It's pretty easy to see, it's all over the forum. Go to the rifle section and ask what scope to get for $150. Ask how much your budget SHOULD be. You'll soon find out that the scope should cost at least as much as the gun, some say 50% more! I've even seen double.
That's what the OP is talking about. Not just having an appreciation for finer things, not simply owning expensive guns but looking down your nose at people who can't afford them or don't want to, while telling them all the reasons they're stupid or foolish for not spending a months take home pay on an optic.
Hmmmm....well, scopes are interesting. I'm not qualified to tell anyone what $150 scope to buy as I've never looked into optics of that level so I could not make a recommendation. However, I can tell you that there are real performance differences between products at different price points.
I've been professionally involved with optics for about 45 years - and you generally do get what you pay for in optics if you know how to choose and evaluate the lens, binocular, telescope, or rifle scope - and, most importantly know how to define the performance and features you need in an optic.
Most mid-range scopes will give you 80-85% of the performance of a high end scope which, for a lot of people, will work for 100% of the shooting they do. I have a $600 scope on my AR15 and a $3300 scope on my precision AR10. Both do exactly the work they need to do and were chosen for their performance and not price.
I also have a 35 year old Leupold Vari-X III purchased for a custom rifle of the same age. I wouldn't trade that scope for any new scope because I'm so used to shooting the combination of gun and rifle scope. At this point, the performance of the pair are known at ranges from 100-600 yards just through use, in effect, they're a matched pair and I have no need to change anything.
Could I find a "better" scope today? You bet. Optics have improved immensely in the past 35 years with better coatings, designs and manufacturing techniques. But - the question is what would I gain? My answer is not much - I'm satisfied with the performance I have.
What you get in a truly high end optic is generally mechanical robustness paired with optics that provide better eye relief, color transmission, percentage of light transmission, contrast, and clarity. The image will appear more three dimensional and where the scope will really provide a performance difference is in low contrast, low light situations.
There can be other features like 80 MOA or MIL adjustments in the turrets, repeatable zero stop adjustments, custom reticles, front focal plane reticles, and lighted reticles - all of those kind of features raise the price of the optic and require additional mechanical design, engineering, and manufacturing steps to ensure they are as robust as the tube itself.
With scopes you can narrow down the requirements by very carefully evaluating the features you need to support the shooting tasks you have in mind.
Hunting has a totally different set of requirements than target shooting which is different than precision tactical rifle shooting, etc. Evaluating the use of the optic will lead to a range of choices which then have to be matched to the budget you have available for the scope.
My only advice on any type of optic is to buy the best you can afford when you purchase it from a known, quality manufacturer.
