Just purchased a Benjamin Trail NP2 and it came with a 3x9x40AO scope. I'm having trouble making sure the scope stays solid in the rings and that the rings stay solid on the rail. I've tried locktiting all the screws and it didn't solve these problems. Just wondering if maybe its the way I'm holding the gun while shooting that's creating more recoil through the scope or maybe I need new rings? Any help you old pros can give me would be great.
