remember that the ammo shot in the MN is corrosive so use a solvent that will get rid of the water absorbing salts deposited in the bore when shot. Some folks use hot soapy water or windex for this purpose.

    That ammo is going to be corrosive primed. It really isn't any big deal, just clean your rifle properly. In the instance of the Mosin Nagant, disassembly of the bolt makes cleaning the firing pin tip much easier. Firing residue will tend to collect there.

    This ammo should be OK. I had one blow up on me a couple of years ago in a PSL. Not sure to this day whether that is due to the rifle or the ammo.


    Headstamp information:


    It was a nerve wracking experience, nonetheless.

    There is much written on the net about the Mosin Nagant. It is simple and robust and reasonably accurate. Cleaning the cosmoline from the chamber can be a challenge, and if left there, will make opening your bolt an exercise in frustration.

    Good luck with your new rifle!

    Yes, I called AIMSurplus and they said all their military surplus ammo is corrosive primed. No biggie, just flush the barrel out with hot water.

    I have a bit of that same ammo and my Mosin loves it. Just clean your rifle well and it should be fine.

    That is true only of U.S. & NATO GI ammo.

    The communist countries were using corrosive priming well into the 1980's, and maybe still are to the present day.
    Unless it is commercial Wolf or Brown Bear, I would consider all mil-sup 7.62x54R ammo corrosive and clean accordingly.

    Can't wait to get the rifle. It should be on the way to the FFL.

    I figure I will spray it down with Windex after shooting, run some hot water down the barrel when I get home, and clean like I usually do.

    I am spending about $235 on a rifle and 500 rounds of ammo. Pretty cheap in today's market.

    Any tips on getting the cosmoline out?

    Go to one of the pages dedicated to this rifle, I know of at least three, and search the threads here and you will see that this subject is addressed numerous times.

    Take the action out of the stock, put on old clothes, and go to the car-wash after hours.

    The attendant will go ape-shxx if he catches you getting cosmoline all over the car-wash bay.

    Make a long tray fill it with paint thinner and let it soak, wipe it out, soak it again.

    I suggest you get a copy of 'Small Arms of the World' from e-bay. It will have some pretty great information for stripping all sorts of military arms, including the M-N and it's bolt. Lots of great cutaway and function illustrations, too.

    You'll love the mosin. They are much more fun to shoot with the bayonet attached. :rolleyes:

    As far as corrosive primers, the commies used it because it (at the time of it's manufacture) had a longer shelf life than noncorrosive primers.

    One quick tip to add-
    Make sure you get the bolt face really good too. If you look, your mosin probably has a ring of pitting on it. Most do. Before you put the rifle in its case to take home from the range/whatever, make sure you at least put some solvent there.

    Clipper: In reference to the "small arms" book. I noticed a few different ones on Ebay. Is there a particular one that is better than the others?

    They're all pretty much the same, but the later editions probably have more up-to-date coverage of sporting guns and latest military variants. Mine was printed in 1968...

    You can easily reassemble the bolt if you want it get disassembled. Watch how it breaks apart and it should not be heard to put back together.
  20. How to get cosmline out of your Mosin Nagant?

    the one way i got it out was to just give it a through cleaning. but the other way that i have herd of that really works well is putting it in a black plastic grabage bag and stick it out in the summer sun. it mite sound funny but really works. but if you cant wait for summer like me just give it a good cleaning. if you ever want to fix your sticky bolt problem if oyu have one just take a buffer brush or a shotgun bore brush with soft fluffy pink stuff and put it on a electric drill then really fast like motion clean the bore out really nice and then stick #9 hoppes gun oil in it or your fav bore or lub oil to keep it nice and smooth. i will try to get a vid of me cleaning it up on you tube if you watch that at all my channel name is> (12Armystar)

    nice talking to you> evan
