Does This Set-up Look Good?

[HGM22]

I have a 16'' AR that I want to mount a scope to. I want to shoot at 100-600 yards with it (maybe longer but need more practice). Mostly for ringing steel but I might sometimes want to shoot for groups. I want to mount a magpul MBUS BUIS as well as the scope, and the rifle has an A2 front sight.

I was going to go with the Weaver Grand Slam Tactical from MidwayUSA mounted in an American Defense Recon QD Extended mount:

Does this seem like a good set-up? Will the mount be too high/low for this scope? Could it be done better for around the same cost?

Also, the scope doesn't have parallax adjustment. What kind of degradation of accuracy can I expect at say 500 yards? Up to a full MOA off?

Can't help with the mount.

But parallax is a non-issue at 10x and below beyond, 100 yards or so.

Otherwise that scope would have some method to adjust it.

Normally, parallax only becomes a problem at high power at close range.

Most scopes like that one are set to be parallax free at 100+ yards and beyond.

So I don't think you need to worry about that..

Anyway, if you keep your eye centered behind the scope, it's also a non-issue anyway.

Some of us were killing coyotes and crows with old 6x Weaver scopes at 500 yards before we had been told parallax is bad, MmmKyyyy?

Do some more home work. There are times when 5 gallons doesn`t just won`t fit into a 3 gallon bucket.

Makes one wonder if all the parallax talk is just a marketing game to sell us into new scopes with parallax correction.

Morrey as RC said it's really only a problem closer in at high magnification, most don't even have a setting for more than 200 anyway they go from 200y to infinity at the last step. IMHO they're really important on something you want to shoot really small groups with at 50 yards like my 22lr that wears a 6-18X lol.

parallax is not just talk. it is very simple to demonstrate. all you have to do is secure the rifle and then move your eye around without moving the scope, and you can see how much the reticle moves relative to the target. taht is how much you could be off.

also, most precision shooters will adjust the parallax to focus at mid range so they can watch the mirage for a wind call.

Sav 250, could you please elaborate? I am trying to do research but it is very hard to know where to start.

That setup looks good to me.
I'm a fan of the Japanese Weavers. No experience with that mount, but given that it's a known brand, made in the USA, and costs what it does, I see no reason to doubt it's quality.
No worries about mount height. I wouldn't worry about parallax.

Parallax is real, just not a huge factor for most people

From Leupolds owners manual

It occurs when the image of the target does not fall on
the same optical plane as the reticle. This can cause a small shift
in the point of aim. Maximum parallax occurs when your eye is
at the very edge of the exit pupil (Even in this unlikely event, our
4x hunting scope focused for 150 yards has a maximum error of
only 8/10ths of an inch at 500 yards). At short distances, effects
of parallax do not affect accuracy (using the same 4x scope at 100
yards, the maximum error is less than 2/10ths of an inch ). It is
also good to
remember that, as long as you are sighting straight
through the middle of the scope, or close to it, parallax will have
very little effect on accuracy.

That combo looks good to me for the price.
