Re: Scope mounting for dummies
If you have an AR, I guess it is an AR-15 or equivalent. If that's the case, the flat-top or riser top upper is going to have a Picatinny rail, using Weaver style rings. Should be well centered for windage when you mount it. Like Jim says, a new scope should be mechanically zeroed out of the box. If not, zero it like he said, very gently. At 20 yds, adjust it to impact approx 2" below P.O.A. It should then print at 100 yds. Once you find it, set it where you want it at 100 yds and start shooting for groups. Then using the most accurate load, move out to 200 and set it. Most target scopes will then let you zero the knobs. If it is a .223, the 200 yd zero is a good place to leave it, and then shoot for your come-up at whatever ranges you expect to hunt. Write your clicks down (or #'s and clicks) at each of those ranges, so you don't forget them. Lots of ways to keep them with the gun, like type up a card and tape it to the near side of the buttstock toward the back, using good clear packing tape. You're on your own doping wind, I wouldn't give anyone advice on that. It's a learned skill.
There's probably lots of better ways to bring an AR in, but this is one way.
Good hunting, Tom
On edit; britz, I got to try the mirror thing. It seems that you might also be able to watch reticle tracking that way!
