Do k31 bores come out mirror or do they tend to be a bit darker? I have no pitting and the rifling is great but I feel like the bore is darker then I'd like. Any suggestions?
Seems to be pretty accurate as well

Thanks
 
They tend to be in much better condition than some others but it's still a (insert age of your rifle here) year old surplus rifle. Some have mirror bores, some have perfect bluing, some have perfect finish. A rare few have all of those and more. If it shoots, you've got a winner.

The best time for being choosy has long past, that's a game best played at the bottom of the market when you can afford to buy ten and pick the best four to keep ;)

That said, it's all part of the fun no?
 
Thanks for the response! And I couldn't be happier with the k31, it functions a1 and the rifle is much more accurate than I am. I buy all my milsurps to shoot and the k 31 is a pleasure in that regard!
 
Grease the bore when you're not using it and patch out the grease before shooting it.
Best to grease the bore when barrel is still warm. Use nylon bristle bore brush to coat the rifling.

Resist the temptation to "Over-Clean" the bore. it is the fastest way to destroy accuracy and shorten rifling life.

How to define the OVER CLEAN?

Do we have to scratch out the copper foil and carbon each time after range or, leave it until it affects the accuracy ( would they affect the accuracy?)

I use the copper brush normally to clean the bore and use nylon one to apply the grease.

I also seal the muzzle with grease when store the gun vertically as I believe humidity is heavier than air and seal the muzzle will stop it from travelling through the bore.
 
I prefer synthetic oil based grease with molybdenum. Any grease is better than none, but keep away from sulfur (corrosive to brass)as an ingredient.

Lubriplate 930 is close. Better if you cut it with 10% Moly powder will get very close to Automattenfett.

Diopter, do you have a recommendation for where to pick up moly powder in Canada? I've been checking out Ebay and Amazon as I wanted to make some of my own moly paste for another project, but it's pretty pricey to ship the small quantities (1oz) from the US. The cheapest per ounce that I've found is Lyman's Super Moly powder, which is in a 6oz container --- that seems like it would last several lifetimes.
 
So I believe the best practice is:

Apply the grease to the bore after the range. This will help to soften the carbon and residule and rust protection.

Use cleaning agent per 300 rounds for a complete cleaning. Apply grease afterwards.

Copper brush has been used by Swiss army cleaning kit so copper-brushing the bore might be alright?
 
Copper brush only need for very old or stubborn deposits.
Patch on a jag will remove most of the filth with the grease.
