I am thinking of putting a scope on my new generation Mini-14, it came with the rings and I was sizing up a traditional 3X9 scope last night to get a feel for how it goes on the gun, might go with a fixed 4 power though. I may also get a M77 Hawkeye down the road and it uses the same style scope mount. How stable is this design, does it need to be periodically checked for tightness like the Remington Model 700, etc?
