I have decide to upgrade my sks a little bit, ghost ring and scope mount,ghost ring and scope mount. I plan to get a choate mount. Which ghost ring do you guy recommend,mojo or tech sights? First of all, will the scope mount affect the view? To those who has tech sight on their sks, is it easy to take down the rifle? Will tools be needed for rifle take down? Does the sight hold zero after te take down?
