First time cleaning my new Kibler SMR. Poured warm water down barrel and set it aside for awhile(plugged touch hole first) When I got back to gun, a black streak had run out of the end of the lollipop tang-stained my beautiful new stock.The darn stuff won`t come off.Where did it come from?? Can`t have this! Probably call Jim Kibler tomorrow and ask him also. Thanks
