    I have aquired an M1 Garand in 30-06 that has a dark bore. Is there a way to clean up a dark rifle bore without having to rerbarrel?

    Have you fired it yet? If so, how does it shoot? Is it accurate?

    My suggestion is to really clean the barrel and chamber well, then run some Sweet's through it before you do anything else. You may be surprised.

    Good luck, let us know how it turns out.

    I wouldn't firelap a Garand due to the gas system getting stopped up. You would then have to give it a REALLY good cleaning. If it has a dark bore but still shoots accurately, don't worry about it. Do you have access to a borescope? Check for pitting.

    I cannot get to the range due to Ohio weather being what it is. I will try the Sweet's bore cleaner and see what happens. Thanks! muzzelpup

    There is a small amount of pitting I could see by eyeballing with a patch in daylite. I will try putting Sweet's thru it. I'll probably get it from Midway. Won't get to the range probably til spring. That will give me opportunity to check out gas system. Thanks! muzzelpup

    May want to go with what Bear says on this.

    Another thing is the idea of running abrasive media, even fine, through the gas system.

    What about a good coating of Naval Jelly ( no, no jelly in my navel ) and then a good cleaning? Do you suppose it would have much effect? muzzelpup

    That would be worth a try-just follow up with a brush and DON'T try to shoot it out instead of cleaning it out.

    Dark but strong

    I ended up putting a bolt gun back in shooting condition (started out as a barreled receiver) the barrel was dark but the demensions all checked out ok
    My guess is in your case to check your throat errosion, dark bore would pick up fouling more, and being a semi auto that might effect accuracy, other than throat errosion and the muzzle crown, thers not much one could do short of repaceing the barrel, if you use a electro bore cleaner it wouldent necessarily brighten up the bore, mabe hand lapping could smoothe up the rough spots, but this also involves removing material from your barrel, something you wouldent probibly want to do this would change your bore diameter, My guess is if you intend to shoot competions get a new barrel.
    As in my case the milsurp 1927 dated carcass (P-27 mosin) the finnish was gone and the collecters value gone, still ended up being one the most accurate milsurp bolt guns I own so far, it still has a very dark bore. I can hit a pop can at 100yds with it I'm content as is.
