Rifle Glass Details
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adapted to take into account separate environmental things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes have around 11 parts which are arranged within and externally on the scope body. These parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the finest type of rifle glass is based around what type of shooting you plan on doing.
Info About First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are low
- Experienced shooters who know their target “hold over” plus “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the zoom lens. This causes the reticle to stay at the very same overall size relative to the volume of zoom being used. The outcome is that the reticle dimensions shift based upon the zoom chosen to shoot over lengthier ranges because the reticle measurements represent different increments which fluctuate with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These kinds of scopes are handy for:
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and spaces
- Shooters who choose a clearer optic picture with less space used up by the larger size FFP reticle
About Rifle Scope Magnification
The quantity of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info on Fixed Power Lens Rifle Scopes
A single power rifle scope or optic will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a fixed power scope.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes can be modified between magnified settings. The power adjustment is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope powers and the ranges where they could be effectively used. Always remember that higher magnification scopes and optics will not be as effective as lower magnification level glass due to the fact that too much magnification can be a detractor. The same concept relates to extended distances where the shooter needs to have increased power to see where to best aim the rifle at the target.
About Rifle Optic Lens Coating
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of coverings. When looking at high end rifle scope devices, Lens finishing can be a vital component of a rifle. The glass lenses are one of the most essential pieces of the scope given that they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens exterior as well as assists with anti glare from refracted sunrays and color recognition.
HD Versus ED Optic Lens Coatings
Some glass producers also use “HD” or high-definition lense finishings which apply different procedures, elements, polarizations, and chemical applications to enhance numerous colors and viewable target definition through the lens. This HD finish is often used with higher density glass which decreases light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often obvious over objects with defined shapes as light hits the item from various angles.
Single Finish Versus Multi-Coating
Different optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finish applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a covering put on it so that it will be optimally usable in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect 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 coated lens depends on the scope company and the amount you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has had several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can show that a producer is taking several actions to fight different natural elements like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also doesn’t always mean the multi-coated lens is much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of products used in building the rifle optic.
Hydrophobic Rifle Optic Lens Covering
Water on a lens does not help with retaining a clear sight picture through a scope at all. Many top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Scope Mounting Options
Mounting options for scopes come in a few choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the optics.
Hex Key Rifle Optic Rings
Standard, 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is fine for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can also be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and practical for shooting platforms which are hauled around a lot, to remove the glass from the rifle for protection, or for scopes which are chosen for use in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can ruin a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another component of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less altered by temp alterations and pressure variations from the external environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
