What You Need to Know About Rifle Optics
Rifle scopes allow you to specifically 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 series of lenses within the scope. The scope’s alignment can be dialed in to account for various environmental aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle optics have about 11 parts which are arranged inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other parts. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has determines where the reticle or crosshair is located in regard to the scopes magnifying adjustments. It literally suggests the reticle is located behind or in front of the magnifying lens of the optic. Picking the most beneficial style of rifle glass is based upon what type of hunting or shooting you intend on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred 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 estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who want a clearer optic sight picture with less area used up by the bigger FFP reticle
Rifle Scope Zoom
The quantity of magnification a scope supplies is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Scopes
A single power rifle optic or scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate considering that it is a fixed power optic.
Info on Variable Power Lens Scopes
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification amount in a format like 2-10×32. These numbers suggest the zoom of the scope could be adjusted between 2x and 10x power. This always includes the powers in-between 2 and 10. The power manipulation is achieved by employing the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power and Range of Glass
Here are some recommended scope power settings and the ranges where they can be effectively used. Consider that high power scopes will not be as effective as lower magnification level optics since too much magnification can be a negative thing in certain situations. The exact same concept applies to extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle.
Rifle Scope Lens Finish
All state-of-the-art rifle optic and scope lenses are layered. Lens covering is a significant aspect of a shooting system when looking into high end rifle optics and scope equipment.
ED Versus HD Scopes
Some rifle glass manufacturers additionally use “HD” or high-def glass finishings which take advantage of various processes, polarizations, chemicals, and aspects to enhance different colors and viewable definition through lenses. This HD covering is often used with increased density lens glass which lowers light’s chance to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over things with defined shapes as light hits the item from certain angles.
Details on Single Coating Versus Multi-Coating
Different optic lenses can also have different coverings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in lots of kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
About Hydrophobic Coating
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic covering.
Glass Installation Options
Installing solutions for scopes are available in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use toss levers which allow rifle operators to rapidly mount and dismount the optics.
Hex Key Scope Ring Mounts
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope mount is great for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Scope Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a similar style mount, multiple scopes can often be swapped in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These kinds of mounts come in beneficial for shooting platforms which are hauled around a lot, to remove the glass from the rifle for protection, or for optics which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and generating residue inside of the scope’s tube. A lot of scopes protect against wetness from getting in the optical tube with a system of sealing O-rings which are waterproof. Generally, these optics can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness prevention for common use rifles, unless you plan on taking your rifle boating and are worried about the scope still functioning if it goes overboard and you can still rescue the gun.
Gas Purged Rifle Optic Tubes
Another component of preventing the buildup of wetness within 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 influenced by temperature shifts and pressure differences from the outdoor environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
