Solidly reliable - Vortex Crossfire II AO 6-18x44mm 1in Tube Second Focal Plane Rifle Scope

So far I'm enjoying the Vortex Crossifre 2 6-18x44 AO scope. It is mounted to .223 Remington 700 Magpul Hunter setup. The scope and the rifle are both better than I am, i.e., if I were a better shooter I'm pretty sure I could consistently keep it under 1-inch MOA at 100 yds. I initially zero'd by removing the bolt and sighting down the barrel. That got me pretty close. I then sighted it in first at 50 and then 100 yds. Again, if I were a better shooter, I think I could have gotten some pretty good groups at 200 yds. As it was I was at least on paper at 200. In terms of useful distance, and given my not-so-great eyesight, I'd say 200 yards is about the limit of this scope. I would need an additional spotting scope to see holes in the paper much further out. The scope held zero well after about 40 rounds. In general the glass was clear out to at least 200 yards. I have no complaints.
