Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account many ecological factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have about 11 parts which are located internally and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the best type of rifle glass is based around what type of shooting you plan to do.
Info About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to remain at the exact same dimensions in connection with the level of zoom being used. The final result is that the reticle dimensions adjust based upon the zoom employed to shoot over greater distances considering the reticle markings represent various increments which change with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular kinds of optics are beneficial for:
- Long distance styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who select a clearer optic picture without area taken up by the bigger FFP reticle
Magnification for Optics
The quantity of magnification a scope provides is identified 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 Single Power Lens Rifle Scopes
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the zoom 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.
About Variable Power Lens Rifle Glass
Variable power rifle scopes can be changed between magnification power levels. It will list the zoom degree in a format like 2-10×32. These numbers indicate the magnification of the scope could be adjusted between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Glass
Here are some recommended scope power settings and the ranges where they can be successfully used. Remember that high magnification scopes and optics will not be as efficient as lower magnification level optics and scopes due to the fact that too much magnification can be a detractor. The same idea relates to extended ranges where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Details on Scope Lens Covering
All contemporary rifle optic and scope lenses are layered. There are various types and qualities of lens finishings. Lens covering can be an important element of a rifle’s setup when thinking of high-end rifle optics and targeting equipment. The glass lenses are one of the most vital parts of the glass given that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface area and improves anti glare capabilities from excess sunrays and color recognition.
HD Versus ED Lenses
Some scope producers likewise use “HD” or high-definition lens coverings which use different methods, elements, polarizations, and chemicals to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Info on Single Finish Versus Multi-Coating
Various optic lenses can likewise have different coverings applied to them. All lenses typically 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 typically a protective and enhancing 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 optic. The quality of a single layered lens depends on the scope designer and how much money you spent for it. Both are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
About Hydrophobic Finish
Water on an optical lens doesn’t improve keeping a clear sight picture through a scope in any way. Many top of the line or premium optic 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 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.
Rifle Glass Mounting Alternatives
Mounting solutions for scopes come in a couple of options. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use manual levers which permit rifle operators to quickly mount and remove the optics.
Hex Key Rifle Glass Ring Mounts
Basic, clamp type mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use double separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are manufactured for long distance precision shooting. This form of scope mount is exceptional for rifle systems which need to have a long lasting, rock solid mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a dedicated scope setup on a long distance scouting or sniper competition firearm which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used to prevent the hex screw threads from backing out after they are installed securely in position. An example of these rings are the 30mm type from the Vortex Optics company. The set typically costs around $200 USD
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a similar design mount. These types of mounts come in handy for long guns which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles.
About Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Many scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Details on Rifle Optic Tube Gas Purging
Another component 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 currently occupied by the gas, the optic is less impacted by condition alterations and pressure variations from the external environment which could potentially 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.
