Thanks for the reply I have done that cleaning you stated several times. Now do they have these new mags that will fit the 62/64 rifles, I just purchased 2 mags for it they all look the same. Also as to what part of the feed ramp you talking about tweaking with needle nose pliers. On 2 of my mags there really isn't much left of the feed ramps on the mags. Again thanks for the replies you got me thinking.
