Rifle Scope Information
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of separate natural considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes and optics have about 11 parts which are found inside and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. See all eleven parts of an optic.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has establishes where the reticle or crosshair is located relative to the scopes zoom. It literally implies the reticle is situated behind or in front of the magnification lens of the scope. Looking for the most desired kind of rifle glass depends upon what type of shooting you plan on undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who know their target “hold over” and also “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane glass (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the same scale relative to the volume of zoom being used. The final result is that the reticle dimensions alter based upon the zoom employed to shoot over lengthier distances considering the reticle markings represent different increments which vary 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. These kinds of scopes are convenient for:
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who choose a clearer optic sight picture without room used up by the bigger FFP reticle
Magnification for Rifle Glass
The level of scope zoom you need on your glass depends on the type of shooting you want to do. Virtually every kind of rifle scope provides some amount of zoom. The level of magnification a scope delivers is identified by the dimension, thickness, and curvatures of the lenses within the rifle optic. The magnifying level of the optic is the “power” of the scope. This suggests what the shooter is observing through the scope is amplified times the power element of what can generally be seen by human eyes.
Info on Fixed Power Lens Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Glass Details
Variable power rifle scopes can be modified between magnified settings. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some advised scope power settings and the distances where they could be effectively used. High power rifle scope glass will not be as beneficial as lower powered rifle scope glass since too much zoom can be a bad thing. The very same idea relates to longer ranges where the shooter needs increased power to see exactly where to properly aim the rifle.
Glass Lens Covering
All top teir rifle scope lenses are covered. Lens finishing can be an important aspect of a shooting platform when buying high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope producers likewise use “HD” or high-definition lens finishes which use different methods, components, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Coating Versus Multi-Coating for Scopes
Various scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. 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 lots of kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less useful 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 makers also make it a point to specify if their optic lenses are layered or “multi” covered. This suggests the lens has multiple treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can establish that a company is taking numerous steps to combat different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily mean the multi-coated lens is better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment techniques and the quality of products used in building the rifle optic.
Anti-water Finish for Rifle Scopes
Water on an optic’s lens doesn’t improve maintaining a clear sight picture through a scope in any way. Lots of top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Rifle Optics on Firearms
Installing solutions for scopes are available in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use manual levers which allow rifle operators to rapidly mount and dismount the scope.
Hex Key Rifle Optic Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long range accuracy shooting. This type of scope mount is excellent 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 Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle glass can spoil a day of shooting and your pricey optic by resulting in fogging and developing residue inside of the scope’s tube. The majority of scopes protect against moisture from going into the scope tube with a system of sealing O-rings which are waterproof. Typically, these water-resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content prevention for basic use rifles, unless you intend on taking your rifle on your motorboat and are worried about the scope still working if it falls overboard and you can still find the firearm.
Info on Scope Tube Gas Purging
Another part of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less impacted by temperature level shifts and pressure differences from the outdoor environment which could possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
