Hi all,

First time visiting these parts and I have some questions...

I will be getting an AR-180B and I already have accessories (scopes, rails, etc.) incoming.

Anyway, the scope is a Weaver K4 (4x) and I will be using Weaver see-thru rails.

I just wanted to know the following:
BTW ammunition used will be Federal-American Eagle 55gr .223 (I have 700rnds sitting here at the moment)



1. What distance should I "zero" the scope at? 200m or 300m or ???

2. Does it matter where along the scope body the rings are placed (i.e. do rings need to be close to the center of the scope, or can they be out towards the bells)?

3. At what distance should I sight in the fixed-iron sights 100m / 200m / etc.


Thanks much :)

I CONCURE BEING ZERO AT 300M IS GOOD, ALL MY GUNS ARE LIKE THAT
MY M-1 GARAND, /303 /K98 / MY MINI-14, ECT.
REMEMBER to do it yerself.............everone aims a bit different .
 
#1. Agree with above, depends on what you intend to do with it. I zero all my rifles at 100m. If I had irons and a scope on one rifle, I would zero them both at 100m.

#2. I would say place them out as far as you can, ensuring nothing interfers with the rings, (like turrets, Adjustible objective -obvious).

#3. Same as #1
 
Thanks... it was going to be for paper punching, but I wanted it for longer range paper punching (I was getting bored of the 25-100m line) hehe

I've done an afternoon of internet reaseach and I've decided to do 300m for both the scope and Iron sights (with correct "L-sight" selected of course)

Thanks for replies :)

Hurry up February!!

:D
 
Here's a table I use:

If you zero at the Åyou can see what your point of impact will be. For example, if you zero at 300 meters, your rounds will be 3.9" above your Line of sight at 100m, 4.9" above LOS at 200 m, 12.7" below LOS at 400 meters. So basically, hold a few inches low at 100, and 200, and a foot high at 400 to get hits.

If you zero at 400 meters, your rounds will hit between 7-11" high at 100, 200, and 300 meters.

It's up to you which way you want to setup your rifle. Basically though if you zero at 100m for a point of impact 4" above your point of aim, you'll have your 300 m zero. If you zero for a POI 7" above your POA, you'll end up with the 400 m zero.

Hope this wasn't too confusing.
