Rifle scopes enable you to precisely align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s alignment can be adapted to account for different environmental aspects like wind and elevation increases to account 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. The majority of modern rifle optics have about eleven parts which are found inside and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. Learn about the eleven parts of scopes.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the finest type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Glass Info
First focal plane optics (FFP) include the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are small
- Experienced shooters who have an idea for their aim point “hold over” and “lead” ratios for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room 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. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who would like a clearer optic picture without area used up by the larger size FFP reticle
The amount of magnification a scope supplies is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Optic Details
A single power rifle optic or 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 zoom of this type of optic can not adjust since it is a fixed power scope.
About Variable Power Lens Glass
Variable power rifle scopes use variable power levels. The power modification is accomplished by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Optics
Here are some recommended scope power settings and the ranges where they can be effectively used. Bear in mind that high magnification scopes and optics will not be as efficient as lower magnification level scope and optics since increased magnification can be a negative thing in certain situations. The exact same concept goes for longer ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Finishing for Scopes
All contemporary rifle scope lenses are layered. There are various types and qualities of finishings. Lens coating is an important element of a rifle when looking into high-end rifle optics and targeting units. The lenses are one of the most significant components of the optic as they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens exterior as well as helps with anti glare from refracted sunrays and color discernibility.
HD Versus ED Lenses
Some rifle scope producers additionally use “HD” or high-definition lens coverings which apply various processes, aspects, chemicals, and polarizations to draw out numerous color ranges and viewable definition through the lens. This HD finish is frequently used with increased density glass which drops light’s chance to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often noticeable around items with well defined shapes as light hits the object from specific angles.
Single Rifle Scope Lens Finishing Versus Multi-Coating
Various optic lenses can also have different finishings used to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope designer and how much money you paid for it. Both the manufacturer and amount are indications of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This means the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can prove that a maker is taking multiple steps to fight different natural aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This also doesn’t always imply the multi-coated lens is much better than a single covered lens. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle glass.
Hydrophobic Optic Lens Coating
Water on an optical lens does not help with maintaining a clear sight picture through a scope in any way. Lots of top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Choices for Installing Optics on Long Guns
Installing options for scopes come in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically can be found in quick release variations which use manual levers which enable rifle operators to rapidly install and remove the glass.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp-on style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This type of scope mount is effective for rifle systems which are in need of a durable, rock solid mount which will not change regardless of just how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a devoted optics system on a far away hunting or competitors long gun that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from backing out after they are mounted safely in place. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a comparable design mount, several scopes can often be switched on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These types of mounts come in handy for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for optics which are employed between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Details on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day on the range and your costly optic by resulting in fogging and making residue inside of the scope’s tube. Most scopes protect against moisture from getting in the scope tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are worried about the optic still functioning if it goes overboard and you can still retrieve the rifle.
Info on Rifle Scope Tube Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the scope is less altered by temp changes and pressure distinctions from the outdoor environment which could potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
