i keep hearing that the 700ml is hard to clean, i must have rare one then cuz mine only takes a few min. pull 3 allen screws out, remove stock, stik barrell in bucket of hot soapy water, ram patch up and down till clean. dry everything off and throw it all on the bench till yu get time to put it back together.the bolt can be a pain to dissasemble, usually if im in a hurry ill set it in a pan of kerosene till i get around to it.
