I recently bought a Savage 10MLII. I read in the on line manual that the vent tube needs to be replaced after a number of rounds. Not knowing the history of the rifle I thought I'd replace it so I'd know it was good. I didn't get a breech plug wrench with it either. I found one on line but it's not he standard wrench. If anyone has source for the wrench and or the tube I'd appreciate it if you could point me in the right direction.
