What You Need to Know About Scopes
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom using a set of lenses inside the scope. The scope’s alignment can be adapted for the consideration of separate environmental factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around 11 parts which are found within and outside of the optic. These optic pieces include the rifle scope’s body, lenses, windage turrets, focus rings, and other components. Learn about the eleven parts of scopes.
Rifle Optic Styles
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 regard to the scopes magnification. It actually means the reticle is situated behind or ahead of the magnification lens of the optic. Selecting the most ideal type of rifle glass depends upon what form of shooting or hunting you anticipate undertaking.
About First Focal Plane Scopes
First focal plane optics (FFP) come with the reticle ahead of the zoom lens. This triggers the reticle to increase in size based upon the level of zoom being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who have an idea for their target “hold over” and “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) feature the reticle behind 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 measurement.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture without room taken up by the enlarged FFP reticle
Magnification for Scopes
The quantity of zoom 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.
Fixed Single Power Lens Glass
A single power rifle optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change since it is set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification increments. These types of scopes will note the zoom level in a format like 2-10×32. These numbers indicate the magnification of the scope could be set between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power manipulation is achieved by operating the power ring part of the scope near the back of the scope by the eye bell piece.
The Power and Range of Rifle Scopes
Here are some suggested scope powers and the ranges where they can be successfully used. Always remember that higher power optics will not be as effective as lower powered scope and optics since increased zoom can be a detractor. The same concept applies to extended ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Info on Lens Covering
All current rifle scope lenses are coated. Lens coating is a vital element of a shooting system when looking into high end rifle optics and scope equipment.
Info on Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coatings which use different procedures, chemicals, polarizations, and elements to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can likewise have various coatings used to them. All lenses usually have at least some type of treatment or finish used to them prior to 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 manufacturer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can indicate that a maker is taking several steps to combat different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This additionally does not necessarily suggest the multi-coated lens will perform better than a single layered lens. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
About Hydrophobic Coating
Water on an optic’s lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Glass on Long Guns
Mounting options for scopes come in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use throw levers which enable rifle operators to quickly install and remove the glass.
Hex Key Scope Rings
Basic, clamp type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This type of scope mount is good for rifle systems which need a long lasting, hard use mount which will not change despite just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful optics setup on a reach out and touch someone hunting or hard target interdiction long gun that will hardly ever need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from backing out after they are mounted securely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another component of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the optic is less influenced by temp alterations and pressure differences from the external environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
