AR-15 Zeros and Trajectories

[Quentin]

Thanks Molon, excellent information as usual!

I've got a question, I already had my 20" ar 15 zeroed with the Santos method so all I did was add 4 more clicks. ( 6/3 detachable carry handle with half clicks). Theoretically, should I have to change the elevation on the front site despite being on target at 50yds?

Molon, you should write a book! Or someone should hire you to write a book...

With the information you provide, as well as the excellent photos, it would be a good seller I believe...

Awesome! But where's the 75 gr data?
(sorry, I had to ask...)

I didn't want this thread to get too complicated, so I just used the ubiquitous M193 and M855 for examples. I'll post another thread with reams of 75 grain data.

Though you (and everyone else) already know this: great thread.

Fantastic explanation..... Breaks it down so it's easier to understand.

Thanks for doing this! Great help to some of us that aren't as sharp as others.....

I appreciate the fact that you are keeping this thread going. I zero at 50 yards, then make minute adjustments at 200 yards. Out of my carbine, I can raise the rear sight 3 clicks and be dead on at 300 yards. With the 200 yard zero, I just hold and shoot from 20 yards to 225 yards.

Thanks for having this a sticky. It will help at the range this weekend.
