Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by utilizing a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of numerous environmental things like wind speed and elevation to make up for bullet drop.
The scope’s function is to 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 intended point of impact. The majority of modern-day rifle scopes have around 11 parts which are found internally and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the best type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Optics
First focal plane optics (FFP) include the reticle before the magnification lens. This induces the reticle to increase in size based upon the amount of zoom being used. The result 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 any “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are low
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This causes the reticle to remain at the exact same size in relation to the level of zoom being used. The result is that the reticle measurements adapt based upon the zoom used to shoot over greater distances considering the reticle measurements represent various increments which fluctuate with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These kinds of optics are handy for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who desire a clearer optic sight picture without room used up by the enlarged FFP reticle
Magnification for Glass
The level of scope magnification you require depends upon the type of shooting you want to do. Nearly every type of rifle optic supplies some degree of magnification. The volume of magnification a scope delivers is determined by the diameter, thickness, and curves of the lenses within the rifle scope. The magnifying level of the scope is the “power” of the scope. This implies what the shooter is looking at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
About Fixed Single Power Lens Rifle Glass
A single power rifle scope comes with a zoom number designator like 4×32. This means 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 because it is set from the factory.
Info About Variable Power Lens Rifle Optics
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification amount in a format such as 2-10×32. These numbers suggest the magnification of the scope could be adjusted between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power manipulation is accomplished by working with the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope power settings and the ranges where they can be effectively used. High power optics will not be as efficient as lower magnification level scopes because too much zoom can be a bad thing. The exact same idea relates to extended ranges where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Rifle Glass Lens Finishing
All modern-day rifle scope lenses are coated. There are various types and qualities of finishings. Lens coating can be a crucial aspect of a rifle’s setup when contemplating high-end rifle optics and scope systems. The glass lenses are among the most crucial pieces of the scope given that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens surface and even improves anti glare capabilities from refracted light and color exposure.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and elements to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Scopes
Different optic lenses can likewise have different finishes used to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
This lens treatment can safeguard 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 manufacturer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a company is taking multiple actions to combat different natural factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not always mean the multi-coated lens is better than a single coated lens. Being “better” hinges on the manufacturer’s lens treatment techniques and the quality of materials used in building the rifle glass.
Info on Hydrophobic Coating
Water on a lens does not improve retaining a clear sight picture through an optic in any way. Lots of top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Options for Installing Optics on Long Guns
Mounting options for scopes come in a few options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically come in quick release variations which use toss levers which allow rifle shooters to rapidly mount and dismount the scope.
Hex Key Rifle Scope Ring Mounting Solutions
Basic, clamp-on design mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use double individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This form of scope mount is exceptional for rifle systems which require a durable, rock solid mount which will not move despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you want for a devoted scope setup on a reach out and touch someone scouting or tournament rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to stop the hex screws from wiggling out after they are mounted securely in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. Many scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another component of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less impacted by temp alterations and pressure differences from the outside environment which could possibly allow 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 look for.
