On my Dar 22 cal, the baffles are placed this way,Square baffle first over the end of the bbl, the little reduced diameter lip faces towards the muzzle, the next round flat faced baffle, large open end sits on top of the square baffles lip,then the other round baffles follow suit, stacked accordingly,and all the flat faced ends of the baffles face towards the muzzle,the threaded disc tightens down to hold them in place etc.Hth's,Don
