107, I just pull the barrels, use the spray nozzel on the kitchen sinkwith hot water. That washes most of it out. Then use 1/2 paper towel with ballistol water mix wadded up and pushed through. Another pass to dry then 1 with ballistol for protection. wipe the breachface with ballistol, put it back together and ballistol the whole thing. It takes just about the same amount of time as I spent typing this.
