Chasing power with this gun I have found a few weak spots, namely the cocking rod. I have bent a couple stock rods, made my own hardened rod which I snapped, and broke the rod return guide. So, in talking with Rallyshark I decided to somewhat copy his set up. Now the return guide is made from stainless so it won't flex and snap off. And the secondary rod is just a guide rod that is solidly fixed with a set screw in the front scope mount and also goes full length into the second scope mount. I think now I have something that will last.
