Rifle Optic Facts
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account separate ecological considerations like wind and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have around eleven parts which are found internally and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the perfect type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Optic Details
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their weapon
- Shooters who do not mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who like a clearer optic picture with less area taken up by the bigger FFP reticle
Zoom for Rifle Glass
The amount of scope zoom you need depends on the kind of shooting you would like to do. Practically every kind of rifle scope gives some degree of zoom. The quantity of zoom a scope provides is identified by the size, density, and curvatures of the lenses within the rifle optic. The magnifying level of the scope is the “power” of the glass. This denotes what the shooter is observing through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Rifle Scope Facts
A single power rifle optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a fixed power optic.
Adjustable Power Lens Rifle Optic Facts
Variable power rifle scopes have adjustable power. It will note the magnification level in a configuration like 2-10×32. These numbers imply the magnification of the scope can be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Glass
Here are some recommended scope power levels and the distances where they can be efficiently used. Remember that higher power glass will not be as practical as lower powered optics and scopes since increased zoom can be a bad thing. The exact same idea applies to extended distances where the shooter needs to have increased power to see exactly where to best aim the rifle.
About Lens Finish
All present day rifle optic and scope lenses are coated. Lens coating is an important aspect of a rifle’s setup when thinking about high end rifle optics and scope equipment.
ED Versus HD Optics
Some rifle glass producers will also use “HD” or high-definition glass coverings that make the most of various processes, polarizations, rare earth compounds, and components to extract numerous colors and viewable target visibility through the lens. This high-def covering is often used with more costly, high density lens glass which drops light’s opportunity to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around things with hard shapes as light hits the object from various angles.
Single Finish Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses typically have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker 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” covered. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can show that a producer is taking numerous steps to fight various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally does not necessarily suggest the multi-coated lens is better than a single coated lens. Being “much better” is dependent on the maker’s lens treatment technology and the quality of materials used in constructing the rifle optic.
Rifle Optic Lens Anti-water Covering
Water on an optic’s lens doesn’t help with preserving a clear sight picture through an optic at all. 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 type of treatment. It treats the surface area of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Rifle Glass Installation Alternatives
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use manual levers which enable rifle shooters to rapidly mount and remove the scope.
Hex Key Scope Ring Mounts
Basic, clamp-on style 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 two separate rings to support the optic, and are normally made from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This type of scope mount is excellent for rifle systems which need a durable, rock solid mount which will not shift despite just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a dedicated scope system on a long distance hunting or competition firearm which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to stop the hex screws from wiggling out after they are mounted tightly in position. An example of these rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Glass Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These types of mounts are useful and practical for shooting platforms which are hauled around a lot, to take off the scope from the rifle for protection, or for optics which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your highly-priced optic by resulting in fogging and producing residue within the scope’s tube. Most scopes protect against humidity from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these water-resistant 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 humidity prevention for standard use rifles, unless you intend on taking your rifle on boats and are concerned about the optic still working if it falls overboard and you can still retrieve the firearm.
Rifle Optic Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less altered by climate alterations and pressure variations from the external environment which could potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
