Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target by making use of a set of lenses inside the scope. The scope’s positioning can be adapted to account for numerous environmental elements like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes and optics have around 11 parts which are arranged within and outside of the scope. These scope parts consist of the rifle scope’s body, lenses, elevation turrets, focus rings, and other parts. See all eleven parts of scopes.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has decides where the reticle or crosshair lies in relation to the scopes magnification. It literally suggests the reticle is behind or before the magnification lens of the scope. Choosing the most suitable kind of rifle optic depends upon what variety of hunting or shooting you plan on undertaking.
First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle ahead of the magnifying lens. This induces the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who recognize their target “hold over” as well as “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification 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 measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who would like a clearer optic picture without area taken up by the larger size FFP reticle
Magnification for Scopes
The level of scope zoom you need on your scope depends on the sort of shooting you would like to do. Pretty much every type of rifle glass offers some degree of zoom. The amount of magnification a scope supplies is identified by the dimension, thickness, and curves of the lenses within the rifle optic. The zoom of the scope is the “power” of the opic. This implies what the shooter is observing through the scope is magnified times the power element of what can usually be seen by human eyes.
About Single Power Lens Optics
A single power rifle scope or optic 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 scope can not adjust because it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power adjustment is handled by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some suggested scope power settings and the distances where they can be efficiently used. Consider that higher magnification optics and scopes will not be as practical as lower magnification level glass since excessive zoom can be a detractor. The same relates to extended ranges where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Lens Finish for Glass
All modern-day rifle glass lenses are covered. Lens finish is an essential element of a shooting system when buying high end rifle optics and scope setups.
HD Versus ED Rifle Scope Lens Coatings
Some glass manufacturers will also use “HD” or high-definition glass coatings which take advantage of various procedures, rare earth compounds, elements, and polarizations to extract a wide range of color ranges and viewable target visibility through lenses. This high-definition covering is normally used with more costly, high density glass which brings down light’s potential to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration is often obvious over objects with hard outlines as light hits the object from certain angles.
Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishings used to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much money you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has had several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can prove that a company is taking multiple steps to fight different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally doesn’t always suggest the multi-coated lens is much better than a single coated lens. Being “better” hinges on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle optic.
Hydrophobic Coating for Rifle Optics
Water on a scope lens does not support keeping a clear sight picture through an optic at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the surface area of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Glass Installation Alternatives
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also typically can be found in quick release variations which use manual levers which permit rifle operators to quickly install and dismount the optics.
Hex Key Rifle Glass Rings
Standard, 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope install is wonderful for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a similar style mount, multiple scopes can often be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These types of mounts come in convenient for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for sight systems which are utilized in between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It usually costs around $250 USD
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your expensive optic by triggering fogging and producing residue within the scope’s tube. Many scopes protect against humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Typically, these optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are concerned about the optic still working if it goes over the side and you can still recover the gun.
Rifle Scope Gas Purging
Another component of preventing the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the glass is less altered by temp shifts and pressure variations from the outdoor environment which could possibly permit 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.
