Scope Details
Rifle scopes permit you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification by using a set of lenses within the scope. The scope’s positioning can be adapted to take into account varied environmental considerations like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have around eleven parts which are found internally and outside of the scope. These optic pieces include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane an optic has decides where the reticle or crosshair lies in regard to the optic’s magnification. It actually indicates the reticle is behind or in front of the magnification lens of the optic. Deciding on the best style of rifle optic depends upon what form of shooting or hunting you plan on undertaking.
About First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle in front of the zoom lens. This causes the reticle to increase in size based on 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 range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who like a clearer optic picture without area used up by the enlarged FFP reticle
About Rifle Scope Magnification
The quantity of zoom a scope supplies is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Scope Facts
A single power rifle optic and scope uses 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 scope can not fluctuate because it is set from the factory.
Adjustable Power Lens Glass
Variable power rifle scopes can be tweaked between magnified levels. The power modification is achieved by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some recommended scope powers and the distances where they may be effectively used. High power rifle scope glass will not be as efficient as lower magnification level glass since too much zoom can be a negative aspect depending on your shooting distance. The same concept goes for extended ranges where the shooter needs sufficient power to see where to properly aim the rifle at the target.
Info on Rifle Scope Lens Coverings
All contemporary rifle optic lenses are covered in special coatings. There are various types and qualities of lens coverings. When looking at high end rifle targeting setups, Lens coating can be an essential component of defining the rifle’s capability. The glass lenses are among the most essential parts of the glass given that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens surface and also improves anti glare from refracted sunlight and color perception.
HD Versus ED Lenses
Some scope suppliers even use “HD” or high-definition glass finishes that employ different processes, rare earth compounds, elements, and polarizations to extract separate colors and viewable target visibility through lenses. This high-definition covering is often used with higher density glass which decreases light’s potential to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible over things with hard edges and shapes as light hits the item from particular angles.
Single Finishing Versus Multi-Coating for Rifle Scopes
Different optic lenses can likewise have various coverings used to them. All lenses normally have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a manufacturer is taking numerous actions to fight different natural elements like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not always indicate the multi-coated lens will perform much better than a single covered lens. Being “better” is dependent on the manufacturer’s lens treatment techniques and the quality of components used in constructing the rifle optic.
Anti-water Finishing for Rifle Optics
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Installing Rifle Optics on Long Guns
Installing solutions for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use toss levers which allow rifle shooters to quickly install and remove the optics.
Hex Key Rifle Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is wonderful for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly 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 similar design mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day on the range and your costly optic by inducing fogging and creating residue inside of the scope’s tube. Many optics prevent wetness from going into the optical tube with a system of sealing O-rings which are waterproof. Usually, these scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content prevention for common use rifles, unless you anticipate taking your rifle on your motorboat and are worried about the optic still performing if it is submerged in water and you can still rescue the gun.
Gas Purged Rifle Scope Tubes
Another part of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less altered by temperature level changes and pressure differences from the external environment which may potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
