New to sks wanted to find out what is too loose for an sks gas tube when locked it moves a little bit when i unlock it i put an envelope between the gas tube in front and when i lock it it pinches th envelope. will the carbon from firing the rifle be enough to take care of it or should i look into replacing it. if i have to replace where would be a good place to start looking the blueing is mostly gone so i would really hate to replace it because i love the look of it would prefer a fix if necessary.
thanks for any help
