Information About Glass
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adapted to take into account various environmental things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have around eleven parts which are found internally and outside of the scope. These parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other parts. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Glass
First focal plane scopes (FFP) include the reticle before the magnification lens. This induces the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their aim point “hold over” and “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the exact same scale in relation to the volume of zoom being used. The end result is that the reticle measurements change based upon the magnification employed to shoot over longer ranges due to the fact that the reticle markings present different increments which can vary with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These kinds of optics work for:
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who prefer a clearer optic picture without room used up by the larger sized FFP reticle
Optic Magnification
The amount of scope magnification you require depends upon the type of shooting you want to do. Just about every style of rifle glass delivers some level of zoom. The volume of magnification a scope provides is determined by the dimension, density, and curvatures of the lens glass inside of the rifle optic. The magnification of the optic is the “power” of the opic. This implies what the shooter is checking out through the scope is magnified times the power factor of what can generally be seen by human eyes.
Single Power Lens Scopes
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a fixed power scope.
Variable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power modification is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the ranges where they may be effectively used. High power glass will not be as efficient as lower magnification glass considering too much magnification can be a bad thing. The exact same concept applies to extended ranges where the shooter needs to have enough power to see precisely where to properly aim the rifle at the target.
Rifle Optic Lens Coating
All contemporary rifle scope lenses are layered. There are different types and qualities of glass lens finishes. When thinking about high end rifle optical systems, Lens finishing can be an essential element of defining the capability of the rifle. The lenses are one of the most crucial pieces of the scope since they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses safeguards the lens exterior and helps with anti glare from refracted direct sunlight and color profiles.
About Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different processes, chemicals, elements, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can also have various finishings applied to them. All lenses normally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a finishing put on it so that it will be efficiently usable in lots of kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less beneficial 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 producers likewise make it a point to define if their optic lenses are covered or “multi” covered. This indicates the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a manufacturer is taking several steps to fight different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also does not necessarily suggest the multi-coated lens will perform much better than a single layered lens. Being “much better” depends on the maker’s lens treatment innovation and the quality of components used in building the rifle optic.
Anti-water Lens Coatings
Water on a lens does not help with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic finish which is water repellent.
Options for Installing Rifle Optics on Firearms
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use toss levers which enable rifle shooters to rapidly install and dismount the optics.
Hex Key Rifle Optic Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is great for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a similar style mount, multiple scopes can also be switched out on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These kinds of mounts are useful and convenient for rifles which are transferred a lot, to take off the glass from the rifle for protection, or for aiming systems which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Many scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
What to Know About Rifle Optic Tube Gas Purging
Another element of preventing the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less impacted by condition changes and pressure variations from the outdoor environment which could potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
