What You Need to Know About Rifle Optics
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a set of lenses within the scope. The scope’s positioning can be adapted for consideration of various environmental things like wind and elevation 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 with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle optics have about eleven parts which are arranged internally and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of an optic.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has establishes where the reticle or crosshair is located in relation to the scopes zoom. It literally means the reticle is behind or in front of the magnification lens of the scope. Looking for the most suitable type of rifle scope depends on what variety of hunting or shooting you anticipate doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) come with 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 measurement.
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who like a clearer optic sight picture without area used up by the larger sized FFP reticle
Rifle Optic Zoom
The level of scope zoom you need depends upon the type of shooting you plan to do. Practically every kind of rifle scope provides some level of magnification. The level of zoom a scope gives is identified by the size, density, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the opic. This denotes what the shooter is checking out through the scope is amplified times the power element of what can normally be seen by human eyes.
Fixed Power Lens Optic Facts
A single power rifle scope uses 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 adjust given that it is a fixed power scope.
Adjustable Power Lens Glass Facts
Variable power rifle scopes use variable power levels. The power change is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power Level and Ranges
Here are some recommended scope powers and the ranges where they could be effectively used. Highly magnified glass will not be as effective as lower magnification level optics due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same concept relates to longer ranges where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
Rifle Optic Lens Covering
All top of the line rifle glass lenses are layered. Lens finishing can be an essential element of a rifle when looking at high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens finishes which use various processes, polarizations, chemicals, and elements to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope company and how much money you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has numerous treatments applied to the surfaces. If a lens receives several treatments, it can prove that a producer is taking several actions to fight various environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens is much better than a single layered lens. Being “much better” depends upon the producer’s lens treatment innovation and the quality of glass used in building the rifle glass.
Info on Hydrophobic Finish
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Scope Mounting Choices
Mounting approaches for scopes come in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use throw levers which permit rifle shooters to rapidly mount and remove the glass.
Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount 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 are designed for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Several scopes can also be swapped out if they all use a similar design mount. These types of mounts come in 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 in between several rifles.
Info Around Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another component of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by temp shifts and pressure distinctions from the external environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
