I have recently acquired a second-hand CZ 457 .22. The rifle came from the factory without iron sights. When I got it, it had an Excelvan scope (which, from reading online, is a cheap Chinese scope), and no manual for it. The scope is mounted on the gun via a traditional two-ring setup (no Picatinny rail). My question is: can anyone recommend torque settings for the bolts securing the rings to the base, and for the ring locking bolts? They all appear to be Allen 15. Thank you.
