Fixed an annoying problem

Gentlemen: Have you ever noticed that you cannot tighten the screw that holds the block in the reciever? As a result, after you have levered it several times( 10-15), the screw starts to back out. If you did tighten it, the block is pinched by the frame, locks up and won't cycle. You could loctite it in place but then you have to take it out to clean the block. I had ordered quite a few parts (screws, springs, ect), so looking through them I found one that was a thread longer and so I had a very small amount metal removed from the back side of the screw head.  Take it off 1/2 way to the bottom of the slot.......    Now it works perfectly. You can tighten it without pinching the block.    Hoot
