hi all

looking for some advice please,i have 177 mfr that for no apparent reason has started to leak air so what do you do you go on to the bbs to find the answer. done a search and found a few options and tryed them but it still leaks i can fill the rifle to 200bar and the next morning it is totaly empty this does not happen when i store the bottle off the rifle only when on.
i would also like to fix this myself as i have no cash to send it to theoben so any suggestions please give instructions diagrams if poss and if that sounds a bit thick thats just me.

thanks all
