Optic Details
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification by employing a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of separate natural elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have around 11 parts which are found within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other elements. See all eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the optimal type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the level of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. As an example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who have an idea for their target “hold over” as well as “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick 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 of the shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic sight picture with less room taken up by the larger sized FFP reticle
Details on Scope Magnification
The quantity of magnification a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Fixed Power Lens Rifle Scopes
A single power rifle optic and scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not adjust since it is set from the factory.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power modification is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope power settings and the ranges where they can be effectively used. Consider that high magnification optics and scopes will not be as efficient as lower powered optics and scopes since excessive zoom can be a detractor. The very same idea relates to extended distances where the shooter needs enough power to see exactly where to best aim the rifle.
Info on Glass Lens Finishes
All modern rifle optic lenses are coated. There are different types and qualities of glass lens finishings. When shopping for luxury rifle optical systems, Lens covering can be an essential element of a rifle. The glass lenses are one of the most crucial parts of the glass due to the fact that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens exterior and also helps with anti glare capabilities from refracted daylight and color recognition.
ED Versus HD Glass
Some scope brands also use “HD” or high-definition lens finishes which use various procedures, chemicals, elements, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating for Rifle Scopes
Various optic lenses can likewise have various coverings used to them. All lenses normally have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope manufacturer and how much money you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has numerous treatments applied to them. If a lens receives multiple treatments, it can show that a manufacturer is taking several steps to fight various environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not always mean the multi-coated lens will perform much better than a single covered lens. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle glass.
Rifle Scope Lens Hydrophobic Covering
Water on an optic’s lens does not assist with keeping a clear sight picture through an optic in any way. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish. 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 water molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Optics on Firearms
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use throw levers which enable rifle operators to rapidly mount and remove the glass.
Hex Key Scope Rings
Normal, 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope install is excellent for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar style mount, multiple scopes can often be swapped on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely 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 preserving precision. These types of mounts come in handy for rifles which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are adopted in between numerous rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Optic 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. A lot of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Optic Gas Purging
Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the optic is less impacted by climate shifts and pressure differences from the outside environment which may possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
