Info Scopes
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of separate natural aspects like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have about eleven parts which are found inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies in connection with the optic’s zoom. It simply means the reticle is situated behind or before the magnifying lens of the optic. Considering the most desired kind of rifle scope is dependent on what variety of shooting or hunting you intend on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who have an idea for their target “hold over” and “lead” ratios for their firearm
- Shooters who do not mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the zoom 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 reticle measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who prefer a clearer optic picture with less area taken up by the bigger FFP reticle
About Optic Zoom
The amount of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Rifle Glass
A single power rifle scope or optic comes with a zoom 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 optic can not fluctuate since it is set from the factory.
Variable Power Lens Optics
Variable power rifle scopes use variable power levels. The power change is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope power settings and the ranges where they could be successfully used. Highly magnified scopes will not be as beneficial as lower powered scopes considering that too much zoom can be a bad thing. The very same idea goes for longer ranges where the shooter needs sufficient power to see precisely where to properly aim the rifle.
Info on Lens Finishing
All top of the line rifle optic and scope lenses are covered. Lens covering is a crucial aspect of a shooting platform when buying high end rifle optics and scope equipment.
HD Versus ED Rifle Glass Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different techniques, aspects, chemicals, and polarizations to draw out separate 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.
Single Covering Versus Multi-Coating
Different optic lenses can likewise have different coatings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope maker and the amount you spent for it. Both are indications of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are coated or “multi” coated. This indicates the lens has multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can establish that a manufacturer is taking numerous steps to fight different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally doesn’t necessarily suggest the multi-coated lens is much better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle glass.
Details on Hydrophobic Covering
Water on an optical lens doesn’t help with keeping a clear sight picture through a scope in any way. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for 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 move off of the scope to keep a clear, water free sight picture.
Choices for Installing Rifle Optics on Long Guns
Mounting solutions for scopes are available in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release variations which use manual levers which enable rifle shooters to quickly install and remove the optics.
Hex Key Glass Ring Mounts
Standard, 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is great 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 Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be swapped in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts are useful and convenient for rifles which are hauled around a lot, to remove the glass from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day on the range and your highly-priced optic by triggering fogging and developing residue within the scope’s tube. The majority of scopes protect against humidity from entering the scope tube with a system of sealing O-rings which are water resistant. Generally, these optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness avoidance for standard use rifles, unless you intend on taking your rifle on a boat and are worried about the scope still working if it goes overboard and you can still find the gun.
Rifle Optic Gas Purging
Another component of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the optic is less affected by temp changes and pressure variations from the outside environment which could possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
