Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account varied ecological factors like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes have about 11 parts which are found inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other components. See all eleven parts of a rifle optical system.
About Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle glass is based on what type of shooting you plan to do.
About First Focal Plane Glass
First focal plane optics (FFP) feature the reticle ahead of the magnification lens. This causes the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified 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 types of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Scopes
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” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who want a clearer optic picture without space taken up by the bigger FFP reticle
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.
About Single Power Lens Rifle Optics
A single power rifle optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power optic.
Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power adjustment is performed by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some advised scope powers and the ranges where they may be effectively used. Keep in mind that high magnification optics will not be as efficient as lower powered glass because too much zoom can be a negative thing in certain situations. The very same idea applies to longer distances where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Lens Finishing for Rifle Scopes
All modern-day rifle optic and scope lenses are layered. Lens finishing is a vital aspect of a shooting platform when buying high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some rifle scope suppliers additionally use “HD” or high-def lense finishes that use various procedures, polarizations, chemicals, and components to draw out a wide range of color ranges and viewable definition through lenses. This high-definition coating is often used with higher density glass which reduces light’s potential to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard edges and shapes as light hits the item from particular angles.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can likewise have various finishings applied to them. All lenses typically have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less helpful 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 you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Rifle Optic Lens Covering
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finish which is water repellent.
Choices for Mounting Glass on Firearms
Mounting approaches for scopes come in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use manual levers which enable rifle shooters to rapidly mount and dismount the scope.
Hex Key Rifle Optic Rings
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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope mount is great for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. 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 keeping accuracy. These types of mounts come in convenient for rifles which are moved around a lot, to take off the glass from the rifle for protection, or for aiming systems which are employed between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
What to Know About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another part of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less impacted by temperature changes and pressure variations from the outdoor environment which could potentially allow 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.
