Thumbs down on Leupold MK 4

Even though this post started out being a personal choice post , it has grown into
a fairly good debate.


But it does bring up an interesting question .

I know that most will say that they know how to adjust a scope properly but it appears
that some do not, so I will make an attempt to explain how. and if there is a real scope
expert member or sponsor I would appreciate there chiming in.

First there are different methods of adjusting a scope properly depending on the type,
power,maker/brand and distance.

There are three things that I consider important.

1= ocular focus. This has to be set right, or the cross hairs will be blurred .So I adjust this first
buy looking through the scope in the normal shooting position and starting with the adjustment
all the way in and slowly turning it outward focusing on the cross hairs, they will appear to be
double until they are focused and then they will become very clear and crisp. some times you
have to go past to go out of focus and then return to center, before you except this as correct
close your shooting eye for a second then open it and see if it is still in focus,(The human eye
is a marvelous thing and it can do the correction for you if you allow it to) so by closing it and
then re opening it you will get a good setting. after this is done I place a small mark with a
permanent marker on the two mating surfaces for later adjustments if it is moved buy accident.

Now the next thing is to find out if your scope has parallax.
The way to do this is to set the scope on a rest or sand bags and look at a target 200 yards
or more. with out touching the rifle place your head in the shooting position and while looking
at the target through the scope move your head up and down slightly (Bobble) .If the cross hairs
move up and down you have parallax. (Normally fixed power scopes below 9 power don't have
very much or none ) that's why lower power scopes don't have objective lens with parallax
adjustments. If you do have an adjustment and you do see the cross hairs moving when you
move your head then adjust the objective parallax untill it does not move. (Some/most will have
yardage numbers on them ) "DO NOT GO BY THESE" remove the parallax first and then you can
check the yardage because these numbers can be off just enough to add parallax back in the
scope. Note Parallax will/can ruin a good group and a good shot . I have seen scopes with 2
and 3 MOA of parallax at 100 yards so the 1/2 MOA rifle may become a 3 MOA rifle because of
parallax.

Some of the newest scopes have a side focus and an ocular lens focus . the side focus is a way
of removing parallax and doing a fair job of range focus at the same time. again dont worry
about the numbers just get the clearest picture.

All scopes are not created equal so the adjustments are/may be different so read the
instructions (Something I have a hard time doing) in order to get the best results from
your scope.

Try adjusting your scope and maybe this will put new life in that old scope and those tired old
eyes.

For some, there is alot more to scopes than glass.
Ya know, this mud sling at Mk4 could've been at NF NXS, as the glass is exactly the same quality between Mk4/NXS.

I prefer Mk4 scopes for their field functionality.
Wish they had better Glass? Yes of course. Wish better glass scopes matched Mk4 functionality. Yep. But until either happen, I'm getting more used to Mk4s, and content with it.
 
I've profited from my thread ,I'll pay attention to the focus adjustment rather then the side parallax . Met a couple shooters that claimed to be former soldiers /snipers in Iraq and one said " They use MK 4's over there. Others have a S&B mounted. So obviously the military believes MK 4 are the right tool for the battle field. My bias with Leupold and NXS is simply the price ? My rifles live in a safe or a padded gun case when in transit and I'm very careful with them in use. No doubt my 6500 one day was right on target and a few weeks later after a hunting trip or two its of and needs re-adjustment . I just bought my IOR so we'll see how well it holds after a few trips into the field........... Happy shooting and Long Live the NRA

WTG, rocky start but excellent end result. Please keep us posted on you IOR. Happy safe shooting, cheers!
 
Is the animal dead? You think maybe it is just taking a nap there in the sun?

It looks like it just woke up from a nap to me :)

Are ya sure you shot it? :D

Of course there's more to scopes than glass. While NF isn't exactly known for having the best glass, it is known for its quality, strength, durability and reliability far exceeding that of Leupold. That's one reason less mud is slung their way.

Of course functionality in the field is what matters, under most conditions glass quality is only icing on the cake. But are you really contending that no scopes that have better glass can match the functionality of a MK4? In what way? Not just NF or IOR but S&B? Vortex Razor? Premier? USO? Hensoldt?

None of those can "match the function" of a MK4? That's just silly. The fact is MK4's lack many functions compared with those, in addition to glass quality. That doesn't mean they're bad, or can't get the job done, but the notion they can function like nothing else can really is silly.
 
As this thread demonstrates, one reliably good thing about Leupold is if and when you want a scope with better glass, you will always find a buyer and they hold their resale value very well because of Leupold's top-of-the-line customer service, repair, lifetime warranty policy and reputation. I didn't have any trouble selling mine. In fact, if you can find a used one to purchase, you can use them for a good while, decide whether or not you like them, and if not, get your purchase price back out of them without too much trouble.
 
Jon, I have several NXS scopes as well. Nothing wrong with them, but they do not match Mk4 scopes.
They mount higher, are way heavier, the eyepiece turns with power changes, and NF does not offer OEM flip-up lens covers like Leupold's Alumina. On the bright side(literally) NF offers nothing that betters mk4s for me.

As well as glass, there are many attributes to consider(to score) in scopes, and the scores can be taken as a total. In this respect, I consider the Mk4 as the best overall.
For me, there is weight, mounting height, cost, field adjustable turrets(not capped), durability, glass, side focus, second focal plain, reticle subtension, MOA adjustments, repeatability, eye relief, options, accessories, service & pluses and minuses.

A lot of good scopemakers out there offer models with this or that scoring better than a Mk4 in one or two areas. They always score worse in others though.
Therefore, regardless of score, they do not MATCH Mk4s.

Analogy -when you consider the Corvette a standard. It could not be said that any of the Ferrari, Viper, Mercedes, NASCAR, etc, MATCH the corvette, until they first do so.
Their scores go all over the place, never matching the standard.

So an objective assignment of the attributes -important to me, applied to any current offering out there, always leads back to my standard -the Mk4.
When that changes, when March offers a Mk4 match -with ED glass, I'll pull out the checkbook believe me.

Now if FFP and MIL adjustments are part of your standard, and weight doesn't matter, then the Mk4 would score differently for you I'm sure.
But keep in mind that anything that can be done with a scope, can be done with a Mk4. So it will get the job done, as any standard should.
 
For the record, my 2 favorate scopes is the 5.5-22x50 NXS and the ORIGINAL mark 4 in both 10x and 16x fixed power. They are my favorates because I cannot afford the one I would rather have.

If I am going to have a variable power scope with average glass with a big objective, I would rather just get the NXS over the mark 4 variables. However, the fixed power mark 4's are MUCH lighter as well as crisper clearer than the NXS and are every bit as bomb proof if not more so as the NXS. Both have very accurate, reliable dials.

Any time you eliminate the variable power, optical performance increases noticabley. I spend most of my time behind the mark 4's.

My 338 Edge sports the NXS most of the time and my 308's sport mark 4's most if the time. When I am in the backcountry on a pack in hunt, you can bet that regardless of which stick I have in my hand, it will be wearing a mark 4 fixed be it 10x or 16x.

The biggest reason that these are my 2 favorates is because I am VERY hard on equipment. I refuse to let my scope be the weak link when I am setting up on a shot on the critter I have waited 1/2 my life to harvest. I have knocked other scopes out of zero be it on the 4 wheeler or out climbing in the rough country. I have HAMMERED both my NXS's and mark 4's and none of them have ever once been knocked out of zero. They are both very robust, precise and smooth operating. Is the glass among the best? Nope. Is it sufficient? Yes. If they were not, be assured that I would not own them. I can forgive sub Swarovski glass for a scope that will be dead on and track accuately when I need it the most. As most of you know, I went on an Arizona coues hunt in December. I waited for 16 years of off an on applying for the hunt and applied for the last 8 years straight. The last thing I needed was a scope that had been knocked off of zero when I set up on the buck of my life. My cousin had his scope knock off of zero from a mediocre fall. Fortunately we caught it when we went to the range one afternoon. When it came down to the wire, he ended up shooting his buck with my rifle. Why? Because he knew without a doubt that my rifle and scope combo would get it done. Since he shot his in the last hour of the last day, he couldnt afford to miss as he would have not had another opprotunity.

I am sure there are other bomb proof scopes out there. For me, I am going to stick to what I know works. It is scary to think that I have over 7500 bucks worth of optics. I am not willing to part with any more cash just to see if a scope will hold up to the abuse I subject them to or not. Unfortunately, I probably wouldnt find that out untill I was shooting at my 1st 40" or bigger dall ram. IMHO, this is not the place to figure this out. Sadly, there are few enviornments that will subject as scope to the type of punishment that will test its reliablity before I go to harvest a ram. So I would rather just keep using what keeps the freezer full and my taxidermy bills high.

I set up on a bench looking at details of a hillside of houses 2 miles away to compare
a) Leupold Mark 4 8.5x25x50 LR/T 56090
b) IOR 2.5x10x42

I put the IOR on 10X and got the best resolution I could with just the eyepiece to adjust.
I put the Leupold in ~10X [going back and forth looking at both scopes until they seemed the same magnification] and got the best resolution I could with the eyepiece and the side focus to adjust.

The IOR was better.
So I cranked up the power on the Leupold until the resolution on the decking material of those houses was the same.
It was ~12X, scaling off the power ring markings for [magnification/rotation] gain and assuming the Leupold had started at 10X.

Only when I go back and forth with the scopes on the same object can I see a difference. The memory of such small resolution discrimination does not last more than a second or two in my brain.

Is the Mark 4 as good as the IOR?
No.
Is the Mark 4 usable?
Yes.

Is the Super Sniper 20X usable?
No.
Is the Bushnell 3200 4x12x40 usable?
No.


How low WILL I go?
I have shot (8) deer in the last (2) years between 329 and 510 yards with a Leupold VX1 2x7x33.
 
Three interesting points in the recent posts.

First the fact that fixed power rifle scopes ( and spotting scopes) are easier and cheaper to build to high quality optical properties than variables.

Second is to detect small differences in quality you really must have the scope completely still. I just do not know how people can go out into a store parking lot holding a scope in their hand and look through it and see those differences.

Third, optical devices are built as a set of compromises according to the established principles of optics. The human eye is variable from individual to individual and It has been a great surprise to me how many hunters have some amount of color blindness and/or eye sight problem. If an optics designer decides to maximize a scopes performance in the blue green spectrum (as Leupold has done) and a individual in not very sensitive to blue green light then they will certainly not see much benefit from that aspect of a scope. If a person's night vision is excellent then they may not see much benefit from a large objective lens and so on.

On the last point I will add is that if you should wear glasses and don't, or if you if you need to have the prescription changed because your current glasses do not provide the adequate correction to your vision then you are not in much position to judge scope quality.
 
+1 on what BB said.
It always shocks me what people do with scopes. I have seen people want to return scopes because they say the one they bought is not as clear as the display model they looked at when they were looking for a scope only to find out They had never adjusted it to their eyes. Just took it out of the box, looked through it and said "Wow this isn't the same as the one on display"
There are a lot of people out there that have bad eyes and just are too proud to wear glasses but cannot get a scope to adjust to their eyes and yet feel qualified to say whether a scope is good or bad.
If you know what your doing it only takes a minute to focus a scope to your eyes but if that person does not know how to do it correctly they just complain about how bad the scope is and do not do anything about correcting the problem.
 
I have a Nightforce2.5-10x24, a Zeiss Conquest 6.5x20 and a Leupold Mk 4 3.5x10 with M3 turrets. I bought the Nightforce last after stopping at a dealer and looking thru one. The glass was just pure crisp and clear and the etched reticle was really sharp. The first scope of the three was my Leupold as I have always owned nothing but. I had never looked through a scope as clear at the time. My only complaint with it is that it has backlash in the side adjustment and if you don't start at infinity you can eliminate parralax but have a blurred image. If you start at infinity and stop as soon as the parralax is gone then the scope is crystal clear. The Zeiss is clear and my only complaint with it is that the adjustments are backwards from the Leupold's that I am used to. I bought the Nightforce thinking I would sell the Leupold to help pay for it as I think it will prove to be a very durable hunting scope and the lack of parralax adjustment is user friendly for the distances I shoot would make it an ideal large game scope. The Leupold is bomb proof also and if it wasn't for the lash in the parralax I would have never bought the Nightforce. The Zeiss is on my varmint rifle as I like the higher magnification and I use it at the range more so than the high power rifles. So there it is, I have a Chevy, Ford and a Dodge and which one is best? I could not tell you as all three are crystal clear, very repeatable and the Nightforce and Leupold appear to be bombproof! I really like the reticle choices that Nightforce offers but I am also very fond of the Leupold cpc which can be had from the custom shop. One thing is for sure, they are all better than the Weaver K2.5 with a Lee Dot that I used very successfully in my youth when I thought I had died and gone to heaven when my dad replaced the Marble peep sight on my trusty Springfield.
