To install on Colt AR-15, is 6 enough? 10 seems like most likely but 12 little more. 6 is 22' view at 100 meters, 10 is 13' & 12 is 10' view. Will use normal target shooting, coyotes & prairie dogs, no deer or large larger.

But would be serrogate for others in load develope if needed. Thanks for your thoughts & input.
