Rifle scopes enable you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of different natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have around 11 parts which are arranged inside and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane a scope has decides where the reticle or crosshair lies in regard to the optic’s magnifying adjustments. It literally indicates the reticle is behind or ahead of the magnification lens of the scope. Considering the most suitable style of rifle optic is dependent on what type of hunting or shooting you plan on undertaking.
Info on First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who select a clearer optic sight picture without room used up by the larger sized FFP reticle
Details on Rifle Glass Zoom
The extent of scope magnification you need is based on the form of shooting you want to do. Almost every style of rifle glass gives some amount of magnification. The amount of zoom a scope delivers is established by the size, density, and curvatures of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the opic. This indicates what the shooter is checking out through the scope is magnified times the power aspect of what can generally be seen by human eyes.
Single Power Lens Scope Facts
A single power rifle scope and optic comes with a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change given that it is set from the factory.
Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power modification is accomplished 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 recommended scope power levels and the ranges where they could be efficiently used. Remember that high power optics and scopes will not be as effective as lower powered scope and optics due to the fact that too much magnification can be a detractor. The exact same idea relates to extended distances where the shooter needs to have enough power to see precisely where to properly aim the rifle at the target.
Info on Rifle Scope Lens Coatings
All modern rifle scope lenses are layered. Lens finish can be a crucial element of a rifle when considering high end rifle optics and scope equipment.
Info on Glass Lens Coatings – HD Versus ED
Some rifle scope makers even use “HD” or high-definition lens coatings that employ various procedures, components, chemical substances, and polarizations to extract numerous color ranges and viewable definition through lenses. This HD finishing is commonly used with higher density lens glass which reduces light’s ability to refract through the lens glass. Some scope brands use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be visible over things with hard edges and shapes as light hits the object from specific angles.
Single Finish Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses normally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely 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 sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope company and how much you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in building the rifle scope.
Info on Anti-water Finishing
Water on an optical lens does not improve maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Optic Mounting Alternatives
Installing options for scopes can be found in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also normally are made in quick release versions which use toss levers which allow rifle operators to rapidly install and dismount the scope.
Hex Key Rifle Scope Ring Mounts
Normal, 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These types of mounts come in handy for rifles which are transported a lot, to remove the glass from the rifle for protection, or for optics which are employed in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Scope Tubes
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less affected by temperature changes and pressure variations from the outside environment which may possibly enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
