Rifle Optic Details
Rifle scopes permit you to exactly aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification by utilizing a set of lenses within the scope. The scope’s alignment can be adjusted to account for various environmental things like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have around 11 parts which are arranged within and outside of the optic. These optic pieces include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other elements. See all eleven parts of an optic.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle optic is based on what type of shooting you plan to do.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the identical tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and “lead” equations for their rifles
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. This induces the reticle to remain at the exact same dimensions in relation to the level of zoom being used. The end result is that the reticle measurements change based upon the zoom employed to shoot over lengthier ranges considering the reticle markings represent distinct increments which fluctuate with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of scopes work for:
- Far away types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without space taken up by the enlarged FFP reticle
About Rifle Scope Magnification
The amount of zoom a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Power Lens Scopes
A single power rifle optic will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a fixed power optic.
Adjustable Power Lens Glass Info
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some advised scope powers and the distances where they may be effectively used. Bear in mind that high magnification optics will not be as practical as lower magnification level scopes due to the fact that increased magnification can be a detractor. The very same idea goes for extended distances where the shooter needs to have enough power to see where to best aim the rifle at the target.
Lens Coating for Scopes
All contemporary rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass finishings. Lens finish is a crucial aspect of a rifle’s setup when considering high-end rifle optics and scope units. The lenses are among the most essential pieces of the optic as they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and assists with anti glare capabilities from excess natural light and color profiles.
ED Versus HD Rifle Scopes
Some glass suppliers also use “HD” or high-def lens coatings that use various processes, polarizations, rare earth compounds, and elements to draw out a wide range of colors and viewable definition through lenses. This HD finishing is typically used with increased density glass which lowers light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often noticeable around things with hard outlines as light hits the object from specific angles.
Details on Single Finish Versus Multi-Coating
Different optic lenses can likewise have different coatings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in building the rifle scope.
Hydrophobic Scope Lens Coating
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Mounting Rifle Glass on Long Guns
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally can be found in quick release versions which use toss levers which allow rifle shooters to rapidly install and remove the optics.
Hex Key Glass Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between multiple rifles or are situationally focused.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day on the range and your expensive optic by resulting in fogging and developing residue inside of the scope’s tube. A lot of optics prevent humidity from getting in the scope tube with a system of sealing O-rings which are waterproof. Normally, these scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content prevention for standard use rifles, unless you plan on taking your rifle aboard watercrafts and are concerned about the scope still functioning if it falls overboard and you can still retrieve the gun.
Rifle Scope Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less impacted by condition shifts and pressure distinctions from the outside environment which might possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
