Optic Info
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by making use of a set of lenses within the scope. The scope’s positioning can be dialed in to account for numerous natural considerations like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes and optics have around eleven parts which are located within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has identifies where the reticle or crosshair is located in connection with the scopes zoom. It simply suggests the reticle is behind or in front of the magnification lens of the scope. Deciding upon the most desired form of rifle glass is based upon what type of shooting you anticipate doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are small
- Experienced shooters who understand their aim point “hold over” and “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) feature 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 reticle measurement.
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who would like a clearer optic sight picture with less room used up by the larger size FFP reticle
Zoom for Rifle Glass
The amount of zoom a scope supplies 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.
Info on Fixed Single Power Lens Scopes
A single power rifle scope will have 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 scope can not change because it is a set power scope.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes use enhanced power. The power change is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the ranges where they can be effectively used. Bear in mind that higher magnification glass will not be as practical as lower powered optics due to the fact that increased magnification can be a negative thing in certain situations. The very same idea applies to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Info on Lens Coverings
All modern-day rifle scope lenses are covered. Lens covering is a crucial aspect of a shooting system when looking at high end rifle optics and scope setups.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use various procedures, polarizations, chemicals, and components to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different scope lenses can even have various finishings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. This indicates the lens has several treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a producer is taking several actions to fight various natural factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not always indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends on the manufacturer’s lens treatment techniques and the quality of products used in constructing the rifle optic.
Anti-water Lens Finishes
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish which is water repellent.
Options for Installing Scopes on Long Guns
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release versions which use toss levers which permit rifle shooters to rapidly install and remove the glass.
Scope Mounts with Hex Key Rings
Normal, clamp style 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 made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is perfect 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 Glass Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Multiple scopes can also be swapped out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in handy for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for scopes which are employed between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another component of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less affected by condition alterations and pressure distinctions from the outside environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
