Thinking of buying a Bushnell Banner 3x9x 40 scope and can get one with 4" eye relief for 6" eye relief. Which would be best for my accura? Would 6" hurt anything? Would it make a difference with the 6" if i got 4" or 5" away from it or closer? Just want to make sure i have enough eye relief. Appereciate any input. Which would you choose?
