Optic Facts
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses inside the scope. The scope’s positioning can be adapted to take into account many natural elements like wind and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle scopes have about eleven parts which are located inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has determines where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It actually means the reticle is located behind or ahead of the magnifying lens of the scope. Picking out the most suitable type of rifle glass depends upon what style of shooting or hunting you anticipate doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who know their target “hold over” as well as “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who choose a clearer optic picture without space taken up by the larger sized FFP reticle
Rifle Optic Zoom
The amount of magnification a scope provides is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Info
A single power rifle optic and scope will have 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 scope can not fluctuate since it is set from the factory.
Variable Power Lens Optic Details
Variable power rifle scopes use enhanced power. The power modification is handled using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Scopes
Here are some suggested scope powers and the ranges where they may be efficiently used. Consider that high magnification optics and scopes will not be as effective as lower magnification level scopes since increased magnification can be a negative thing in certain situations. The exact same idea goes for longer ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Lens Finishing for Optics
All top teir rifle optic and scope lenses are coated. Lens coating can be a vital element of a shooting platform when looking at high end rifle optics and scope setups.
About Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishings which use different procedures, aspects, chemicals, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have different finishings used to them. All lenses typically have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single coated 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 decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope developer and the amount you spent for it. Both are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Scope Lens Anti-water Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating.
Optic Installation Choices
Mounting solutions for scopes can be found in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally come in quick release versions which use throw levers which allow rifle operators to rapidly install and remove the glass.
Glass Mounts with Hex Key Rings
Standard, clamp-on type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use double independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This type of scope mount is excellent for rifles which are in need of a durable, hard use mount which will not move regardless of just how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a specialized optics system on a far away hunting or competition long gun that will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screws from backing out after they are mounted safely in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. If they all use a similar style mount, several scopes can often be switched out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping precision. These types of mounts come in handy for shooting platforms which are carried a lot, to take off the optic from the rifle for protection, or for aiming systems which are utilized between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another component of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less affected by climate changes and pressure distinctions from the outside environment which could potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
