Hey Fourm,
One of the cylinder return springs (part 83) snapped on my Mac-11 (it has been almost endless problems for me) and the gun is out of warentee. I am capable of installing the part myself however I am unable to remove part 123 from part 19 and also part 67 from 19 how would one go one doing so (as to replace the broken cylinder return spring(short of spending the $19 for the whole assembly)

   I am self tought on working on my Mac but I have changed my Cylinder Return Springs several times.
   Just from memory without taking apart my gun I have this to offer.
   There is a push pin towards the front of the Upper Frame #2. Take note of the notch in the front of the Inner Slide Housing #67 that this pin goes through. When this pin is removed #67 and #19 assembly should slide apart out the back.
   To remove the Main Seal Base #123 you have to remove the Main Seal Base Screw #99. Then the Main Seal Screw Base Screw Washer #71 and Cylinder Return Spring Retaining Pin and the Main Seal Base #123 should come apart.
