New guy just joined to take part in this discussion. I've had a QB57 for many years that I've tuned, and one of the things I did was to eliminate the trigger slop. There is a metal rod that runs from the trigger blade back to the trigger assembly. I bent the rod at the existing bend,esentially shortening it, and now it's a pretty nice trigger. As for scopes, I found that an inexpensive (Hammers) 2-7X pistol/scout scope has the required eye relief. Mine shoots well, but it's not a tack driver. RC
