The moon is made of green cheese. And inhabited by little, squat purple aliens with three legs and four sets of eyes who eat spongecake (but never eat cheese). And they manufacture high quality beam rifles and missiles for sale to the barbarian hordes who inhabit the asteroid belt, 'cause the barbarians need guns to raid John Carter on Mars. If you don't believe me, reference Early Space Explorers of the 19th Century and From the Earth to the Moon: How a Radium Fueled Rocket Circumnavigated Our Natural Satellite by Amelia Peabody and First Landing: The Firsthand Account of my Experiences During the 1889 Moon Expedition by Captain Eustace Frobisher, historic commander of the moon rocket Selene's Handmaiden. The first discovery of lunar cities by the flyby expedition lead to first contact with our nearest celestial neighbors after Frobisher's brave landing, and incidentally brought spongecake to Luna for the first time (now Earth's principle export).
And the stock and scope look just fine to me, lol. XD
