AR Rings

[NikatKimber]

Quick question, if I want to mount a scope to an AR, what is the *proper* height? IE, if I'm buying rings, what height should I get? Med, High, Ultra High. I still have the FSB / Sight on the rifle.

Also, I have a lower end (DelTon) 16" upper, what kind of groups can I expect? I'm curious to shoot it and see what it will do, just for kicks.

It's kinda tough to get the eye relief right on a scoped AR...that's why you see things like the LaRue SPR. Armalite makes a pretty nice one-piece riser/rings too.

As far as proper height....uh...I dunno.

What kind of rear sight do you have on it? That's probably gonna have to go away.

Flip up. It's off right now. I have a set of rings off my 10/22 on it right now with the 6-18x44 Swift from my 700. Everything cleared, and I shot 20 rounds with it. Best group I could get with it though was 1.5" @ 50yds.

3MOA sounds about right for a 16in DTI.

I was wondering if that might be the case.

You need the ulta-high rings unless you have some kind of risers. There are many variables concerning accuracy. A lot will depend on what ammo you're shooting. Also, a non-chrome lined barrel will normally group better than a lined one.

These are about the cheapest, decent rings I've found for a flattop; http://www.midwayusa.com/viewProduct/?productNumber=113490
They're not pretty but they work.

The Armalite works really well. IMHO its the correct height. I use one on my .243WSSM AR
That being said, I bought a Rem R-15. I wanted the matching camo scope and rings. I found them at a gunshop. They told me that even though they were medium height rings, I would need the additional "riser" to get them to proper height. They were correct. This works for my "sight picture requirements". They may work for you or not.

I have this scope:

with these rings in the high (3/4") variety:

and the fit was perfect; looked like this:

I'm curious why you need to have it at a certain height? As long as the bell clears the handguard that's all you should need, right?
