Thanks MidlandMan. Today, after shooting it again, I took it apart. I encountered the 5/32" allen bolts on the mag plate/stock mounting screws and the 1/4" allen bolts that hold the trigger and barrel clamp down. I had watched the U-Tube "how to" videos and still managed to tinker it back together. I did not remove the ejector from the barrel as I could clean the barrel with it in place. The rifle was not really that dirty so I don't intend on doing this that often. Next time I will grease the threads on those screws. Cross threading the bolts can sure destroy the receiver of this gun.
