What You Need to Know About Rifle Optics
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a set of lenses within the scope. The scope’s alignment can be adjusted to take into account different ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle optics have about 11 parts which are arranged within and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage turrets, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has decides where the reticle or crosshair is located in regard to the optic’s magnification. It actually indicates the reticle is located behind or before the magnifying lens of the scope. Deciding upon the most desired form of rifle scope depends upon what style of hunting or shooting you plan on undertaking.
Info About First Focal Plane Glass
First focal plane optics (FFP) feature the reticle before the zoom lens. This induces the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who understand their target “hold over” as well as “lead” ratios for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who prefer a clearer optic picture with less space used up by the enlarged FFP reticle
Ins and Outs of Scope Zoom
The quantity of scope zoom you need on your glass depends on the sort of shooting you like to do. Almost every style of rifle glass delivers some level of zoom. The volume of magnification a scope supplies is established by the diameter, thickness, and curvatures of the lens glass inside of the rifle optic. The zoom of the optic is the “power” of the glass. This implies what the shooter is looking at through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Fixed Power Lens Rifle Optic Details
A single power rifle scope and optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a fixed power scope.
Info on Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. It will note the zoom amount in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power manipulation is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope powers and the ranges where they may be effectively used. Always remember that higher magnification glass will not be as effective as lower magnification level optics and scopes because too much magnification can be a negative thing in certain situations. The same concept applies to longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Rifle Glass Lens Finishing
All modern rifle scope lenses are coated. There are various types and qualities of glass coatings. When researching high end rifle scope units, Lens coating can be a vital element of defining the capability of the rifle. The lenses are among the most significant components of the scope considering they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses shields the lens surface area and even helps with anti glare from refracted sunrays and color exposure.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishings which use different processes, polarizations, chemicals, and aspects to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Glass Lens Single Coating Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. 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 needs to have a covering placed on it so that it will be optimally functional in many types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope company and the amount you spent on it. Both are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finish.
Options for Mounting Scopes on Long Guns
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use toss levers which permit rifle operators to rapidly mount and dismount the scope.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is wonderful for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, several scopes can often be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts come in beneficial for rifles which are transferred a lot, to remove the scope from the rifle for protection, or for aiming systems which are adopted in between a number of rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Info Around Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by bringing about fogging and creating 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 waterproof.
Gas Purged Scope Tubes
Another part of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the optic is less impacted by condition alterations and pressure differences from the outdoor environment which may possibly permit water vapor to seep 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.
