Optic Facts
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be dialed in to take into account various natural aspects like wind and elevation increases or decreases to account 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 through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have around 11 parts which are arranged internally and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other parts. See all eleven parts of a scope.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located relative to the scopes magnification. It simply suggests the reticle is located behind or in front of the magnifying lens of the optic. Selecting the most desired form of rifle glass is dependent on what style of shooting you plan on doing.
Info About First Focal Plane Optics
First focal plane glass (FFP) feature the reticle before the magnification lens. This causes the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who know their aim point “hold over” and also “lead” relationships for their rifles
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This causes the reticle to remain at the exact same size in connection with the amount of magnification being used. The result is that the reticle dimensions adapt based on the magnification applied to shoot over lengthier distances due to the fact that the reticle markings represent different increments which fluctuate with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular styles of scopes work for:
- Long distance kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within much shorter distances and ranges
- Shooters who would like a clearer optic picture with less space taken up by the larger size FFP reticle
Optic Zoom
The quantity of zoom a scope offers is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass
A single power rifle 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 magnification of this type of optic can not adjust because it is fixed.
Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power modification is achieved by the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some advised scope powers and the ranges where they may be efficiently used. High power glass will not be as effective as lower powered optics given that too much magnification can be a negative aspect depending on your shooting distance. The very same idea relates to longer ranges where the shooter needs adequate power to see where to best aim the rifle.
Rifle Scope Lens Finish
All modern rifle optic and scope lenses are coated. There are various types and qualities of glass finishes. Lens finish is a crucial aspect of a rifle when looking into high-end rifle optics and targeting equipment. The glass lenses are one of the most essential pieces of the glass because they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens exterior as well as assists with anti glare capabilities from refracted natural light and color visibility.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use different processes, chemicals, polarizations, and aspects to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
About Single Finish Versus Multi-Coating
Various optic lenses can likewise have various coverings applied to them. All lenses generally 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 offer protection to the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Coating
Water on an optical lens doesn’t assist with retaining a clear sight picture through an optic in any way. Numerous top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the surface area of the Steiner scope lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Rifle Optic Mounting Alternatives
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the scope.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate 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 fine for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can spoil a day on the range and your pricey optic by triggering fogging and producing residue inside of the scope tube. Many scopes prevent humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Normally, these water resistant optics can be immersed 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 avoidance for standard use rifles, unless you anticipate taking your rifle aboard watercrafts and are worried about the optic still working if it is submerged in water and you can still rescue the rifle.
Rifle Optic Gas Purging
Another part of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the scope is less altered by temperature changes and pressure variations from the outdoor environment which may possibly permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
