Diopter Adjustment
The Sightmark Core HX riflescope’s eyepiece is designed to rotate to adjust for diopter. The diopter is the measurement of the eye’s curvature. People’s eyes are all curved differently. If the reticle does not appear clear, crisp, nor sharp, rotate the eyepiece until the reticle becomes clear and sharp. This adjustment should stay the same unless the riflescope’s operator changes.
Windage and Elevation Adjustment
The Sightmark Core HX riflescopes come with pre-installed turret caps to protect the windage and elevation adjustments from impacts. The Sightmark Core HX riflescopes have finger adjustable elevation and windage adjustments with audible clicks. Each scope has it’s MOA click value marked on the adjustment. For example, a MOA click means each click moves the point of impact .25″ at 100 yards. 1 MOA of movement would require 4 clicks

Facts About Rifle Optics

Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by using a set of lenses inside the scope. The scope’s alignment can be dialed in to account for varied ecological aspects like wind speed and elevation increases to account for bullet drop.

The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle optics have about eleven parts which are arranged within and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. See all eleven parts of a rifle optical system.

The Varieties of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has decides where the reticle or crosshair is located relative to the optic’s magnifying adjustments. It simply indicates the reticle is situated behind or in front of the magnification lens of the optic. Picking the best sort of rifle scope depends upon what kind of hunting or shooting you anticipate doing.

First Focal Plane Glass

Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are helpful for:

  • Quick acquisition, long distance types of shooting
  • Shooting situations where calculations are small
  • Experienced shooters who know their target “hold over” plus “lead” equations for their rifles
  • Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle

Second Focal Plane Scope Details

Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.

  • Far away kinds of shooting where shooters have extra time to make ballistic estimations
  • Shooting where most shots take place within much shorter spaces and ranges
  • Shooters who prefer a clearer optic picture with less room used up by the larger sized FFP reticle

Optic Zoom

The quantity of scope zoom you need depends on the type of shooting you would like to do. Pretty much every type of rifle scope gives some amount of magnification. The level of zoom a scope offers is established by the diameter, density, and curvatures of the lens glass within the rifle scope. The zoom of the scope is the “power” of the glass. This implies what the shooter is observing through the scope is amplified times the power element of what can generally be seen by human eyes.

About Fixed Single Power Lens Rifle Scopes

A single power rifle scope uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate given that it is fixed.

Info About Adjustable Power Lens Rifle Scopes

Variable power rifle scopes can be modified between magnified settings. The power change is achieved using the power ring part of the scope near the rear of the scope by the eye bell.

Power Levels and Range

Here are some recommended scope powers and the distances where they could be efficiently used. Highly magnified glass will not be as beneficial as lower magnification level glass considering that too much zoom can be a bad thing. The same concept applies to extended distances where the shooter needs to have enough power to see precisely where to properly aim the rifle.

Rifle Glass Lens Coating

All present day rifle scope and optic lenses are coated. Lens finish is a vital aspect of a shooting platform when looking at high end rifle optics and scope systems.

HD Versus ED Glass Lens Coatings

Some optic suppliers also use “HD” or high-def lense finishings that apply different processes, elements, chemical substances, and polarizations to extract separate colors and viewable target visibility through the lens. This high-def covering is frequently used with increased density glass which drops light’s potential to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be obvious around items with hard edges and outlines as light hits the object from various angles.

Single Finish Versus Multi-Coating

Various optic lenses can likewise have various finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.

This lens treatment can protect the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.

Some scope makers also make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a maker is taking several actions to fight various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not always imply the multi-coated lens will perform much better than a single covered lens. Being “much better” depends on the producer’s lens treatment techniques and the quality of materials used in developing the rifle optic.

Anti-water Lens Coatings

Water on a scope lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.

Options for Installing Rifle Scopes on Firearms

Installing options for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release variations which use manual levers which permit rifle shooters to quickly install and dismount the optics.

Optic Mounts with Hex Key Rings

Basic, clamp design mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the optic, and are normally made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is effective for rifles which require a durable, rock solid mount which will not change regardless of just how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a devoted scope system on a long distance hunting or competitors long gun which will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to protect against the hex screw threads from wiggling out after they are mounted firmly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD

Glass Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. Several scopes can also be switched out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining the original sighting settings. These types of mounts are useful and practical for rifles which are moved a lot, to remove the glass from the rifle for protection, or for sight systems which are chosen for use in between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD

Scope Tube Sealing and Gas Purging

Wetness inside your rifle optic can destroy a day on the range and your pricey optic by resulting in fogging and making residue within the scope’s tube. Most optics prevent moisture from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these water resistant optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough humidity avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are worried about the optic still performing if it falls overboard and you can still salvage the firearm.

Rifle Scope Gas Purging

Another element of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less impacted by climate alterations and pressure differences from the external environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
