I didn't fee like starting up two threads side by side, so I'm just going to make one thread on both of them. First is why are some guys running just the front flip cover on their scope. I've seen the guys on Art of the Precision Rifle and Lowlight running that setup in the online training videos. Is it just more "high speed"? Second question is, is there an online website for purchasing the IOTA, or do I have to contact Chuck Neller for purchase?
