What You Need to Know About Rifle Scopes
Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of different natural considerations like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have about 11 parts which are located inside and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the optimal type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Optic Info
First focal plane scopes (FFP) include the reticle ahead of the magnification lens. This triggers the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their aim point “hold over” plus “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the magnifying lens. This triggers the reticle to stay at the same scale in relation to the level of zoom being used. The final result is that the reticle measurements adapt based upon the magnification applied to shoot over greater distances because the reticle markings represent distinct increments which differ with the zoom. 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. These styles of glass are beneficial for:
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who like a clearer optic sight picture without space used up by the larger size FFP reticle
Zoom for Rifle Optics
The measure of scope zoom you need on your optic is based on the type of shooting you would like to do. Just about every type of rifle scope provides some degree of magnification. The volume of zoom a scope delivers is identified by the dimension, thickness, and curves of the lenses within the rifle scope. The magnification of the optic is the “power” of the scope. This means what the shooter is aiming at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Scopes
A single power rifle optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change considering that it is a set power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will note the zoom amount in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be adjusted between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power manipulation is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope power settings and the ranges where they could be effectively used. Highly magnified rifle scope glass will not be as effective as lower magnification glass since too much magnification can be a bad thing. The very same idea applies to extended ranges where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Details on Glass Lens Finishes
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of lens finishes. Lens finish is a crucial aspect of a rifle when thinking of luxury rifle optics and scope equipment. The lenses are one of the most significant parts of the glass since they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface area and even improves anti glare capabilities from refracted direct sunlight and color exposure.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishings which use different procedures, polarizations, components, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
What to Know About Single Coating Versus Multi-Coating
Different scope lenses can also have different finishes applied to them. All lenses normally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered 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” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Rifle Glass Lens Anti-water Covering
Water on a scope lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Scope Mounting Options
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also typically are made in quick release versions which use toss levers which enable rifle shooters to rapidly install and dismount the scope.
Scope Mounts with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use a pair of independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are manufactured for long distance precision shooting. This form of scope mount is excellent for rifle systems which require a durable, hard use mount which will not shift despite how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a faithful optics system on a far away scouting or hard target interdiction firearm that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screw threads from backing out after they are mounted safely in position. An example of these rings are the 30mm type from the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Optic 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 even be swapped out if they all use a similar style mount. These types of mounts are convenient for long guns which are transported a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Info Around Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another part of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less impacted by temperature shifts and pressure distinctions from the external environment which may potentially enable 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.
