What You Need to Know About Scopes
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be dialed in to take into account various environmental things like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have about 11 parts which are located internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has determines where the reticle or crosshair is located in relation to the optic’s zoom. It actually indicates the reticle is behind or ahead of the magnification lens of the optic. Selecting the most reliable form of rifle scope is based on what type of shooting you plan on doing.
About First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle ahead of the zoom lens. This causes the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who understand their aim point “hold over” and also “lead” correlations for their firearms
- Shooters who do not mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who would like a clearer optic picture without area taken up by the bigger FFP reticle
Magnification for Scopes
The quantity of zoom a scope offers is figured out by the diameter, density, 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 Details
A single power rifle optic or scope uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate since it is a fixed power scope.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will list the zoom degree in a configuration like 2-10×32. These numbers mean the zoom of the scope can be adjusted in between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power shift is accomplished by working with the power ring part of the scope near the rear of the scope by the eye bell piece.
Rifle Optic Power Level and Range Correlation
Here are some suggested scope powers and the distances where they may be efficiently used. Highly magnified optics will not be as efficient as lower magnification level optics given that too much zoom can be a bad thing. The same idea applies to longer distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Lens Finishing for Rifle Optics
All modern rifle scope lenses are coated. There are various types and qualities of coatings. When looking at high end rifle optics and scope units, Lens coating can be a very important element of a rifle. The glass lenses are among the most important components of the glass because they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses protects the lens exterior and helps with anti glare capabilities from excess natural light and color recognition.
Details on Rifle Glass Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and elements to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different finishings applied to them. All lenses normally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing 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 upon the scope maker and just how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This indicates the lens has numerous treatments applied to the surfaces. If a lens receives several treatments, it can prove that a company is taking multiple steps to fight various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally doesn’t always mean the multi-coated lens will perform better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of components used in building the rifle optic.
Hydrophobic Covering for Glass
Water on a scope lens does not improve retaining a clear sight picture through a scope in any way. Numerous top of the line or premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Glass on Long Guns
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use throw levers which allow rifle operators to rapidly mount and remove the glass.
Hex Key Rifle Optic Rings
Basic, clamp design mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on rifles. These kinds of scope mounts use two independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This type of scope mount is exceptional for rifle systems which need a durable, unfailing mount which will not move no matter how much the scope is moved about or abuse the rifle takes. These are the type of mounts you really want to have for a specialized scope setup on a long distance hunting or competitors long gun that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from wiggling out after they are installed securely in position. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. Multiple scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These kinds of mounts come in handy for rifles which are transported a lot, to remove the glass from the rifle for protection, or for optics which are employed in between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another element of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less altered by temperature changes and pressure variations from the external environment which could potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
