What You Need to Know About Scopes
Rifle scopes enable you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous environmental factors like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly 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 point of impact. A lot of modern rifle scopes have around eleven parts which are arranged inside and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. See all eleven parts of an optic.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has determines where the reticle or crosshair lies relative to the scopes magnification. It simply implies the reticle is situated behind or before the magnification lens of the optic. Deciding on the most effective type of rifle optic depends on what kind of hunting or shooting you anticipate doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the magnifying 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 magnified range. For example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” relationships for their rifles
- Shooters who don’t mind the reticle is enlarged and uses 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 measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who desire a clearer optic sight picture with less space used up by the larger size FFP reticle
Zoom for Rifle Optics
The amount of magnification a scope supplies is determined 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 on Fixed Power Lens Optics
A single power rifle optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change because it is a fixed power optic.
Variable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification power levels. It will note the zoom amount in a configuration like 2-10×32. These numbers mean the magnification of the scope can be set between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power shift is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Rifle Scopes
Here are some recommended scope powers and the ranges where they may be successfully used. Remember that higher magnification optics will not be as practical as lower powered glass because excessive magnification can be a bad thing. The very same idea goes for longer ranges where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.
Info on Lens Finishes
All modern-day rifle scope and optic lenses are coated. Lens finishing is an essential element of a rifle when considering high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coverings which use various methods, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Rifle Glass Lens Single Coating Versus Multi-Coating
Various optic lenses can also have various finishes used to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering 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 on the scope producer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Finishing
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 military grade optic makers will coat their lenses with a hydrophobic or hydrophilic covering which is water repellent.
Rifle Optic Installation Options
Installing approaches for scopes are available in a couple of 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 kinds of mounts also normally can be found in quick release versions which use throw levers which enable rifle operators to rapidly mount and dismount the scopes.
Rifle Glass Mounts with Hex Key Rings
Standard, 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope mount is wonderful for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a comparable design mount, several scopes can often be swapped in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These kinds of mounts are useful and practical for rifles which are hauled around a lot, to remove the optic from the rifle for protection, or for optics which are adopted between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day of shooting and your highly-priced optic by triggering fogging and generating residue inside of the scope tube. Many scopes prevent wetness from going into the optical tube with a system of sealing O-rings which are water resistant. Usually, these optics can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the scope still performing if it goes over the side and you can still recover the firearm.
Gas Purged Rifle Optic Tubes
Another element of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less altered by climate shifts and pressure distinctions from the external environment which could possibly enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
