Windage and Elevation Adjustment
The Sightmark Core TX riflescopes are equipped with exposed, lockable windage and elevation turrets. 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 100yards. 1 MOA of movement would require 4 clicks.
Illumination Control
The Sightmark Core TX Riflescopes use an etched reticle. The reticle can be used without illumination and will appear black. The dial is marked with “G” for green or “R” for red followed by the brightness setting ranging from 0 (off) to 5. Setting 5 is best for bright, outdoor environments. Setting 1 is best for low light environments.
DCR Dual Caliber Reticle
This reticle is calibrated for .223 Rem. (55gr and 62gr) and .308 Win. (150gr and 155gr) and was designed for triple duty application: tactical, competition, and hunting. The design provides a fine .3 MOA central aiming crosshair at higher magnifications and holdovers for 300yd, 400yd, 500yd, 600yd and 700yd. The reticle was designed for a 100 yard zero. The calibers and grains ideal for this reticle shoot relatively flat, so the central aiming point of the reticle is used to shoot targets from 0 to 200 yards. For the most accurate precision at 200 yards, it is recommended to aim 3″ high on the target or 1.5 MOA.

Facts About Rifle Scopes

Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by making use of a set of lenses inside the scope. The scope’s alignment can be adapted to take into account varied environmental considerations 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 hit based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern rifle scopes and optics have around 11 parts which are located internally and outside of the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.

Rifle Glass Types

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the finest type of rifle scope is based around what type of shooting you plan on doing.

Info About First Focal Plane Optics

First focal plane scopes (FFP) feature the reticle before the magnification lens. This causes the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are beneficial for:

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where estimations are small
  • Experienced shooters who know their target “hold over” and “lead” relationships for their long guns
  • Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle

Second Focal Plane Scopes

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

  • Long distance kinds of shooting where shooters have extra time to make ballistic calculations
  • Shooting where most of the shots occur within shorter spaces and ranges
  • Shooters who want a clearer optic picture without area taken up by the larger size FFP reticle

About Glass Zoom

The quantity of scope zoom you need is based on the kind of shooting you want to do. Virtually every style of rifle glass delivers some degree of zoom. The level of magnification a scope delivers is established by the size, thickness, and curvatures of the lenses within the rifle scope. The zoom of the scope is the “power” of the scope. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.

Fixed Power Lens Scope Details

A single power rifle scope comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change because it is set from the factory.

Variable Power Lens Rifle Scopes

Variable power rifle scopes can be changed between magnification power levels. It will list the magnification level in a format such as 2-10×32. These numbers indicate the zoom of the scope can be changed between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power shift is achieved by applying the power ring component of the scope near the back of the scope by the eye bell piece.

The Power Level and Range Correlation of Rifle Optics

Here are some suggested scope powers and the distances where they can be successfully used. Highly magnified scopes will not be as efficient as lower magnification level glass due to the fact that too much zoom can be a bad thing. The same concept applies to longer ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.

Optic Lens Finish

All cutting-edge rifle glass lenses are covered. Lens finishing can be an important aspect of a rifle when buying high end rifle optics and scope equipment.

Info on Rifle Optic Lens Coatings – HD Versus ED

Some scope producers additionally use “HD” or high-def lens finishings that use various processes, rare earth compounds, aspects, and polarizations to draw out a wide range of color ranges and viewable definition through lenses. This high-def covering is normally used with more costly high density lens glass which brings down light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” implying 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 is often noticeable over things with hard edges and shapes as light hits the object from particular angles.

Single Rifle Optic Lens Finish Versus Multi-Coating

Different optic lenses can even have various finishings applied to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in lots of types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.

Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope manufacturer and how much you paid for it. The scope’s maker and cost are signs of the lens quality.

Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.

Hydrophobic Lens Finishing

Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic coating.

Rifle Scope Installation Options

Installing options for scopes come in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release versions which use manual levers which permit rifle shooters to rapidly mount and remove the optics.

Hex Key Optic Rings

Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is wonderful for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Optic Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly detach a scope and connect it to a different rifle. Multiple scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between numerous rifles.

Sealing and Gas Purging for Rifle Optic Tubes

Moisture inside your rifle optic can wreck a day on the range and your pricey optic by inducing fogging and making residue within the scope’s tube. Most scopes protect against moisture from getting in the scope tube with a system of sealing O-rings which are waterproof. Generally, these scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content avoidance for common use rifles, unless you intend on taking your rifle aboard watercrafts and are worried about the optic still functioning if it goes over the side and you can still retrieve the rifle.

Details on Glass Tube Gas Purging

Another component of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less affected by climate shifts and pressure differences from the external environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
