What You Need to Know About Rifle Scopes
Rifle scopes allow you to specifically aim a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted to account for many environmental aspects like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes have around 11 parts which are found internally and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the finest type of rifle glass is based around what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who know their target “hold over” and also “lead” ratios for their long gun
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who would like a clearer optic picture without area used up by the larger sized FFP reticle
Zoom for Rifle Scopes
The quantity of magnification a scope supplies is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Scope Facts
A single power rifle optic uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power scope.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Scopes
Here are some recommended scope power settings and the ranges where they may be effectively used. Bear in mind that higher power glass will not be as efficient as lower powered optics and scopes because increased magnification can be a negative thing in certain situations. The very same idea relates to extended ranges where the shooter needs sufficient power to see where to best aim the rifle.
Details on Rifle Scope Lens Finishes
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of glass lens finishes. When thinking about high end rifle optical setups, Lens covering can be a critical aspect of defining the rifle’s capability. The lenses are among the most vital components of the optic since they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens exterior and also improves anti glare capabilities from excess direct sunlight and color discernibility.
HD Versus ED Lens Coatings
Some rifle glass producers will also use “HD” or high-def lense coverings which take advantage of different procedures, components, polarizations, and chemicals to draw out different color ranges and viewable target definition through lenses. This high-def coating is often used with more costly high density lens glass which decreases light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be visible around items with hard edges and outlines as light hits the object from certain angles.
Single Rifle Optic Lens Finishing Versus Multi-Coating
Various scope lenses can also have various finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a covering placed on it so that it will be optimally usable in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less beneficial 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 similarly 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 materials used in building the rifle scope.
Rifle Glass Lens Hydrophobic Finishing
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 optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Rifle Glass Installing Choices
Mounting approaches for scopes can be found in a few options. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release versions which use toss levers which permit rifle operators to quickly install and dismount the optics.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp-on design mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use double independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This form of scope mount is effective for rifles which are in need of a durable, unfailing mount which will not shift regardless of just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you want for a dedicated optics system on a reach out and touch someone scouting or hard target interdiction firearm which will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to protect against the hex screw threads from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. Several scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and practical for rifles which are transferred between vehicles a lot, to remove the optic from the rifle for protection, or for aiming systems which are utilized in between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less altered by climate shifts and pressure differences from the outside environment which may possibly allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
